Attributes

I see some strange output from `smartctl`. What does it mean?

The raw SMART attributes (temperature, power-on lifetime, and so on) are stored in vendor-specific structures. Sometime these are strange. Hitachi disks (at least some of them) store power-on lifetime in minutes, rather than hours (see next question below). IBM disks (at least some of them) have three temperatures stored in the raw structure, not just one. And so on.

If you find strange output, or unknown attributes, have a look at our wiki pages, were we collect vendor specific info:

When you don't find an answer to your question there, please send an email to smartmontools-support and we'll help you try and figure it out.

How can I get the attribute information in human readable format?

smartctl provides human readable format as far as possible. If the exact meaning of the RAW value is not known, there is nothing we can do.

Why is the attributes number and meaning different on the disks?

Unlike other parts of SMART (logs, self-tests), the attributes are not (and never were) part of the ATA standards. Even the general attribute format (ID, VALUE, WORST, RAW) is removed from the standard since ATA-4 (1998).

Attribute assignment and interpretation are vendor/device specific and undocumented in many cases.

What details can be interpreted from `Raw read error rate`?

If no documentation is available, the RAW value of attribute 1 is typically useless. The 48-bit field might encode several values, try -v 1,hex48 to check.

Why is my disk temperature s reported by `smartd` as 150 Celsius?

It's not. Please read the end of the smartd man page (NOTES). For example, in the message:

 Device: /dev/hda, SMART Attribute: 194 
 Temperature_Celsius changed from 94 to 93

the value given is the Normalized not the Raw Attribute value (the disk temperature in this case is about 22 Celsius). The '-R' and '-r' Directives modify this behavior, so that the information is printed with the Raw values as well, for example:

 Device: /dev/hda, SMART Attribute: 194 
 Temperature_Celsius changed from 94 [Raw 22] to 93 [Raw 23]

Here the Raw values are the actual disk temperatures in Celsius. The way in which the Raw values are printed, and the names under which the Attributes are reported, is governed by the various '-v Num,Description' Directives described in the smartd man page. Please see the smartctl manual page for further explanation of the differences between Normalized and Raw Attribute values.

Attribute 194 (Temperature Celsius) behaves strangely on my Seagate disk

Some Seagate disks store the current temperature Celsius in both the RAW and NORMALIZED Attribute 194 values, and the maximum lifetime temperature in Celsius in the WORST value. Since cooler is better, this means that in this case, lower NORMALIZED Attribute values are farther from failure, and that over time the WORST Attribute values get larger, not smaller (as with other Attributes).

`smartctl` reports the age as thousands of hours for my Maxtor/Hitachi/Fujitsu disk , yet it is only a few days old

On recent disks, Maxtor has started to use Attribute 9 to store the power-on disk lifetime in minutes rather than hours. In this case, use the: '-v 9,minutes' option to correctly display hours and minutes.

Some models of Fujitsu disks use Attribute 9 to store the power-on disk lifetime in seconds. In that case, use the: '-v 9,seconds' option to correctly display hours, minutes and seconds.

The power-on timer (Attribute 9 raw value) on my Maxtor disk acts strange.

There are three related problems with Maxtor's SMART firmware:

On some Maxtor disks, the raw value of Attribute 9 (Power On Time) is supposed to be minutes. But it advances at an unpredictable rate, always more slowly than one count per minute. This is because when the disk is in idle mode, the counter stops advancing. This is only supposed to happen in standby mode. This will be corrected in Maxtor product lines released after October 2004.
In Maxtor disks that use the raw value of Attribute 9 as a minutes counter, only two bytes (of the six available) are used to store the raw value. So it resets to zero once every 65536=2¹⁶ minutes, or about once every 1092 hours. This is fixed in all Maxtor disks manufactured after July 2003, where the raw value was extended to four bytes.
In Maxtor disks that use the raw value of Attribute 9 as a minutes counter, the hour time-stamps in the self-test and ATA error logs are calculated by right shifting 6 bits. This is equivalent to dividing by 64 rather than by 60. As a result, the hour time stamps in these logs advance 7% more slowly than they should. Thus, if you do self-tests once per week at the same time, instead of the time-stamps being 168 hours apart, they are 157 hours apart. This is also fixed in all Maxtor disks manufactured after July 2003.

