Well, as it turns out, I accidentally clicked on the incorrect HD icon and quick formatted
the wrong HD. I thought I was formatting my new 3TB HD and it turns out I quick formatted my old HD -
So I thought everything just went, PFFFFFF!!!! all gone. But then a friend asked me if I only quick formatted and hadn't tried to write anything new to the drive, and I said yes, this was the case. So he took my HD home and did something to it to "retrieve" some of the files. He said it had something to do with the quick formatting process changing the directory to a bunch or zeroes or ones so that my computer would think the drive had been wiped out but in actuality the data was supposed to still be there.
I just looked at the "retrieved" HD and while there's some things I can access again (and almost all of the files names are gone so I'll have to rename everything, a gargantuan task), it seems quite a bit (I don't recall how many gigs of music and photos there were, but quite a lot) is not there.
So this all leads up to my question: is there a utility of some sort (now that I know this is possible) to get more of my files back - or is it probable that whatever my friend did to my drive may have precluded this possibility?
