    14 Also, you can use \\ .\Physical_Disk# or \\ .\w: to use raw filesystem option (disk is read via DosRead instead of DosDevIOCtl and opened without OPEN_FLAGS_DASD). But this doesn't work with current os2dasd.dmd. It will just trap in os2dasd trying to open \\ .\Physical_Disk# or give ERROR_LONGLOCK on DosRead at some point if opening \\ .\w:. IBM added this option without even checking if it works really. So, this needs os2dasd or others disk drivers to be repaired to be working. But this case is supported.

    16 Also, in windows, there exist the possibility to open \\ .\DiskNPartitionM, i.e., open partition by disk number and partition number, without assigned drive letter. We haven't such option on OS/2, so letting the VM to see a subset of a hard disk partitions (not a single partition and not all partitions) is currently impossible (If we will not try to convert M and N to a drive letter).
