Hi,

I rather doubt that that is the problem; it does after all work well with the Quadra 650.

I just tested the Q700 with the zip drive and it seems to work perfectly. I was able to format a disk, install a system on it and boot the machine from it. I am rather relieved that the Q700 doesn't seem to be at fault here.

Any flakiness is this undoubtedly the fault of the drive. Could this simply be a function of the age of the machine? It doesn't work at all with the Mac Plus, it works partially with the Q700, and it works well with the Q650.