The time stamps in the self-test log don't correspond to the power-on time, when test was run on my Western Digital (WD) disk

The self-test log timestamps in many WD disks roll back to zero every 1092 hours (65536 minutes). This problem is due to a WD firmware bug. The power-on lifetime in hours is correctly stored in Attribute

However when the power-on lifetime is calculated for self-test log

entries, the lifetime in minutes is put into a 16-bit register then divided by 60. The 16-bit register overflows and wraps around every 1092 hours.

For WD drives that exhibit this firmware bug, the relationship between Attribute 9's raw value (H) and the time-stamps in the self-test log (h) are given by:

 Let H = power on hours as shown by Attribute 9 (correct)
 Let M = 60*H (power on minutes, correct)
 Let m = M mod 65536 (incorrect value of power on minutes)
 Let h = m/60 (incorrect value of power on hours, shown in self-test log)

The (normalized) WORST Attribute values of my Western Digital (WD) disk are larger than the (normalized) CURRENT Attribute values

Western Digital firmware initializes SMART Attributes 10, 11, and 199 after either 120 spin-ups or 8 power-on hours. Until that time, they have the uninitialized value 253.

The SSD_Life_Left Attribute of my new SandForce based SSD reports zero

It doesn't. The RAW value of this attribute is always 0 and has no meaning. Check the normalized VALUE instead. It starts at 100 and indicates the approximate percentage of SDD life left. It typically decreases when Flash blocks are marked as bad, see the RAW value of Retired_Block_Count:

ID# ATTRIBUTE_NAME          FLAGS    VALUE WORST THRESH FAIL RAW_VALUE
...
  5 Retired_Block_Count     PO--CK   098   098   003    -    416
...
231 SSD_Life_Left           PO--C-   097   097   010    -    0

The Power_On_Hours Attribute of my new Intel SSD reports ~890000 hours

This is a bug in Intel 330 Firmware 300i and Intel 520 Firmware 400i. The offset is 894794 hours. See also ticket #289 and Intel SSD Toolbox SMART Attributes FAQ. The hours counter from Device Statistics is not affected:

Protocols, Devices and Controllers

Can I monitor disks behind RAID controllers?

Support for disks behind RAID controllers is highly dependent on both platform and controller type. See our page about smartmontools RAID controller support for the details.

What is error recovery control (ERC) and why it is important to enable it for the (S)ATA disks in RAID?

In computing, error recovery control (ERC) is a feature of hard disks which allow a system administrator to configure the amount of time a drive's firmware is allowed to spend recovering from a read or write error. Limiting the recovery time allows for improved error handling in hardware or software RAID environments. In some cases, there is a conflict as to whether error handling should be undertaken by the hard drive or by the RAID implementation, which leads to drives being marked as unusable and significant performance degradation, when this could otherwise have been avoided.

It is best for ERC to be "enabled" when in a RAID array to prevent the recovery time from a disk read or write error from exceeding the RAID implementation's timeout threshold. If a drive times out, the hard disk will need to be manually re-added to the array, requiring a re-build and re-synchronization of the hard disk. Limiting the drives recovery timeout helps for improved error handling in the hardware or software RAID environments.

On disks that fully implement the ATA-8 standard, the smartctl utility can be used to control the ERC behavior of many drives by setting the SCT Error Recovery Control (scterc) parameter:

Reading current settings:

     
smartctl -l scterc /dev/sda
     SCT Error Recovery Control:
           Read: Disabled
          Write: Disabled

Changing the setting:

smartctl -l scterc,150,150 /dev/sda
    SCT Error Recovery Control:
               Read:    150 (15.0 seconds)
              Write:    150 (15.0 seconds)

ERC control needs to be set on the boot time and if hot-replacement been made. You may find sample Linux scripts and related discussion in the ticket #658.

Smartmontools for FireWire, USB, and SATA disks/systems

As for USB and FireWire (IEEE 1394) disks and tape drives, the news is not good. They appear to the operating system as SCSI devices but their implementations do not usually support those SCSI commands needed by smartmontools. A consortium associated with IEEE 1394 certified some external enclosures (containing a ATA disk and a protocol bridge) as being compliant to the relevant standards. Even still, that compliance means that they tend to only support the bare minimum of commands needed for device operation (i.e. SMART support is an unsupported extra). Hopefully external USB and Firewire devices will support SAT in the future, see below. Some USB device based on cypress chips support a proprietary protocol (ATACB) that allow to send raw ATA commands (i.e. SMART support).

