- This page gives various information about the current drive, as given by
- DOS.
-
- LASTDRIVE is the letter typically given as the LASTDRIVE= command from
- your CONFIG.SYS. The default is E, unless you have more than 5 drives
- defined, including floppies (a single floppy counts as 2), hard drives
- (each partition is one letter), special drivers (such as Stacker or
- Diskreet), and RAMdisks. Specifying extra letters allows you to use the
- SUBST command effectively.
-
- Logical drives are real drives, those created by the SUBST command, and
- those created by special drivers.
-
- The settings shown for the Diskette drives is for the last used floppy.
- If a floppy has not been used since the last reboot, the data shown may not
- be valid.
-
- For the current drive, the drive type may not always be correct. There is
- no standard way of telling if a drive is actually a RAMdisk or similar.
-
- A door lock is used by high density drives to let DOS know if a floppy
- has been removed. Some removable hard drives may also use this.
-
- JOIN lets a drive act as if it was a subdirectory of another disk.
-
- SUBST lets a subdirectory act as if it was a separate drive.
-
- A cluster is what DOS uses to keep track of data on the disk. A cluster
- consists of several actual sectors of data. A standard hard disk will have
- 4 sectors in each cluster (2K of data.)
