I am having trouble using a Maxtor OneTouch external drive (an older

model 250GB drive) on a 4.1 Ipex Celeron box. I suspect that the drive

itself is the problem but I wanted to get some other opinion.
The most recent error resulted in the following output: The first part

is when I plugged the drive in, the second when the error occurred while

running an rdiff-backup process using the drive as the destination.

Any help is appreciated. Mostly when this happens the drive ends up

uncleanly mounted and fsck is needed to fix various disk errors.
The current USB controller is a VIA VT83C572 on a PCI card, but I also

had similar problems with an Intel 82801DB controller that is on the MB.
Cheers,
