Program Description:
-------------------

SCSI TESTER was written for the purpose of exercising your hard drives,
your SCSI controller, your SCSI cabling and more.


Program Requirements:
--------------------
  
For the program to work your SCSI controller must support CBM's RDB 
and SCSI-DIRECT commands. 
The GVP, CBM, and most other controllers support these.

KickStart and WB 2.04+ are REQUIRED for this program to run.
If you try to start the program on any system with LESS than version
37+ of the system libraries it will just exit.

The program may be started via the CLI or from WorkBench with the provided
icon. 


Program Operation:
-----------------
  
What the program does is to do a physical test of each and every block 
on your hard drive and to report any errors. 
It will, using scsi-direct commands, read a block of data, then move 
the heads, then re-read the same block of data and then do a compare 
of that data block in memory.
The amount of head movement between data reads is controlled by the
Gadget labled "Test Intensity". The details of that gadget are as follows:

NOHEAD --> Does NOT do any head seeks between disk read compares.
NORMAL --> Does 1 seek between disk read compares.
HEAVY1 --> Does 3 seeks between disk read compares.
HEAVY2 --> Does 15 seeks between disk read compares.

This gadget is activated for the entire run of the program and you may
toggle it as you wish DURING any operation.


  
This program is NON-DESTRUCTIVE and only performs reads to the 
particlar SCSI device ID. However, I do NOT do a lock on the 
partitions on the particular SCSI device being tested right now, so it 
would be suggested that this be run without any other disk access to 
that particular device. 

The CANCEL gadget may be hit at any time during the run with no ill
effects to anything. All you will have done is to verify the blocks up to
the point you hit cancel.


  
I have tested the program extensively on my system with a PP&S 68040
equipped A2000 with a GVP Series II hard card and three hard drives, 
(Quantum 40Q, Seagate ST296N, and a Maxtor 213SY),
and have not experienced any bugs, however, I'd like to get
it tested on a few more machines before I release it to the world out of
beta testing. I'd like to see some test results from machines with
multiple controllers with multiple drives also. This will ensure that the
SCSI ID, BOARD, and LUN gadgets are working correctly.
  
Any suggestions you may have for enhancements to the program or bug
reports would be appreciated..

Let me know what you think....