Smartmontools should work correctly with SATA drives under both Linux 2.4 and 2.6 kernels. Depending on which subsystem the SATA controller is in (i.e. drivers/ide, drivers/ata or libata (under drivers/scsi) a SATA drive will appear as /dev/hd* or /dev/sd*. Either way, smartmontools should be able to figure out what is going on and act accordingly. In some cases smartmontools may need a hint in the form of a '-d sat' or '-d ata' option on the smartctl command line or in the /etc/smartd.conf file. There may be a hint to add one of those options in the log file when smartd is run as a daemon or on the command line with smartctl. The '-d ata' option means that even though the drive has a SCSI device name, treat it as an ATA disk. Unfortunately such an approach doesn't often work. The next paragraph has more information about '-d sat'.

The SCSI to ATA Translation (SAT) standard (ANSI INCITS 431-2007) may solve many problems in this area. It defines how SCSI commands will be translated to the corresponding ATA commands and defines a pass-through mechanism. ATA commands are conveyed natively by two transports: parallel and serial ATA. SCSI commands can be conveyed by many transports: the veteran SCSI Parallel Interface (SPI), Fibre Channel (FC), Infiniband (SRP), Serial Attached SCSI (SAS), IP (iSCSI and iSER), USB (mass storage), and IEEE 1394 (SBP) to name some. Due to their cost and storage capacity, more and more ATA disks (especially SATA disks) are appearing "behind" a SCSI transport. This is especially true of the SAS transport which can painlessly accomodate both SAS and SATA disks. Enter another acronym: SATL which stands for SCSI to ATA Translation Layer. In Linux libata has a SATL in it. Some SAS host bus adapters have a SATL in their firmware. FC might have a SATL in a switch. Perhaps in the future USB and IEEE 1394 enclosures will have a SATL in them. Starting from smartmontools versions 5.36 and 5.37, no matter where a SATL is, irrespective of the operating system in use, the user should have less problems with ATA disks, no matter which transport is involved. As always, it helps to know a little of what is happening under the covers. The '-d sat' option instructs smartctl and smartd to assume a SATL is in place and act accordingly. The smartctl command can often detect a SATL and autoconfigure while in smartmontools version 5.37 smartd often needs a hint.

The current USB mass storage specification is based on a version of SCSI (SPC-2) that can't support SAT. But some chips manufacturers implement proprietary SCSI commands that allow ATA pass through (similiar like for SAT). Well known is the cypress chipset, that contains an ATACB proprietary pass through (for ATA commands passed through SCSI commands) for which some information is publicly available. Smartmontools 5.39 supports these cypress chips via the '-d usbcypress' option on the smartctl command line. A lot of devices can be autodetected already. Have a look on the wiki page about supported USB-Devices, wether your device is on the list. Check your device usb id (most cypress usb ata bridge got vid=0x04b4, pid=0x6830) or to try to call smartctl with option '-d usbcypress'. If the usb device doesn't support ATACB, smartmontools will abort.

Smartmontools for SCSI disks and tapes (TapeAlert)

Smartmontools for SCSI disks and tapes (including medium changers) is discussed on a separate page.----

Smartmontools for the NVMe devices

Smartmontools supports NVMe interface starting from version 6.5. NVMe related functionality and supported configurations are discussed on the NVMe wiki page.

Smartmontools Database

My ATA/SATA drive is not in the `smartctl`/`smartd` database

Does this break anything? How do I get it added?

If your drive is not in the database, then the names of the Attributes (displayed in the ATTRIBUTE_NAME column of smartctl -A /dev/sdX) and the format of the the raw Attribute values shown in the RAW_VALUE column may be incorrect. This is mostly cosmetic: the essential drive health monitoring/testing functionality of smartmontools does not depend upon the database.

If your drive is not in the database, please make sure to update the drive database first. Please do not submit a new drive for the database without checking to see if it is already in the current drive database (drivedb.h ) file.

If your drive is not in the current database, to have it added to the database, first use the command:

smartctl -t short /dev/sdX

to run a short self-test on the drive, and wait a few minutes for the test to complete. Then create a full smartmontools report and redirect it to a text file:

smartctl -x /dev/sdX > smartctl-VENDOR-MODEL.txt

The timestamp in the self-test log will help us to determine whether Attribute 9 is being used to store the lifetime in hours, minutes, or seconds.

