Bad s-ata driver or currupt hardware

Tue Apr 20 01:03:44 PDT 2004

I have a very strange problem. I can't copy large files
localy on the harddrive, the original and the new file is
not the same.
It does not occor all the time but frequently enought to
be very annoying.

The system is a brand new Amd Duron with Kingston memmory.

Example:
dd if=/dev/urandom of=~/test.fil bs=100000000 count=1;
time cp test.fil tmp/test.fil.copy;diff test.fil
tmp/test.fil.copy
1+0 records in
1+0 records out
100000000 bytes transferred in 7.351899 secs (13601928
bytes/sec)

real    0m3.438s
user    0m0.024s
sys     0m1.224s
Binary files test.fil and tmp/test.fil.copy differ
