- Why would you, the customer, want to change the interleave value? When the
- computer manufacturer initialized the computer system, there was no tape drive
- installed as there is now. The tape drive, when operating, uses the computer's
- memory at almost the exact same time as the hard disk does. This causes the
- computer to not be able to supply or accept data from the hard disk as fast as
- it would when the tape drive is not running. (Note: you may or may not have a
- tape drive installed, depending on where you got this program).
-
- Note: The tape has to actually be moving before it slows down your system,
- don't worry!
-
- An easy way to see if you need to adjust your interleave is by running your
- tape backup program, and performing an IMAGE BACKUP. Listen to the tape drive
- as the program runs. If the tape runs for a long time before stopping, your
- computer is probably just fine the way it is. If the drive stops for a moment
- every 5 to 15 seconds, you probably need to change the interleave.
-
- By increasing the interleave from the factory value (usually 2, or 3) your
- computer will be able to handle the requirements of having two high-speed
- devices being used at the same time, instead of just one.
-
- Our tests have shown that a good value for interleave is FIVE. This should
- give you nearly identical performance with your other programs (spreadsheets,
- BASIC, and so on), but will help the tape drive to receive and transmit in a
- smooth, streaming manner.
-
- If you want to select a different interleave value, you specify it on the
- command line, such as IAU 3 <cr>. Permissable values are from 1 to 15.
- Typical values are from 2 to 6.
-
- This interleave-changing program is specially designed so that none of the data
- you have on your disk will be altered during the operation. All of the
- programs that we had seen wipe out the data on the disk whenever the interleave
- value is changed. That's why we wrote this program for our customers.
-
- Please be sure to read the WARNING MESSAGE before you start the re-interleave
- operation.
