I have a disk array on a machine: ... atapci3: <HighPoint HPT374 (channel 0+1) UDMA133 controller> port 0xc000-0xc0ff,0xbc00-0xbc03,0xb800-0xb807,0xb400-0xb403,0xb000-0xb007 irq 10 at device 15.0 on pci0 ata6: channel #0 on atapci3 ata7: channel #1 on atapci3 atapci4: <HighPoint HPT374 (channel 2+3) UDMA133 controller> port 0xd400-0xd4ff,0xd000-0xd003,0xcc00-0xcc07,0xc800-0xc803,0xc400-0xc407 irq 10 at device 15.1 on pci0 ata8: channel #0 on atapci4 ata9: channel #1 on atapci4 atapci5: <SiI 0680 UDMA133 controller> port 0xe800-0xe80f,0xe400-0xe403,0xe000-0xe007,0xdc00-0xdc03,0xd800-0xd807 mem 0xdf001000-0xdf0010ff irq 11 at device 17.0 on pci0 ata10: channel #0 on atapci5 ata11: channel #1 on atapci5 ... ad4: 78167MB <Maxtor 6Y080P0/YAR41BW0> [158816/16/63] at ata2-master UDMA133 ad6: 76319MB <MAXTOR 4K080H4/A08.1500> [155061/16/63] at ata3-master UDMA100 ad8: 76319MB <MAXTOR 4K080H4/A08.1500> [155061/16/63] at ata4-master UDMA100 ad10: 76319MB <MAXTOR 4K080H4/A08.1500> [155061/16/63] at ata5-master UDMA100 ad12: 76319MB <MAXTOR 4K080H4/A08.1500> [155061/16/63] at ata6-master UDMA100 ad14: 76319MB <MAXTOR 4K080H4/A08.1500> [155061/16/63] at ata7-master UDMA100 ad16: 76319MB <MAXTOR 4K080H4/A08.1500> [155061/16/63] at ata8-master UDMA100 ad18: 76319MB <MAXTOR 4K080H4/A08.1500> [155061/16/63] at ata9-master UDMA100 ad20: 76319MB <MAXTOR 4K080H4/A08.1500> [155061/16/63] at ata10-master UDMA100 ad22: 76319MB <ST380013A/8.01> [155061/16/63] at ata11-master UDMA100 And I'm having some odd behavior with Smartmontools. Most of the drives work fine, however ad20 returns what looks like corrupted data: smartctl version 5.32 Copyright (C) 2002-4 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION ==Device Model: 00MAXTOR 4K080H4 Serial Number: QT674131022929 Firmware Version: [No Information Found] Device is: Not in smartctl database [for details use: -P showall] ATA Version is: 1 ATA Standard is: Not recognized. Minor revision code: 0x3e Local Time is: Fri Feb 25 10:44:26 2005 EST SMART is only available in ATA Version 3 Revision 3 or greater. We will try to proceed in spite of this. SMART support is: Ambiguous - ATA IDENTIFY DEVICE words 82-83 don't show if SMART supported. A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options. Of course smartctl refuses to work with this drive (it works with all of the other ones). My first thought was that the firmware on the drive was somehow corrupt, but the drive otherwise appears to work fine. It even works pefectly if I use the DOS based disk manager that came with the drives (MaxBlast I think it was called). For comparision, a normal drive returns something like: smartctl version 5.32 Copyright (C) 2002-4 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION ==Device Model: MAXTOR 4K080H4 Serial Number: 674131125634 Firmware Version: A08.1500 Device is: In smartctl database [for details use: -P show] ATA Version is: 5 ATA Standard is: ATA/ATAPI-5 T13 1321D revision 1 Local Time is: Fri Feb 25 10:46:14 2005 EST SMART support is: Available - device has SMART capability. SMART support is: Enabled Is there something I can do to make that drive happier?
