| Logical Drives |
|
The internal division of a large hard disk into smaller units. One single physical drive may be organized into several logical drives for convenience; DOS supports up to 23 logical drives on a system. On a single-floppy system, the disk drives can function as both logical drive A and logical drive B, depending on the exact circumstances. A drive that has been created by the disk operating system (DOS). This is done either at the preference of the user or because the DOS version does not allow a formatted capacity in excess of 32MB. A user with a 100MB hard disk will want to use more than 32MB, so a program will tell DOS there are a bunch of "logical" drives that add up to 100MB. DOS 5.0 eliminates this need. |
