Re: Need help ASAP with Abiword document recovery.
Yikes, that's tough... the problem with the external drives is that if they aren't unmounted properly (as in a hard reboot, or pulling the cord), recent changes are sometimes not written to the disk permanently yet. The drive holds a cache and then writes when there is enough to justify it, or it gets a signal to unmount. If it did that, you might have lost the autosave copy.
EDIT: Your computer spontaneously restarted? That sounds like a hardware issue, or perhaps a power fluctuation.
