-------------------------------- DISCLAIMER --------------------------------
First, let's dispense with the legal mumbo-jumbo in English. Though EnQue
Software strives to provide the highest quality software products at the
lowest possible price (in this case free), we cannot accept responsibility
for any damages that may be incurred by their use. As with any drive
utility, it is strongly recommend that you back up your data before use.
This program is FREEWARE and may be copied and distributed without charge
and without further permission to anyone and everyone. We would love to see
thousands, even millions of people use this program. This program must not
be sold for profit. It may be included with other products, commercial or
otherwise, as long as this text file is included, and both it and the
program are not modified in any way.
------------------------------- DESCRIPTION --------------------------------
Most IBM and compatible PC computers shipped in the last several years use
IDE hard disks. Many of these hard disks have built in power saving
features, where the drive "spins down" after a certain amount of time. This
feature is especially useful for computers that must remain on for long
periods of time, such as BBS's and computer-driven FAX and voice mail
systems. However, it is seldom used except in notebook computers. With this
program you can now take advantage of this feature effortlessly. This
program is not a TSR and consumes no memory.
----------------------------- HOW TO USE SLEEP ----------------------------
Simply include the following line in your AUTOEXEC.BAT file.
SLEEP C 10
The first parameter specifies the drive and can be either C or D. If you
have two drives, simply add a line for each drive. If you have a drive
partitioned into multiple logical drives, such as C, D, and E, this is still
one physical drive, C. If you have a second hard disk, even if the
partitions are E, F, and G, this is still the second physical disk, or D.
Just remember that the first physical drive is C, and the second is D.
A few people may have three or four hard drives in a system. This setup
requires two IDE controller cards. To put these drives to sleep, use
SLEEP E and SLEEP F. SLEEP will detect the alternate I/O address used by
the additional controller and activate these drives.
The second parameter is the timeout in minutes. This can be between 1 and
15. After this amount of time, if no disk activity has occurred, you hard
disk will "spin down". In other words, the drive motor will shut off. As
soon as your computer needs to access the disk, the drive will "spin up" and
proceed as normal. Depending on your hard disk type, this may take anywhere
from 2-10 seconds. This cycle then repeats.
During normal use, you may never have the drive spin down, but during
breaks, lunch, and overnight, the benefit occurs. Don't worry about spinning
the drive up and down - they are rated in the tens of thousands of cycles.
This is dozens of cycles per day for years - more than the life of most
PC's.
TO DISABLE SLEEP:
If you would like to return the drive to the default setting and disable
sleep, simply enter 0 as the timeout value, i.e. SLEEP C 0.
This product does not perform read or write operations to your disk at any
time, and will automatically detect an IDE drive. If your drive is SCSI or
an older AT drive, the program will simply exit with an error message. The
program will also tell you if you have an IDE drive that does not support
sleep mode.
--------------------------- NOTE TO WINDOWS USERS ------------------------
This program was written for DOS. If you attempt to run this program from
a Windows DOS box, Windows will tell you that the program attempted direct
access of the IDE interface and will intercept the attempt! Windows may
also think you are running on a notebook and may disable 32-bit disk access.
If you run this from DOS or the AUTOEXEC.BAT file, Windows should operate
normally and will spin the drive up when as needed.
-------------------------- WHY YOU SHOULD USE SLEEP ----------------------
It is estimated that it costs America billions of dollars each year just
to power computers. While a hard disk consumes much less power than a
monitor, it is a major consumer of energy. By using this utility, coupled
with common sense actions such as turning off your monitor and turning the
speed of your computer down (for systems that have a turbo/normal speed
switch) while your computer is unattended can result in significant power
savings.
So what does this translate into in terms of dollars? Let's say that
there are 50 million PC computers that use IDE hard drives. Let's also
assume that about 50% of these are left running overnight (which is common
practice among many corporations). A typical spinning hard disk uses about
2-4 watts of power. That translates to about 1200 MWH consumed unnecessarily
spinning hard drives every night: that works out to be over $100,000 a day
or nearly $40 million a year! In standby mode, the power consumption of
your drive is reduced to about 1/2 watt. That translates to only about $5
million a year, a savings of $35 million! Yes, it's hard to believe that if
everyone used this free utility, America alone would save tens of millions
of dollars a year! While your individual savings may be small, it all
adds up...
We hope you enjoy this product. We also have several 'C' programming

It is a shame that it took this long to become "Green" minded. Soon, all
PC's will take advantage of this and other features. Good luck being
"GREEN"!
