I really tried to do everyhting right. I backed up all my data onto an external drive - and then the external drive broke. I just reformatted using quick mode and I was told it was possible to retrieve my data if quick mode was used. Can someone explain to me how to do this? Thanks.

Thanks for the suggestion. I will try it but I am afraqid the problem is more complex. You see, the files I need to get were encrypted and I don't have the codes for the encryption, so I think I need to roll back the entire reformat - not just recover files. Is this possible?

Okay, I ran Recuva and I can get most of my stuff back, but that's not the issue. The issue is that many of the files are encrypted (because I'm an idiot) and I need to be able to unencrypt them. Two questions:

1. Is the encryption information recoverable? If so where is it?
2. If it's not, can I completely roll back the reformat?

Thanks

Did you back up the keys you made when you encrypted the files?

No. would that information be anywhere in the system files? If it isn't, is there a way to unformat?

You can regain your data, but without those keys all that data is gone. Never encrypt anything you may want to recover later on. There is no reason to encrypt files unless you are on a public computer with a user account.

Does that mean it is not possible to undo the reformat?

It means...you may possibly recover the files...but, unless you know the key used to encrypt them...the files will be useless, since you cannot de-crypt them.

It is not possible to "undo" a reformat.
