My old Gateway desktop crashed, is non-repairable, when I tried the harddrive into the newer Gateway, it came up blank blue screen......checking file system on G, CHKDSK verifying files.......& nothing came up on it, a computer tech at the store checked it, said it was working & had 16G on it,.........can I buy a backup device, & try to transfer it to the working computer on a new blank hard drive?
