It always sucks to loose valuable data!
I take it that none was backed up. This is were I should be lecturing you about backups. But you've already suffered enough. And I've been in the same boat too.
I have about 6 hard drives that work right now, Usually I keep one or 2 just for my backups, the rest are for the day to day stuff, and for testing.
I can't help ya get your data back, But I can easily spare one HD for you so you'll have one just for backups. That'll help in the future, if you want. They ain't big ones, but plenty big enough for backing up data.
Also it might have helped if you'd partitioned the HD into 2 or more HD's. But if the data was already on in before you partition it, that data would get gone too.
Lemme know if you want one, I can ship it to you for $5 total, and it should be there in 3-4 days. I just got a package from Bill Wicklund, (PlumbBill). it only took 3 days.
Anyway, I feel your pain dude. learning can suck sometimes!
Don't let it get ya down.
