View Full Version : Can't create new partition

I have a 32GB MicroSDHC card with the following partitions:

a 286MB FAT32 EFI partition
a 15GB ext3 Linux partition
14GB of unallocated space

I want to create a partition in the unallocated space to share between Windows 8 and Linux. I have done this many times on my old laptop's HD, but I can't get it to work with this card.

When I open Disk Management as administrator and right-click the unallocated space, all options to create a new volume are greyed out. DISKPART says the operation is not supported on a non-empty removable disk. (These issues happen in both Windows 8 and Windows 7.)

In Linux I tried creating a new partition (either primary NTFS or FAT32), but Windows doesn't mount it. Disk Management can see the new partition but won't format it (fails with an unexpected error.) DISKPART considers the Linux partition and the new partition to both be Partition 0 and will only select the Linux partition.

Can someone offer any advice on this problem? Thanks!
