Why does this happen only to 3TB HDD & not to the 2TB ?

post #1 of 7
Thread Starter 
Okay heres the backstory, I bought a 3TB HDD a little while ago for storage I'm still playing around for now until I'm ready to store files on it. So this is what happened. I got a Deskstar 3tb internal new and I formated using GPT format NTFS with ext dock. I put some files on the 3tb and I'm using it with esata thermaltake ext dock. All is good, but then I tried the 3tb in my other ext dock it's a rosewill 3.0 USB. For some reason the dock/pc was treating it like it was the first time I used the HDD, it did not see the files nor even see the 3tb in my computer. So I went to start computer/manage/disk managment then I was prompted to format the HDD like it was new again so I did it again chose GPT format assigned a new letter again, then format again. I have no choice I have to format to see the drive. So obviously I lose the data on the disk, which sucks. If I go back to the thermaltake but I formatted with the rosewill dock first same thing again. Thermaltake/pc won't see the 3TB drive have to format/GPT again. So both docks are doing the same thing to each other.

When I do this with the 2TB no problems I can switch back and fourth from the diff ext docks no reformatting works great. I formatted the 2TB orginally with the MBR format by the way.

Is this happening because I'm formatting using the GPT format ? My board is a UEFI BIOS so if I were to use MBR format instead of GPT would that fix this problem ? If I have UEFI BIOS should I even be using GPT ?

I currently don't have the 3TB with me anymore. So I can't test things. But I was thinking of buying another one but wanted to to see if anybody here knows what was causing my problem. If I can't get a firm answer I'll just buy another 2TB.

thanks

Yes, it's because it's GPT format. You could format it MBR, but due to the volume size limitations on MBR it will have to be at least two separate volumes.

Sounds like the docks don't like each other/have issues with 3TB drives.

When you say ''two separate volumes'' do you mean two separate partitions formatted to MBR on a single 3TB or two HDD I'm confused ?

I thought with UEFI BIOS you can use MBR format with a 3tb HDD. I thought UEFI BIOS was not suppose to not have that 2.2TB limitations and not have to use GPT.

So even with a UEFI BIOS mobo and a 3tb HDD you have to use GPT format ?

These ext docks were kinda new and were comfirmed by others to work with a 3TB hdd.

Yes, two separate partitions. I also have a UEFI bios, but my 3TB drive would only work in the way I described. I ended up using GPT.

So lets say I decide to not use ext docks anymore and just install the GPT format 3tb hdd in my case and it's fine and one day I decide to migrate to another board and when I hookup the 3tb again inside the case but with a diff board I won't have that previous problem that I had with the diff ext docks right ? Cause if I get a new board and I have to format my 3tb again so it works with the new board then I'll lose everything on the 3tb.

So basicly I should never have my orginal problem with using a GPT 3tb hdd within the pc case even if I change my mobo ? Hopefully this problem specifically is only with the docks.

I believe it is just the docks. I've not had that issue myself going from PC to PC.
