- -------------------------------- 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...

- 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"!
