It's just a storage drive but windows stopped recognising it as being an ntfs partition.
I tried using Piriform recuva but it would seem that the reason that explorer crashed in the first place was because I opened a file that was on a bad sector of the disk. Because of this fault, no scan I tried with any application got past 2% without hanging.
I'm now several hours into trying to recover a disk image with ddrescue in ubuntu rescue remix. Hopefully once it's done I'll be able to use recuva, photorec or somethign similar to get my stuff back.
All in the best case scenario is that I have to buy a new storage device during this current price increase with the worst being I lose all my data.
It's a good thing my housemate has 2 spare 1TB harddives lying about that allow me to use ddrescue properly.
If anyone has any better suggestion for recovering the files I'm all ears but it will have to wait until ddrescue is finished and my new drive arrives!
