- ********************************************************************
- A simple program for IBM-PC to make full use of cleaning disks,
- such as those sold by 3M and Verbatim.
-
-
- Format of command:
-
- X>clean [drive:]
-
- If no drive is specified, CLEAN assumes you want to work on the
- default drive, else drive a:, b:, etc. When it is through you
- are asked if you want to clean any other drives, and if so
- prompts for the drive letter.
-
- This works on single or double sided or quad density drives
- without modification and naturally will not accomplish too much
- on your fixed disk. No harm will come, however, if it is run on
- your fixed or floppy disk as it uses the PC-DOS absolute sector
- READ to move the head around the disk.
-
- The reason you use a cleaning utility rather than using DIR or
- any other command to get the disk moving is that since the disk
- in the drive is paper, the head will never get past Track 0 where
- DOS goes for the directory in order to try to accomplish your
- command. In other words you will never use more than 2.5% of the
- surface of your cleaning disk. CLEAN knows there is a cleaning
- disk in the drive, ignores the DOS error message that the READ
- has failed, and tries to read another sector on another track.
- This way the head is moved about the disk and more effectively
- cleaned.
-
- Cleaning your disk drive is good preventive medicine, but don't
- overdo it. A drive that is in heavy use probably needs to be
- cleaned once a week, but on the average once every other month is
- plenty.
-
- The reason for the 2 in CLEAN2.COM is that this is the second
- version of this program. At the time I wrote CLEAN I only had
- single-sided drives and was not able to test CLEAN with
- double-sided. Thanks to a User Group Librarian I was set
- straight on this and have improved CLEAN. Users of the older
- version may remember a patch I had provided for working with DSDD
- drives. This patch was not needed. I am sorry for the
- inconvenience caused by this and present this better working
- version.
-
- CLEAN now times in closer to the recommended 30 seconds for
- cleaning a disk. It also uses a random factor to start its
- journey across the surface on different tracks. Since it uses
- only the most basic of MS-DOS functions, it should run on any
- MS-DOS computer.

- [At my request, Marty has modified the program so that it will
- work on any drive letter, so those of us with add-on quad disks
- can be next to godliness, too. Don't try sticking a cleaning
- disk in your RAM drive, though! R. Jueneman/SYSOP/(703) 237-4322]
