BUP Slim Mac SL Drive

[Techforce]

Checking out this drive for a friend to see if I can perform a data recovery, they claim the
drive isnt detected in the Apple device they plug it into.

I tried it in my Windows Desktop, and it installed driver software, finished
, said its ready for use, but
no drive letter was assigned to it in explorer.

I had Seatools already installed, and it does find the drive as a "BUP Slim
Mac SL". Here is a a screenshot of the info
results:

I tried a short drive self test which works and passes. In the main window
of Seatools, it lists the drive status as "identify". there was another
short type test, which is passed, and it also passed the long test.

Found Testdisk, and ran the 64 bit version with success. The tests
I did seemed to say the partition cant be recovered, and when I checked each partition for files,
none showed.

During a deep scan of sectors a warning said: Warning: number of sectors per track mismatches 32 (FAT) != 63 (HD)
after it completed the long long sector scan, (which took about 4 days) this was the readout:

===============================================================================
The harddisk (1000 GB / 931 GiB) seems too small! (< 1999 GB / 1862 GiB)
Check the harddisk size: HD jumper settings, BIOS detection...

The following partition can't be recovered:

There are no jumpers on the drive, Its gotta be a SSD I am figuring as all it has is a USB cable, no seperate power cable.

After I continued this is where it displays lots of partitions:

Another place I ran this by said since the ending numbers are all the same, there has been maybe some corruption
in the allocation map for the drive, but the previous test claims no recovery is possible but that partition does not seem
to match any of the ones listed, so am stumped.

Testdisk docs seem to say that you can copy a partition from the drive, even though its corrupted, and try some way to
recover it on another drive, not sure?

I did go back and see where you can attempt a geometry change on the drive, but at a very high risk of corruption that can never
be fixed.. Not really any experience with Apple formats for drives here - any guidance appreciated.

Windows doesn't know how to read HFS+ filesystem.
It's better to check the disk from a Mac.