Alternatively you could use:

smartctl -q noserial -x /dev/sdX > smartctl-VENDOR-MODEL.txt

This report does not contain the "Serial Number" and "LU WWN Device Id" output lines.

Then either email the file to smartmontools-database mailing list or create a ticket here in trac. Add the file as a plain-text ASCII attachment to avoid reformatting. In tickets, wiki markup for preformatted text could be used alternatively.

Place the drive model name in the email subject or ticket summary. To submit info about different drive models, please use separate emails or tickets.

Further information about the drive is welcome (link to device specification, output from a vendor specific SMART tool, name of the SSD controller, an already tested drivedb.h entry, ...).

Please note that there usually will be no feedback on the smartmontools-database mailing list after a drive has been added to the database. If such feedback is desired, please create a ticket instead.

Selftests

ATA drive is failing self-tests, but SMART health status is 'PASSED'. What's going on?

If your ATA drive supports self-tests, you should run them on a regular basis, for example one per week:

 smartctl -t long /dev/hd?

After the test has completed, you should examine the results with:

 smartctl -l selftest /dev/hd?

If the drive fails a self-test, but still has 'PASSED' SMART health status, this usually means that there is a corrupted (uncorrectable=UNC) sector on the disk. This means that the ECC data stored at that sector is not consistent with the user data stored at that sector, and an attempt to read the sector fails with a UNC error. This can be a one-time transient effect: a sudden power failure while the disk was writing to the sector corrupted the ECC code or data, but the sector <em>could</em> correctly store new data. Or it can be a permanent effect: the magnetic media has been damaged by a bit of dust, and the sector could not correctly store new data.

If the disk can read the sector of data a single time, and the damage is permanent, not transient, then the disk firmware will mark the sector as 'bad' and allocate a spare sector to replace it. But if the disk can't read the sector even once, then it won't reallocate the sector, in hopes of being able, at some time in the future, to read the data from it. A write to an unreadable (corrupted) sector will fix the problem. If the damage is transient, then new consistent data will be written to the sector. If the damange is permanent, then the write will force sector reallocation. Please see Bad block HOWTO for instructions about how to force this sector to reallocate (Linux only).

The disk still has passing health status because the firmware has not found other signs of trouble, such as a failing servo.

Such disks can often be repaired by using the disk manufaturer's 'disk evaluation and repair' utility. Beware: this may force reallocation of the lost sector and thus corrupt or destroy any file system on the disk. See Bad block HOWTO for generic Linux instructions.

`Unreadable, uncorrectable, pending` sectors or `Medium error` on disk. What's going on?

SCSI and ATA disk drives store data in blocks (sectors) of 512⁽¹⁾ bytes. Each 512 bytes of user data is stored on the media plus 40 or more bytes of ECC data included in it. These - so called ECC Bytes - are used internally by the disk firmware for error checking/detection and correction.

Sometimes the data in a sector gets corrupted. This can happen because a speck of dust scratched the disk, or because the disk was powered down while writing data to that sector, or for other reasons. Usually the ECC bytes can be used to correct the corrupted data. However if the ECC bytes are inconsistent or can't be used to correct the bad data, then the 512 bytes of data are lost. Such a sector is called unreadable or uncorrectable.

If your disk has an unreadable sector, this means that some of your data can't be retrieved. You can force the disk to replace the unreadable sector with a spare good sector, but only at the price of losing the 512 bytes of data forever.

Disks with uncorrectable sectors can often be repaired by using the disk manufaturer's 'disk evaluation and repair' utility (see previous FAQ entry). Beware: this may force reallocation of the lost sector and thus corrupt or destroy any file system on the disk. See Bad block HOWTO for generic Linux instructions.

Normally when an uncorrectable sector is found, the disk puts this onto a 'pending sector list' to indicate that it should be replaced with a spare good sector. However this replacement won't take place until either the disk can read the data on the bad sector, or is instructed to write new data to that bad sector.

(1) In the future the block size for disks (especially in the terabyte range) will increase from 512 bytes to 4096 bytes.

Why are long self-tests keep getting interrupted?

