-	[ 20] UINT32 compression;	// compression type
-	[ 24] UINT32 blocksize;		// sectors per block
-	[ 28] UINT32 totalblocks;	// total # of block represented
-	[ 32] UINT32 cylinders;		// number of cylinders on hard disk
-	[ 36] UINT32 heads;			// number of heads on hard disk

-	[ 60] UINT8  parentmd5[16];	// MD5 checksum for parent drive
-	[ 76] (header length)
-
-	Flags:
-		0x00000001 - set if this drive has a parent
-		0x00000002 - set if this drive allows writes
