My old laptop froze up while saving a document and corrupted it completely.
Not just any old document, mind; it was eight months' writing, lost in a split second.

Bugger
no chance of it being retrieved?

Nope.
First part was OK (and I had a backup copy of that) but as the rest of the file was completely blank there was nothing to recover.

On the plus side I've still got all the notes, and it was pretty rubbish and verbose anyway - now I can re-write it and make it better!

Bad luck that
glad at least some of it was saved.

I've been playing around with it for ages, but it looks like somewhere between converting it from about five different file formats the data has disappeared

Ouch.
Similar thing happened with my dissertation a few years back. Gut-ted. Fortunately, unlike the rest of my course work I hadn't started it at the last minute and was able to rewrite it with time to spare.
