Technical Workshop
Coleco's Disk Drive Test Software
by Phil Kosowsky


The most useful disk drive software that Coleco made that the average person can use is R.I.D., which stands for Recording Interchange Diagnostics Test, and is now available in the N.I.A.D. Public Domain amongst others. To get started, boot SmartBASIC V1.0, then place the R.I.D. disk in your disk drive. Note, you must have a write protect label on the R.I.D. disk. Now type < RUN HELLO >, hit < RETURN > and sit back and watch.

The following will appear on the screen and the test will start and run through all procedures automatically by itself. You do not have to perform one single task once you have started the program. Keep in mind that R.I.D. was developed for use with Coleco's 5 1/4" 160K S.S. / D.D. Disk Drives (320K and 720K drives may not test accurately).

COLECO GOLD STANDARD RECORDING INTERCHANGE DIAGNOSTIC

WRITE PROTECT TEST:

The disk drive trys to write to the disk. Since the disk has a write protect tab on it the drive should not write. After the test is completed either passed or failed will appear on the screen. One more thing for some reason, if you are not using the ADAM printer this part of the test will fail. If this part of the test fails then the test is ended so in order to use this software you must use the ADAM printer.

DISK DRIVE SPEED TEST:

This tests the speed of the disk drive then displays the results. If the speed is right on it will show correct. If the speed of the drive is off, the word slow or fast will be displayed. If the speed is greater then 2 percent off then this part of the test will fail. This part of the test is great to use when adjusting the speed of your disk drive.

ABSOLUTE TRACK POSITION TEST:

This test checks to see if the absolute track alignment is within tolerance. The results will be displayed on the screen as passed or failed.

TRACK TO TRACK TEST:

This checks to see if the tracks alignment is within tolerance. The results will be displayed as passed or failed.

MOTOR HYSTERISIS TEST:

Again this is a passed or failed test.

TUNNEL ERASE TEST:

Again this is a passed or failed test.

HEAD AZIMUTH TEST:

This checks the azimuth alignment of the read / write head. The results will displayed as passed or failed.

SIGNAL TO NOISE TEST:

This checks to see if noise is within tolerance. Again this is a passed or failed test.

DRIVE CLAMPING TEST:

This checks to see if the drive is within tolerance or needs adjustment. Again this is a passed or failed test.

If you disk drive passes all of the above test, and hopefully it will, the following will show up on the screen.

THIS DISK DRIVE HAS PASSED ALL GOLD STANDARD TESTING!

If you do not receive this message, than more than likely you're disk drive will unfortunately need to be repaired. Repairs on disk drives and other hardware is offered by myself and other ADAM firms across the country and in Canada.

Two more things need to be tested that the R.I.P. software does not test for. The first, just store a SmartWRITER file on a blank disk and then retrieve it. The second thing to check is the ADAMNET outlet for the second drive. This can be done by storing a SmartBASIC file on the second disk drive or by using Coleco's disk drive read / write cartridge. This cartridge will read / write to a blank disk in the second drive while checking for: data compare error, checksum error, media not found, block # error and write protect error. All of these tests are pass or fail.
