I ran the SCSICNTL.EXE program to examine my CDC Wren IV (hooked up
to an Adaptec 1542b), and have some questions about the appropriate 
settings.  The system is running Esix Rev D (SYSVR3 Unix).

Parameters:

                       Defaults      Current     Options

Disable Correction     enabled       enabled
Transfer on error      enabled       enabled
post error             disabled      disabled
early error correction disabled      disabled
read continuous        disabled      disabled
transfer block         disabled      disabled
auto read allocation   disabled      disabled
auto write allocation  disabled      disabled
retry count               27           27        1-255
buffer full ratio          4            4        0-255
buffer empty ratio         4            4        0-255
[a bunch of stuff about tracks/sectors per zone skipped for now]
write index enable     disabled      disabled
cache enable           disabled      disabled


What are the best settings to have on these parameters in my application?

Thanks in advance...

Bill