The host may send a standby command to the drive after some time of I/O inactivity. This also aborts any running self-test. The self-test log then reports Aborted by host or Interrupted (host reset) as status. This is typical for drives behind USB bridges.

As a workaround, run some tool or script which perform periodic low volume read accesses. See this thread on smartmontools-support mailing list for an example.

Where can I find manufacturer-specific disk-testing utilities?

A good listing of such utilities can be found here. Unfortunately most of these are for MS operating systems, but most can be run from a MS-DOS boot disk.

The UBCD (Ultimate Boot CD) includes most of these disk-testing utilities and many other useful diagnostic tools ready to boot from CD or USB memory stick. Recent UBCD releases contain Parted Magic which contains smartctl and GSmartControl, see the List of Live CDs/DVDs for further info.

Note: if you do run one of these utilities, and it identifies the meanings of any SMART Attributes that are not known to smartmontools, please report them to the smartmontools-support mailing list or add the info to our info pages on vendor specific SMART Attributes.

These utilities have an important role to fill. If your disk has bad sectors (for example, as revealed by running self-tests with smartmontools) and the disk is not able to recover the data from those sectors, then the disk will not automatically reallocate those damaged sectors from its set of spare sectors, because forcing the reallocation to take place may entail some loss of data. Because the commands that force such reallocation are Vendor Specific, most manufacturers provide a utility for this purpose. It may cause data loss but can repair damaged sectors (at least, until it runs out of replacement sectors).

Operating System

What are the operating system requirements?

Please see the first section of the INSTALL file.

BIOS has a SMART enable/disable setting. What does it do, and how should I set it?

Some type of BIOS can check the SMART health status of a disk at bootup: the equivalent of 'smartctl [-s on] -H /dev/sd?'. This one-time check on bootup is done if the BIOS SMART setting is set to ENABLE, and is not done if the setting is set to DISABLE.

If this one-time check is done, and the disk's health status is found to be FAILED, then typically the BIOS will display an error message and refuse to boot the machine.

For the proper functioning of smartmontools, either BIOS setting may be used.

A BIOS may perform the SMART health check even if it does not provide a corresponding setting. The check cannot be disabled in this case.

Do smartctl and smartd run on a virtual machine guest OS?

Yes and no. Smartctl and smartd run on a virtual machine guest OS without problems. But this isn't very useful because the virtual disks do not support SMART. If a guest OS disk is configured as a raw disk, this only means that its sectors are mapped transparently to the underlying physical disk. This does not imply the ATA or SCSI pass-through access required to access the SMART info of the physical disk. Even the disk's identity is typically not exposed to the guest OS.

What is the purpose of the command `smartctl-nc` on Windows?

The file smartctl-nc.exe (no console) from the smartmontools Windows package is a copy of smartctl.exe with the SUBSYSTEM type in the EXE header changed from CONSOLE to GUI. This prevents that an empty console window is opened when the command is run in background with output redirected. GSmartControl uses this command for this purpose. When smartctl-nc is run without redirection from a console window, its output is not visible because Windows detaches the program from the console.

`smartctl` aborts with the message "...SMART_GET_VERSION failed" on Windows. What is going wrong?

A failing SMART_GET_VERSION call means that the device driver does not implement the I/O controls (see below) to access ATA SMART functionality.

Some Windows drivers for (S)ATA controllers are implemented as SCSI class drivers. This is usually the case for drivers which support RAID. Unfortunately, such drivers do not support the ATA specific SMART I/O controls.

On Windows `smartctl` prints the message: "...Log Read failed: Function not implemented"

What is going wrong?

This means that the device driver does not support the command SMART READ LOG. The message does not indicate a hard disk problem'' It does also not mean that the disk itself does not support SMART logs. It may still be possible to read the logs with a Linux version of smartmontools run from some Live CD/DVD.

To access ATA SMART functionality on Windows, smartmontools uses the I/O control calls SMART_RCV_DRIVE_DATA and SMART_SEND_DRIVE_CMD. These calls were available since Win95 OSR2. An example program from Microsoft can be found here (the related KB article 208048 is no longer available).

Starting with NT4, these calls do more restrictive parameter checks. In particular, the command codes for SMART READ LOG and ABORT SELF-TEST are not accepted. To perform these functions, smartmontools uses the undocumented functions SCSIOP_ATA_PASSTHROUGH (NT4) or IOCTL_IDE_PASS_THROUGH (2000/XP) instead. An example program using these calls can be found here, a related newsgroup thread is here.

