Problem formatting external disk

[Billzz]

Hi all,

I’m having some trouble with formatting an external disk. The disk is a WD Red 4TB which I currently have housed in a Akasa Black S USB 3.0 box.

The problem is when going to format the disk, it is showing as two *physical* disks - (this is in both OS X and Windows). The disk sizes are 2048 for disk 1 and 1678 for disk 2.

The disk itself was from a WD iCloud unit which I took apart because the iCloud unit was so bad - (avoid if you get the chance).

I cannot get this drive to partition as one drive - could there be 'special' firmware on the disk that makes it work as 2 separate disks? Anybody any ideas?

Thanks for any replies.

I can try but I'm also going to try another enclosure to see if the same thing happens.

Hi Borealis,

Thanks for the reply. I have tried reinitialising both 'drives' in OS X using GUID but it didn't make any difference - I still cannot partition as one drive afterwards.
