A while ago, I saw a rash of errors on a hard drive at the same alleged sector:
Jul 26 06:30:12 ithaki kernel: hdb: drive_cmd: error=0x7f { DriveStatusError UncorrectableError SectorIdNotFound TrackZeroNotFound AddrMarkNotFound }, LBAsect=1647111536511, high=98175, low=8355711, sector=0 Jul 26 06:30:12 ithaki kernel: hdb: drive_cmd: status=0x7f { DriveReady DeviceFault SeekComplete DataRequest CorrectedError Index Error } Aug 6 06:30:18 ithaki kernel: hdb: drive_cmd: error=0x04 { DriveStatusError } Aug 6 06:30:18 ithaki kernel: hdb: drive_cmd: status=0x51 { DriveReady SeekComplete Error } Aug 12 01:10:17 ithaki kernel: hdb: drive_cmd: status=0x7f { DriveReady DeviceFault SeekComplete DataRequest CorrectedError Index Error } Aug 12 01:10:18 ithaki kernel: hdb: drive_cmd: error=0x7f { DriveStatusError UncorrectableError SectorIdNotFound TrackZeroNotFound AddrMarkNotFound }, LBAsect=1647111536511, high=98175, low=8355711, sector=0 Aug 14 01:10:33 ithaki kernel: hdb: drive_cmd: error=0x7f { DriveStatusError UncorrectableError SectorIdNotFound TrackZeroNotFound AddrMarkNotFound }, LBAsect=1647111536511, high=98175, low=8355711, sector=0 Aug 14 01:10:33 ithaki kernel: hdb: drive_cmd: status=0x7f { DriveReady DeviceFault SeekComplete DataRequest CorrectedError Index Error }
In hex, that LBAsect is 0x17f7f7f7f7f. The disk is:
Model Number: WDC WD3000JB-00KFA0 Serial Number: WD-WCAMR2255526 Firmware Revision: 08.05J08
Kernel is Linux ithaki 2.6.16.18d865-sata #1 SMP Wed May 31 17:10:12 PDT 2006 i686 GNU/Linux. IDE controller is:
0000:00:1f.1 IDE interface: Intel Corp. 82801EB/ER (ICH5/ICH5R) Ultra ATA 100 Storage Controller (rev 02)
FS is ext3. smartctl didn't report any errors but, then, it wouldn't necessarily if the problem was garbage fs metadata. I found a few other LKML postings with 0x7f patterns in part of the LBAsect. http://www.ussg.iu.edu/hypermail/linux/kernel/0605.3/1124.html http://www.ussg.iu.edu/hypermail/linux/kernel/0405.2/1227.html http://www.ussg.iu.edu/hypermail/linux/kernel/0307.2/1725.html
I haven't found any postings in which anyone points out the 0x7f pattern, which is why I thought I should post. I've failed to reproduce the problem since the above dates. I'm not subscribed to the list but would be interested to be cc()d on any replies. ------------------------------------- Martin's Outlook, BlueArc Engineering
