Thanks hang-the-9 for the reply.
I have not used key to encrypt, only a password. TrueCrypt allows encrypt with password, key or both. I selected password only. So if i can get partition as before, accessing with TrueCrypt won't be a problem.
On dos, we could do unformat for just format, here, i deleted partition, created new and formatted it.
The issue you will run into is that when you encrypt a file, to the regular operating system the file looks like junk. So when you run the recovery software to try to peice together the deleted files, it will not see the file fragments properly, and instead of getting the encrypted files you will get back a ton of unencrypted junk data. Recuva can restore the partition and scan for files, but who knows what you will get.
Unless for some reason when you secure with TrueCrypt it does not encrypt the data but rather just password protects the container. That may be good news. You should check with the TrueCrypt forums and see what info is there.
