when i run long tests in debian sid, they usually get interrupted: > SMART Self-test log structure revision number 1 > Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error > # 1 Extended offline Completed without error 00% 77 - > # 2 Short offline Completed without error 00% 74 - > # 3 Extended captive Interrupted (host reset) 90% 73 - > # 4 Extended captive Interrupted (host reset) 90% 3 - > # 5 Extended offline Interrupted (host reset) 40% 3 - > # 6 Conveyance offline Completed without error 00% 0 - > # 7 Short offline Completed without error 00% 0 - dmesg shows the following line near the interruption time for test #2: > [153384.901218] usb 1-1.1: reset high-speed USB device number 6 using ehci-pci in the one successful long test, i didn't use the "-C" option. in the prior test, which was interrupted, i did. for the other interrupted tests, i tested it with and without the "-C" option while using an older kernel. (perhaps i had "ejected" the disk through the gui before starting... i don't actually know, since it was a long time ago.) is the kernel doing this because the drive is not fully accessible during a test? my online search didn't reveal much, except for a forum post i found a while back. unfortunately, i didn't save the link. :-( if anyone knows why this is happening or how to best avoid this problem, i can add it to the faq for you. thanks! -andrew p.s. please CC me in replies. here is more of the dmesg log, for more context: > [153143.087642] usb 1-1.1: new high-speed USB device number 5 using ehci-pci > [153143.599687] usb 1-1.1: new high-speed USB device number 6 using ehci-pci > [153143.692937] usb 1-1.1: New USB device found, idVendor=1058, idProduct=10a8 > [153143.692943] usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 > [153143.692946] usb 1-1.1: Product: Elements 10A8 > [153143.692949] usb 1-1.1: Manufacturer: Western Digital > [153143.692951] usb 1-1.1: SerialNumber: <edited> > [153143.693345] usb-storage 1-1.1:1.0: USB Mass Storage device detected > [153143.693632] scsi7 : usb-storage 1-1.1:1.0 > [153144.692345] scsi 7:0:0:0: Direct-Access WD Elements 10A8 1042 PQ: 0 ANSI: 6 > [153144.696752] sd 7:0:0:0: [sdb] Spinning up disk... > [153145.699649] .....ready > [153149.962446] sd 7:0:0:0: [sdb] 1953458176 512-byte logical blocks: (1.00 TB/931 GiB) > [153149.963666] sd 7:0:0:0: [sdb] Write Protect is off > [153149.963674] sd 7:0:0:0: [sdb] Mode Sense: 53 00 10 08 > [153149.964829] sd 7:0:0:0: [sdb] No Caching mode page found > [153149.964837] sd 7:0:0:0: [sdb] Assuming drive cache: write through > [153149.967766] sd 7:0:0:0: [sdb] No Caching mode page found > [153149.967774] sd 7:0:0:0: [sdb] Assuming drive cache: write through > [153150.016976] sdb: sdb1 sdb2 > [153150.021154] sd 7:0:0:0: [sdb] No Caching mode page found > [153150.021162] sd 7:0:0:0: [sdb] Assuming drive cache: write through > [153150.021169] sd 7:0:0:0: [sdb] Attached SCSI disk > [153384.901218] usb 1-1.1: reset high-speed USB device number 6 using ehci-pci |
