After this "crash" I have to power the drive off and back on to get it to work again. I have tried different cables and different ports on the USB2 card and this still happens, also if the drive is mounted and this happens then I can't unmount it so I end up with: /dev/sda1 on /media/disk type ext3 (rw,noatime) /dev/sdb1 on /media/disk type ext3 (rw,noatime) /dev/sdc1 on /media/disk type ext3 (rw,noatime) Current kernel is: Linux shredder 2.6.26-1-686 #1 SMP Mon Dec 15 18:15:07 UTC 2008 i686 GNU/Linux Upgraded from etch to lenny hoping the new kernel would help, which it hasn't. Anybody had and solved this issue? What else can I do to debug? -- Thank you, Clifford W. Hansen PHP Developer / Linux Administrator "We have seen strange things today!"
