I was encouraged to repost this here by the storage forum: I have a terabyte full of stuff, and I recently went to open a directory via a shortcut and was informed that the drive path did not exist. I opened Computer and saw the drive wasn't listed there. Assuming it had somehow lost connectivity, I switched the drive off, waited for a few seconds and turned it back on again. This has solved this problem when I've discovered 'missing' drives in the past. However, when I switched the drive back on I discovered that it was completely 'erased'. Nothing is on the drive, and that is confirmed by Computer's space analysis. This is mildly disturbing. What happened to all my stuff?
