Re: USB disks

I have experienced the same issue using USB hard drives when using Fedora. It's strange you have to reboot the OS. Is there anyone who knows how to avoid a reboot in these situations?

Geofrey,

I found the problem.

RedHat has to be booted. The USB disk cannot have any electrical
current to the disk.
Then connect the USB to the RedHat system. Now plug the USB disk into
the electrical
current to turn it on.

You will see the disk listed using

lsusb

Reboot your system and the USB disk is recognized as the old /dev/sdb
again.

I don't know why this works, but I am glad I have it working again.

Thanks for all your help.

Try unplugging it, then type:

# tail -f /var/log/messages

Then plug it back in - you should see messages written to this file.

Nope. I just see the system disk.

Can you see the device with:

# fdisk -l

I have a laCie auxiliary disk which has been working on a 2.4.21-53
RedHat system. The disk was accidently turned off during the
afternoon. Now I cannot get the device recognized by the system
again. The system can't open /dev/sdb.

I was able to mount the disk on a newer RedHat system, but I need to
get it working on the previous system.

What should I do next?
