- This software is provided AS-IS. There is no warranty,
- either expressed or implied. The author is NOT responsible
- for damage either through use or misuse of this program.
-
- INTRODUCTION
- ============
- DDPC is a utility that will park the heads of ALL hard
- drives installed in a system (up to 32,727). DDPC includes
- such features as:
-
- * An "info" mode that gives the BIOS' view of your hard
- drive.
-
- * A "single park" mode that lets you park a single (or more)
- drives and continue working on another.
-
- * A "windowed screen saver" so that you can park you drives
- and leave the computer on. DDPC will display a moving
- window on the screen so that it will not burn in. It also
- informs anyone looking at the screen that the computer is
- not off, but rather is idle.
-
- DDPC version 2.50 is a complete rewrite from version 2.3.
- The major addition is the bouncing window in the screen
- saver mode. The screen save should work on all video
- systems using 80 columns.
- The single park mode has changed from version 2.3.
- Instead of giving DDPC the MS-DOS names, you give the
- "physical number" of the drive. This was to ensure that you
- don't try to park some "partitions" that are not physical
- drives. Refer to the section SINGLE PARK MODE for details.
-
- GENERAL SYNTAX
- ==============
- DDPC works like this:
-
- DDPC [/Clear] [/Status] [/Info] [U#]
-
- Arguments in the square brackets are optional. If DDPC is
- run with no command line arguments, it will park all hard
- drives and wait for the <ENTER> key to be pressed. When
- ENTER is pressed, DDPC will drop back to MS-DOS. After,
- DDPC displays that message, the drive is safe to turn off.
- To display the help screen, run DDPC /?.
-
- CLEAR MODE
- ==========
- The "clear" mode is DDPC's screen saver. When run this
- way, DDPC will park all the hard drives, and display a
- bouncing window. Anytime, you can press any key and DDPC
- will drop back to MS-DOS.
- The "clear" mode should work with any display adapter that
- uses an 80 column text mode. If the screen mode is NOT 80
- columns, DDPC will abort with an error message.
- The "clear" switch can be shortened to /C.
-
- STATUS MODE
- ===========
- Status mode is similar to running DDPC with no command
- line arguments. However, it displays information about the
- drives as it parks them. It is mainly for curiosity's sake.
- The Status mode can be shortened to /S.
-
- INFO MODE
- =========
- The information mode displays the information about each
- physical drive as reported by the BIOS. It displays the
- number of heads, cylinders, and the sectors per track.
- Then, it makes a guess at the size of the hard disc. NOTE:
- if the size that DDPC estimates is MUCH different from
- yours, then the controller is lying to the BIOS. Some hard
- disc controller do this. It is nothing to worry about.
- The Info mode can be shortened to /I.
-
- SINGLE PARK MODE
- ================
- The single park mode is for parking, say, a second drive
- while still using the first. In a prior version of DDPC,
- the MS-DOS drive letter could be used to specify which
- single drive to park. This has been removed. Instead, the
- drive is specified by its BIOS unit number. The first hard
- drive (usually C) is unit 0, or U0.
- For example, if two hard drives are installed, the second
- can be parked like this:
-
- DDPC U1
-
- DDPC will park unit 1 and exit back to MS-DOS. If an
- error occurred, DDPC will inform you.
-
- INTO THE FUTURE
- ===============
- What is to come? I was considering adding a time display
- to the bouncing window. Changing the amount of delay would
- also be added.
