Partitions in Windows 8

I have windows 8 64 bit and I have My Passport

The problem is that when I connect my hard drive to windows 8, it shows only 1 partition where as I can not see  the other partitions I have created. I can view all the partitions in windows 7 but not in windows 8.

I have changed the drive letters from disk management and it solves the problem temporary but not permanently.

Please help in this matter.

Are you still having issues with Windows 8?
