SUMMARY
The maximum number of logical drives that can be contained in an extended partition is 23. Thus, with an active MS-DOS partition, and all 23 logical drives (in the extended partition) allocated, this gives 24 hard-disk drives (23 + 1) that can be used, in conjunction with other virtual RAM drives, network drives, and floppy-disk drives. The maximum number of total drives that MS-DOS can use is 26: Drive A through Drive Z.
