SYMPTOMS
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.



CAUSE
Mount Manager assigns drive letters to recognized partitions even if they are not formatted so that you can issue a format : command. However, this behavior may cause all drive letters to be assigned automatically if there are many partitions.
