Creating Many Partitions Causes Double Drive Letters (175266)

SYMPTOMS

If the system has more partitions created than there are available drive letters, after you start Windows NT, some partitions may have more than one associated drive letter.

For example, if 40 logical partitions are created using Disk Administrator, after restarting Windows NT, both C: and D: are assigned to Device\Harddisk0\Partition1. Drive letter assignments may vary from case to case.

The reason why the user needs more logical partitions than the number of available drive letters is for Oracle databases. Oracle databases can treat logical partitions without drive letters.

If another logical drive is created after using all available drive letters, Disk Administrator will display the following message:

All available drive letters are already assigned. You will not be able
to access the <drive letter> from Windows NT unless you rearrange drive
letter usage.

Do you want to continue and create the <drive letter> anyway?