Unfortunately, these undocumented functions are not implemented in most vendor specific ATA device drivers. smartctl prints a "Function not implemented" message in this case.

A new I/O control call IOCTL_ATA_PASS_THROUGH is available since Win2003 and XP SP2. It should be supported by most new drivers. Experimental code using this call was added 2006-04-27 and is included in smartmontools release 5.37.

I found in syslog: 'Can't locate module block-major-65'

When I run smartd, the SYSLOG /var/log/messages contains messages like this:

smartd: Reading Device /dev/sdv 
modprobe: modprobe: Can't locate module block-major-65

This is because when smartd starts, if there is no configuration file, it looks for all ATA and SCSI devices to monitor (matching the pattern /dev/hd[a-t] or /dev/sd[a-z]). The log messages appear because your system doesn't have most of these devices.

The solution is simple: use the smartd configuration file /etc/smartd.conf to specify which devices to monitor.

Firmware Issues

'Error SMART Status command failed' What's the meaning of this `smartctl` message?

The SMART status command (health monitoring) is not working properly. This is found on USB 3.0 enclosures based on LucidPORT USB300 bridge with firmware 2447 or earlier. Firmware 2580 may fix this error. Contact both your enclosure manufacturer and LucidPORT to obtain a working firmware.

'Warning: ATA error count 9 inconsistent with error log pointer 5' What's the meaning of this `smartctl` message?

The ATA error log is stored in a circular buffer, and the ATA specifications are unambiguous about how the entries should be ordered. This warning message means that the disk's firmware does not strictly obey the ATA specification regarding the ordering of the error log entries in the circular buffer. Smartmontools will correct for this oversight, so this warning message can be safely ignored by users. (On the other hand, firmware engineers: please read the ATA specs more closely then fix your code!).

Distribution

Is there a bootable standalone CD/DVD that contains smartmontools?

Yes there are. See the list of Live CDs/DVDs containing smartmontools.

How can I check that the package hasn't been tampered with?

Since the smartmontools utilities run as root, you might be concerned about something harmful being embedded within them. Starting with release 5.19 of smartmontools, the released files have been GPG signed (except releases 5.37 to 5.39.1). The fingerprint are given in a file on the release page with a name like smartmontools-6.4.tar.gz.asc.

Please verify these using the

Historic

The FAQ entries below are probably outdated.

What Attributes does smartmontools not yet recognize?

From Maxtor disks (99), (100), and (101). These are not used by Maxtor in SMART revision 5. They will be used in SMART revision 6, but the engineering group has not yet decided what to monitor with these Attributes.

Startup message: `smartd [FAILED]` on Fedora Core Linux system

Fedora Core is distributed with a smartd configuration file /etc/smartd.conf that monitors the first IDE disk /dev/hda. If this device does not exist (or lacks SMART capability) you will get the error message above. Look in SYSLOG (/var/log/messages) for additional details about what is going wrong.

The solution: If your system has only SCSI disks, or has IDE disk(s) on a non-primary controller, just edit /etc/smartd.conf to reflect the correct location of the drive(s). Please also read the smartd.conf man page for additional information.

What's the story on IBM SMART disks?

Apparently some of the older SMART firmware on IBM disks can interfere with the regular operation of the disk. If you have this problem, here is a link to an IBM DeskStar hard disk drive firmware update.

Does it work on Windows?

Yes, finally it does. A windows port of smartctl 5.26 by Christian Franke was first checked in 2004/02/23 on CVS branch RELEASE_5_26_WIN32_BRANCH and has been merged to the CVS trunk later.

The Cygwin environment can be used to built both Cygwin and Windows (using MinGW) versions of smartctl and smartd. Installation instructions for binary distributions can be found here for Cygwin and here for Windows.

Why did the release version scheme change?

It was non-standard. So with the move to GNU Autoconf and GNU Automake it changed from 5.X-Y (where X and Y are one or more digits) to 5.Y. Starting with the first release, and moving forward in time, the releases are numbered as follows:

 5.0-1,
 5.0-2,
 ...,
 5.0-45,
 5.1-1,
 ...,
 5.1-18,
 5.19,
 5.20,
