next in thread | raw e-mail | index | archive | help
If I copy large (500 meg) files between directories with DMA on, the
copy becomes corrupt. If I turn DMA off and use PIO mode, the copy is
fine. Smaller files do not seem to trigger this problem. I am using
STABLE from a couple of days ago, although I think I may have been
having this problem for a longer time. I have a Soyo KT333 Platinum
Dragon motherboard with a built in Highpoint IDE raid controller. The
corruption happens on my ar0 array, which is RAID 1 and consists of two
Western Digital 40g drives. fsck has never found any problems with
these drives. I'm using 80-pin cables, and the array used to run clean
(around 4.6 and before).
Any suggestions would be welcome. My dmesg follows:
