What does 'hdparm -d -u /dev/hdc' return?
What does 'dmesg | grep -C2 ide[0-4]' return?
Particularly, make sure DMA is on. If it isn't, check that your kernel
supports (and is setting up) your IDE controller(s) correctly. You can
also force DMA on by running 'hdparm -d1 /dev/hdc', but I don't
recommend doing that. If the kernel isn't setting DMA up automatically,
it's usually not a good idea to force the issue.
You can also enable the 'unmask IRQ' feature by running 'hdparm -u1
/dev/hdc', this will usually improve the responsiveness of the system
during heavy I/O, but read the hdparm(8) manpage and make sure the dire
warnings of FS corruption don't apply to your system
