Also I tried it with another old HDD and the same happened. The partition was lost when connected to the caddy. Then I had to re-partition the drive after which it worked fine. Clearly the LaCie caddy is for some reason stripping the partition data off the drives so they look unformatted/unitilaized by Windows. The drives still work fine themselves. Also yes I found the TC mode in VC.

As an external using a SATA to a USB connector. The HDD was loose as it were. I tried sticking it into an old LaCie "Big Disk Quadra" caddy and that's when the partition vanished. The partition now no longer shows up no matter if it's in the big disk caddy or not

No VeraCrypt cant get it either.

Thanks for the reply! I'll give Veracrypt a try but it used to be that TrueCyrpt would see "Harddisk 2" and then below that it would see a partition which would be what I mounted. It also used to be the case that Windows would say "The dive you just connected needs to be formatted..." when I connected the disk but it no longer says anything.

I have an external HD that I've got all my backups on. I plugged the drive into an old HDD enclosure I had lying around and the enclosure seems to have removed the partitioning from the drive. When I plug it in Windows (10) recognises the drive in Disk Management but thinks the drive is "unallocated" I've had a little look with hex editor (which I don't really understand atm) and I can see data on the drive after an initial load of 00000. Is there a way to get the partition back so TrueCrypt can unlock the data or do I have to accept the loss of my data? Thank you for your help!
