Here's what's happened. I have a PS3. The other day I decided to do a back up. I haven't backed up a ps3 harddrive before, so I thought I'd do it through the PC instead of the PS3 (I've backed up many harddrives on my PC before, so I thought this was a clever thing to do)
I plugged it in and went to disk management, and clicked Initialize. Bad idea... The PS3 harddrive is in some weird format... like a modified version of FAT32, and when I clicked initialize, it did something to the table structure I believe.
Anyway, after initializing, I realised i had no way of copying the files over, so I took it out.
When I plugged in the harddrive into the PS3 and turned it on I was greeted with the unwelcome message "The harddrive needs to be formatted, blah blah blah"
Now I want to clarify that all I did was click Initialize... a tenth of a second later it was done. It couldn't have done anything TOO harmful, but after a day of trying a handful harddrive recovery softwares, and scouring the net, it appears what I'm trying to do is fix the unfixable.
PLEASE just tell me how I can UN-initialize the harddrive somehow or get my important data off... It just seems ridiculous that a single non-descriptive button can ruin a harddrive in less than a second.
