What value should MaxTransfer be ?
To get your system up and running as quickly as possible set you MaxTransfer value using the following instructions :-
It must also be divisible by the sector size (512) due to a bug in the WorkBench format code.
Please test your set up by copying large files and testing that they were copied correctly. A large LHA file is a good test. You can test the archive after the copy to chaeck that all went well. I have heard of a SCSI disk on an A2091 card that would only work with small values. If in doubt use 0xFE00.
I will not give "optimal" values here. These values will get you going. If you want every once of speed you can increase the value until you get errors and the drop to the previous value. Use powers of 2 less the size of a block (512). Any speed increase will be VERY small and possibly not worth the risk.
