Maxtor 300gb external USB drive hangs

[Lasse K. Christiansen]

Hi all,

I've been trying to work around problems with my Maxtor external USB drive 
(can also use firewire).

The problems is that it mounts just fine and works for a brief period of time 
(not sure that it uses USB2 driver on my machine though) and in the middle of 
copying files it stops working and tells me that it cannot copy files. 
Invalid Block device and i cannot unmount it.

Only solution that i've found is a reboot ! and then it works for a couple of 
minutes again.

When i look at /var/log/messages it tells me that:

last message repeated 15 times
Mar  7 23:50:37 localhost modprobe: modprobe: Can't locate module 
block-major-68
Mar  7 23:50:37 localhost last message repeated 15 times
Mar  7 23:50:37 localhost modprobe: modprobe: Can't locate module 
block-major-69
Mar  7 23:50:38 localhost last message repeated 15 times

Then it continues this error for about 10 more times.

lsusb -v tells me (amongst other things that)

Have anyone seen anything similar ?? I've encountered this issue with all 
kernel for Fedora core 1 that i've tried. When booting knoppix and trying to 
copy files it just works ??


Any help will be greatly appreciated,

Thanks in advance
