Ok, I've been trying to solve this problem for over week now and can't get anywhere.

I have a 3tb seagate expansion drive, which, a few weeks ago experienced an overvoltage, it ceased to work, but having broken a 1tb hard drive before I had an enclosure, so I moved the 3tb into the enclosure, hooked it up & formatted it. As it turns out, the enclosure was not 3tb compatible and therefore in disk management the hdd only reads 746gb.

I have since purchased a sata dock, compatible with all hdd sizes, when the hdd is in this dock, the drive does not appear in disk management whatsoever. But 3rd party programs(seagate discwizard,testdisk,AOMEI partition assistant.....etc) recognise it.

So basically, I've now got a 3tb hdd that I can use as a 746gb drive in one enclosure, but which should work in a dock I've got, but isn't.

When looking in the BIOS I see that there is a 2nd SATA (1st being the internal OS hdd) entry, but it shows no size...etc

Has anyone any idea how I can get my pc to recognise the full 3tb of disk space?

Thanks in advance, and I'll be more than happy to provide any more info!,
 
Your original Seagate enclosure was configured with 4KB LBAs for reasons of compatibility with Windows XP. Your dock exposes the drive's 512-byte LBAs, which means that your original file system will not be visible to your OS. However, data recovery software such as R-Studio will probably see your files. I'm betting that your other software will see a 349GB partition (= 3TB / 8) instead of the original 3TB.

If you can upload detailed photos of your original enclosure, there may be an easy DIY fix.
