Fedora 15 XFCE (the file manager is Thunar). I use an external USB

(formatted Ext4, same as my system) to backup my system. The drive
auto-mounts when I turn the notebook on.
I violently pulled the USB cable by accident. Both the drive and the
external HD were transferring data when it happened.
I turned off both devices, I checked the USB cable and the USB
sockets. After re-booting, the external drive starts, but it does
appears anymore in my file manager. I tried with a second portable USB
HD (also formatted Ext4). The lead turns green, but it does not
auto-mount either.
I tried with a USB stick (Fat32). I can see this drive in the file
manager.
How do I troubleshoot that?
If you get a light it probably means you've got power, but not
necessarily any other signals.
Stuff the thing in, and see what is logged in dmesg when you do so
