Hello,

I have a question wrt. wd device writes. Writing a drive that does 
~4MBPS, UDMA-2 is only 320KBPS. It is a regular Seagate HDD connected to 
an Intel motherboard (P2/500MHz cpu). The low speed appears when copying 
a lot of data from a 52x cdrom. The speed should be at least 1MBPS. As 
is, the cd light flashes on once in a while and the hdd light is solidly 
on. Copying a reasonable amount of data takes 3-4 times as long as 
usual. No decompression is involved. Speed testing on read using dd 
yields much better speed (both cdrom and cd).

I also saw data corruption a few times on this disk. The disk itself is 
not faulty but fsck was unable to recover the problem.

This is on 1.6.1

thanks for any comments,
Peter
