!!Warning!! UDMA and Fujitsu HD

Hi

I am having problems with a hard disk Fujitsu MPB3064AT UDMA and the
kernel 2.0.34 (Red Hat 5.1 and Slackwere 3.5).

Under this kernel, fdisk does not work correctly, if you have already
the partitions you can format it (mke2fs), but if you check it
afterwards
(e2fsck -f) it appears corrupted inmediately. If you try to copy
something
in there ... corrupted.

It seems that the new support included for UDMA in 2.0.34 is not
compatible with this Fujitsu. I installed this distributions using an
older
kernel (2.0.31) and they worked ok.

This happens also with hdparm, if you try to make it full UDMA, it
inmediately gets corrupted and you loose everything.

In the list of RedHat 5.1 I could find two more with exactly the same
problem, one with the same Hard Disk but the other with a different one.

I hope this helps

Cheers
