This information primarily applies to TEAC drives, but other brands
have been known to have this problem as well.
Multisoft, the maker of PC Kwik, instructs its users of "Superon" or
"Poweron" disk caching programs to alter the batch files that are used
to load the disk cache. They are generally loaded in the AUTOEXEC.BAT
file as "Call Superon" or "Call Poweron". In the appropriate batch
file, you need to add a switch to the end of the "Superpck" command.
PC Kwik instructs the user to try a variety of switches starting with
the switch "/D#". If this fails to allow formatting of the double
density disk, change the flag to "/D-" and try again. If this fails,
use "/-x *" where "x" is the drive letter. DO NOT USE A COLON after
the drive letter. These switches express progressively longer delays
in the timing function, which is where the problem lies.
The following are examples:
Note: Use only ONE of these lines.
Superpck /-a * (For the drive B, substitute "b" for "a".)
