You must use HDToolBox to make sure "Reselect" is disabled for all drives.

Certain version of the SyQuest ROMS ignore the command to disable reselect.
The ROMS that won't work are those in the 140 series and have the
numbers F3B and F2G.  Apparently earlier ROMS, and later ROMS work fine.

To disable reselection for the quantum, read the configuration
from the drive, disable the reselection, then save this to the drive.
You have to re-boot the system for this to take effect.

Let me know if this does not work (email).

It should be, although the hdtoolbox might tell you that all data on
the partition will be lost.  Be sure to have a backup of all files
on the partition, just in case.  You should always back up your files
when changing low-level data in the rigid-disk-block of a drive.
