My Western Digital My World Book White Light NAS Drive stopped working. This has a single 1TB Disk.
At first I started getting the following error: Volume Status - Volume 'DataVolume' doesn't exist
Then the NAS refused to boot.
So I've removed the disk from the NAS and connected it to my Ubuntu laptop using a SATA to USB Cable.
Running TestDisk returns this :

When I run testdisk the results table shows all the entries with a D in front of them, apart from the last one which has aP
I've done a deeper scan, that took all day..
and this is the result :
Disk /dev/sdb - 1000 GB / 931 GiB - CHS 121601 255 63
Check the harddisk size: HD jumpers settings, BIOS detection...
The harddisk (1000 GB / 931 GiB) seems too small! (< 1965 GB / 1830 GiB)
The following partitions can't be recovered:
MS Data 67319776 2014370271 1947050496
XFS 6.2+ - bitmap version, 996 GB / 928 GiB
MS Data 128165104 2075215599 1947050496
XFS 6.2+ - bitmap version, 996 GB / 928 GiB
Mac HFS 128167720 2074956007 1946788288
HFSX, 996 GB / 928 GiB
Mac HFS 128190436 2074978723 1946788288
This goes on for thousands of lines........
Could someone please advise what this means and more importantly if my data is recoverable and how ??
Many Thanks
