External hdd not reading properly

[fast_motion]

So the issue is that the hdd appears in my computer but only as a local disk, it doesn't show any used space like it should normally and when I access it it says the folder is empty.

I've tried that disk management and changed volume letter two times to no effect and I've also tried to go in device manager and delete the usb mass storage driver and it had no problem reinstalling it again but to no effect.

I was wondering if it would help with a quick format but that would mean losing 1tb of stuff I have there... is there anyway I can get it to work without having to lose anything ??

What is the actual size of the drive you're trying to access?
If it's over 2.2 Tb the BIOS will not be able to access it!
see my post over -here-

The initial size is 3tb but I had no problems with it before. I was on holiday and took it with me for 2 weeks and when I got back home it wouldn't work anymore...
