Windows 2000 automatically assigns drive letters to all partitions, including partitions that are in raw format (partitions that have not been formatted). This can cause a problem if there are many partitions because Windows 2000 may run out of drive letters to assign. Some programs use raw partitions; assigning drive letters in this case is not required or appropriate.
Mount Manager assigns drive letters to recognized partitions even if they are not formatted so that you can issue a format drive_letter: command. However, this behavior may cause all drive letters to be assigned automatically if there are many partitions.
