Just a thought ....

Have you ever run fsck on your ext drive ?  There is a tendency for
users of USB drives to plug them in for backup *after* booting, so they
don't get fsck run automatically on them during the boot process.

Boot into admin mode from your distro boot media, and run:

	fsck /dev/<usb-device-partition>

Where usb-device-partition is the actual device name of your partition.

Depending on your file system, (ext3, reiserfs etc) you may need to add
other options.
