I recently bought an external hard drive case for a laptop hard drive so that I could use it as a backup for my files. Upon putting the hard drive in the case and plugging the case into the computer, the hard drive was recognized and I then started to format the drive before going to sleep. The next morning I wake up to find that the computer froze in the middle of formatting the drive and now the drive is no longer recognized by my computer or any other computer for that matter. Is there anything I can do to resolve this problem? Thanks in advance.
