However, when I check it's properties in Explorer, it shows as zero free space and zero used space.
If I try to save, say, a Word doc to it, I get 'The parameter is invalid'. If I try to change to the drive under DOS I get the same message, rather than 'Can't find drive specified' message which I would expect. I've tried a number of so-called disk recovery tools on it, all of which failed spectacularly.
So, I'm at a bit of a loss and looking for ideas...
Thanks...
