=== Interpretation of S.M.A.R.T. Attributes ===
|| '''Device Model''' || '''Attributes ID#''' || '''Attributes Name''' || '''Special''' || '''Description''' ||
||   || 1 || Raw Read Error Rate || || Frequency of errors while reading raw data from a disk. ||
||   || 2 || Throughput Performance ||   || Average efficiency of a hard disk. ||
||   || 3 || Spin Up Time ||   || Time needed by spindle to spin-up. ||
||   || 4 || Start/Stop Count ||   || Number of start/stop cycles of spindle. ||
||   || 5 || Reallocated Sector Count ||   || Quantity of remapped sectors. ||
||   || 6 || Start/Stop Count ||   || Number of start/stop cycles of spindle. ||
||   ||   ||   ||   ||   ||
||   || '''7''' || '''Seek Error Rate''' ||  || Frequency of errors appearance while positioning. ||
||   ||   |||| [[Image(wiki:images:question.png)]] || ''I believe that the raw 48-bit Seek Error Rate attribute is encoded as follows:'' '''{{{topmost 16 bits=total number of seek errors, bottom 32 bits=total number of seeks}}}'''. ''Therefore the Seek Error Rate is equal to ...'' '''{{{(total number of seek errors) / (total number of seeks)}}}''' [http://forums.seagate.com/stx/board/message?board.id=ata_drives&message.id=8732#M8732 Reference]||
||   ||   ||   ||   ||   ||
||   || 8 || Seek Time Performance ||   || The average efficiency of operations while positioning. ||
||   ||   ||   ||   ||   ||
||   || '''9''' || '''Power-On Hours Count''' ||  || Quantity of elapsed hours in the switched-on state. ||
||   ||   |||| [[Image(wiki:images:exclamation.png)]] || ''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.'' ||
||   ||   ||   ||   ||   ||
||   || 10 || Spin-up Retry Count ||   || Number of retry attempts, that were needed to reach the operational speed of the spindle. ||
||   || 11 || Calibration Retry Count ||   || Number of attempts to calibrate a drive. ||
||   || 12 || Power Cycle Count ||   || Number of complete power on/off cycles of hard disk. ||
||   || 13 || Soft Read Error Rate ||   || Frequency of program errors appearance while reading data from a disk. ||
|| ''<unknown>'' || 192 || Power-Off Retract Cycle ||   || Number of power-off cycles. ||
||   || 193 || Load/Unload Cycle Count ||   || Number of cycles into Landing Zone position. ||
||   || 194 || HDA Temperature ||   || Temperature of a Hard Disk Assembly. ||
|| ''<unknown>'' || 195 || Hardware ECC Recovered ||   || Frequency of the on the fly errors. ||
||   || 196 || Reallocated Event Count ||   || Number of remap operations. That means replacing a bad sector by one from the spare area. ||
||   || 197 || Current Pending Sector Count ||   || Current number of unstable sectors (waiting for remapping). ||
|| ''<unknown>'' || 198 || Offline Scan Uncorrectable Count ||   || Number of uncorrected errors. ||
||   || 199 || UltraDMA CRC Error Rate ||   || Total number of errors CRC during UltraDMA mode. ||
||   || 200 || Write Error Rate ||   || Number of errors while writing to disk (or) flying height (?) ||
||   || 201 || Soft Read Error Rate ||   || Frequency of program errors appearance while reading data from a disk. ||
|| ''<unknown>'' || 202 || Data Address Mark Errors ||   || Number of Data Address Mark (DAM) errors (or) vendor-specific. ||
|| ''<unknown>'' || 203 || Run Out Cancel ||   || ECC Errors. ||
|| ''<unknown>'' || 204 || Soft ECC Correction ||   || Quantity of errors corrected by software ECC. ||
|| ''<unknown>'' || 205 || Thermal Asperity Rate (TAR) ||   || Frequency of the thermal asperity errors. ||
|| ''<unknown>'' || 206 || Flying Height ||   || The height of the disk heads above the disk surface. ||
|| ''<unknown>'' || 207 || Spin High Current ||   || Amount of high current used to spin up the drive. ||
|| ''<unknown>'' || 208 || Spin Buzz ||   || Number of buzz routines to spin up the drive. ||
|| ''<unknown>'' || 209 || Offline Seek Performance ||   || Drive's seek performance during offline operations. (Relation to Seek Time Performance - #8?) ||
|| ''<unknown>'' || 220 || Disk Shift ||   || Shift of disk is possible as a result of strong shock loading in the store, as a result of it's falling or for other reasons (sometimes: Temperature) ||
|| ''<unknown>'' || 221 || G-Sense Error Rate ||   || Frequency of mistakes as a result of impact loads as detected by a shock sensor(?). ||
|| ''<unknown>'' || 222 || Loaded Hours ||   || Number of hours in general operational state. ||
|| ''<unknown>'' || 223 || Load/Unload Retry Count ||   || Loading on drive caused by numerous recurrences of operations, like reading, recording, positioning of heads, etc. ||
|| ''<unknown>'' || 224 || Load Friction ||   || Load on drive caused by friction in mechanical parts of the store. ||
|| ''<unknown>'' || 225 || Load/Unload Cycle Count ||   || Number of cycles into Landing Zone position. ||
|| ''<unknown>'' || 226 || Load-in Time ||   || General time of loading for drive. ||
|| ''<unknown>'' || 227 || Torque Amplification Count ||   || Quantity efforts of the rotating moment of a drive. ||
