I lost approximately 680 GB of data on my Seagate 2TB hard drive while experimenting with a software called StorageCrypt. I used it a few months ago and today I tried it again. But, I didn't know that the old password is already set in the hard disk when I pressed the encrypt button.
I forgot the password which is disappointing. Not to mention, the software uses 128 bit AES encryption so there is no way that I am going to recover that data.
I want to completely erase the hard drive so it is just like it was when I first purchased it. Is it possible to format a hard drive which has been encrypted? I tried to format by right click, Format. But the size of the disk is shown as 1 MB.
