New data disappeared without overwriting old data.

I have a 2 TB Seagate External drive that I use for backing up images of two computers using Acronis True Image. At one time recently, it became completely full and unusable. I used TestDisk to get some files off of it and reformatted it. I started using it again and limited the number of backup versions so it wouldn't get full. A couple days ago, it became a RAW drive with 1MB Unallocated.
There are two selections for the same drive when trying to select a media in TestDisk:
Disk /dev/sdb - 2000 GB / 1863 GiB
&
Drive H: - 2000 GB / 1863 GiB
Choosing Drive H:, the partition table screen defaults to [None} Non partitioned media. Analysing the drive just keeps getting read errors. It has been 24 hours and it is only 12% finished. I also can't stop it without closing the command prompt window completely. TestDisk is unresponsive to the Q key. When I tried looking at the file system, I got a message that the File System seems damaged.
When I used TestDisk to find lost partitions on the Disk /dev/sdb selection, it found previous partitions that should have been overwritten by the backups. The backups are not on the drive. How is that possible? I don't mind reformatting it again if I need to, but I'd rather get the backups back. How can they have just disappeared without a trace and without overwriting previous data?
