Same Problem here, the harddrive (2.5" Samsung HM121HC) running with Kernel 2.6.18-194.32.1.el5 (x86_64) produces errors on high load. With one step back kernel the errors are gone. Im already changed the harddrive with a new one, same errors on the newest kernel.
dmesg output:
hdc: status error: status=0x58 { DriveReady SeekComplete DataRequest } ide: failed opcode was: unknown hdc: drive not ready for command attempt to access beyond end of device hdc3: rw=0, want=25863980832, limit=225841770 attempt to access beyond end of device hdc3: rw=0, want=7830939224, limit=225841770 attempt to access beyond end of device hdc3: rw=0, want=31645262224, limit=225841770 attempt to access beyond end of device hdc3: rw=0, want=25863980832, limit=225841770 attempt to access beyond end of device hdc3: rw=0, want=25863980832, limit=225841770 hdc: status error: status=0x58 { DriveReady SeekComplete DataRequest } ide: failed opcode was: unknown hdc: drive not ready for command
There are no errors logged in smart, i already try'd with smartctl -t long .... no errors. I also did a blocktest on this drive. Next step is to change the cables, but i don't think this would be a solution, i think it's a kernel IDE / DMA problem.

I hope to be be getting some custom made 80 wire UDMA IDE cables sorted ASAP. That should squeeze extra speed from all the drives on the machine.
You shouldn't need custom cables. IDE 80 pin cables can be sourced all over the Internet for around $5 a cable. Prices have gone up since they are now not common. You might even post a wanted ad on craigslist and see if you can get a handful for a few bucks.
