The Read Defect Data command on most SAS SSD is going to return CHECK CONDITION for request of LBA, CHS, BFI format. Usually for KCQ=01/1C/02 "defect list not found". This is because the retired NAND media does not fit any of those convictions. Most SAS SSD vendors will support and return a vendor unique format which depending on the vendor may not give you the format definition. Then this command becomes useful only to the vendor. Fortunately, most vendors provide other means to look at bad blocks. My issue is that I use smartctl a lot and every time I run it during a long test run, it generates a bunch of CHECK CONDITIONS in my outputs that I have to filter out. Could smartctl omit the Read Defect Data command if the device is an SSD? or provide a switch so that I can disable checking for defect through Read Defect Data? |

On Darwin (OSX) ATA_LOG_EXT command is not implemented, as well as on some other outdated ATA interfaces. However i found that device statistic is readable using smartlog 0x04 page. This is sample output with my dirty hack for darwin: Device Statistics (SMART Log 0x04) Page Offset Size Value Description 1 ===== = = == General Statistics (rev 2) == 1 0x008 4 544 Lifetime Power-On Resets 1 0x010 4 413 Power-on Hours 1 0x018 6 4466199876 Logical Sectors Written 1 0x020 6 23335260 Number of Write Commands 1 0x028 6 4027657571 Logical Sectors Read 1 0x030 6 16200567 Number of Read Commands 4 ===== = = == General Errors Statistics (rev 1) == 4 0x008 4 0 Number of Reported Uncorrectable Errors 4 0x010 4 0 Resets Between Cmd Acceptance and Completion 6 ===== = = == Transport Statistics (rev 1) == 6 0x008 4 0 Number of Hardware Resets 6 0x010 4 0 Number of ASR Events 6 0x018 4 0 Number of Interface CRC Errors 7 ===== = = == Solid State Device Statistics (rev 1) == 7 0x008 1 0~ Percentage Used Endurance Indicator |_ ~ normalized value Correct logic on -ldevstat should be:
Also os_darwin.cpp needs to be converted to the new interface (#103) to support multi-sector requests. |

I am getting an "invalid SMART checksum" error when I run smartctl and there is not documentation for it and I can't find anything on the web about it so I think it may be a bug. Please investigate. Thank you. |
