Sorry, I don't know a solution for this.
I just want to say that I have the same problem with some machines. Apparently this is not a hardware problem (or not an obvious one...), since the HDDs are fine, no errors etc. Is that from time to time it produces this error. More frequently on a machine which has 8 HDDs on it, but the same thing happens on other machines with just one HDD on it (and different motherboards, CPU, etc.).

Hello
I've a server (standard intel pIV) with several 200GB disks (5 Western Digital) for the data and a 60 GB for the system. some disks are connected to the mobo ide (intel ICH4) and some to an additional ide card (Silicon Image PCI0680).
I've got the following errors on almost all 200 GB disks (but none on the system disk hda)
kernel: hde: dma_intr: status=0x51 { DriveReady SeekComplete Error } kernel: hde: dma_intr: error=0x40 { UncorrectableError }, LBAsect=4194146, high=0, low=4194146, sector=4194144 kernel: end_request: I/O error, dev 21:00 (hde), sector 4194146
very early. thought, it worked a while (maybe users didn't need the files with errors ?). the things were worse so I decided to check it all from the beginning.
I downloaded WD tools, checked all the disks (75 mn low level scan), and no disk gave any error. then I rebuilt the LVM (one VG, one LV) and the file system (920GB XFS). everything went fine for 2 days.
now I'm getting those errors again.
WD says it might be a software bug (linux drivers, kernel, bios...) causing those unreadable sector errors...
I'd really appreciate any clue...
PS I set the machine bios up-to-date during tests, no change. PS2 and actually I have 2 identical machines with the same problem (so obviously I can't think of an hardware problem !) PS3 both machines have high-grade UPS so neither is it an power supply problem !
TIA
