listing volumes on a disk

NTDEV
1

Apologies for off topic question.
Felt more likely to find help here.

I am listing out all the volumes on a disk with

FindFirstVolume();
while( success )
FindNextVolume();
FindVolumeClose();

This is working fine and I am getting all the three
volumes if my disk layout is

NTFS(PartitionStyle = 0x7)
NTFS(PartitionStyle = 0x7)
RAW(PartitionStyle = 0x27)

but if changed to

NTFS(PartitionStyle = 0x7)
NTFS(PartitionStyle = 0x7)
RAW(PartitionStyle = 0x28)

I am getting only 2 NTFS volumes. The other partition
is missing.

Any ideas why?

Thank you.
V.

Volume APIs (which are wrappers around IOCTLs to MountMgr.sys) and the
underlying MountMgr just plain ignore partitions whose MBR type byte is non
FAT and non-NTFS.
