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? ----- Original Message ----- From: "Margaret Doll" <Margaret_Doll@xxxxxxxxx> To: "General Red Hat Linux discussion list" <redhat-list@xxxxxxxxxx> Sent: Wednesday, January 23, 2008 11:35:53 PM (GMT+0100) Europe/Berlin Subject: Re: USB disks 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.
