VDS returns the following when you select a partition format that it does not recognize:
C:\> Diskpart
DISKPART> list disk
DISKPART> select disk (id)
DISKPART> list part
DISKPART> select part (id)
Virtual Disk Service error:
The pack is not online.
The pack is not online error (VDS_E_PACK_OFFLINE 0x80042444L) is returned when Diskpart attempts to get the file system properties on, say, an ext3 or hfs+ file system. Diskpart works only with Fat and Ntfs file systems. If the goal is to delete the non-Microsoft partition, use the clean command.
DISKPART> list disk
DISKPART> select disk (id)
DISKPART> clean
