Slows down and stops

[Guest]

I am using a SuperDisk trying to back up the h.d. on my iMac 500, OS 9.2. In an immediate back-up it starts up O.K., and then gradually slows down. Long before the SuperDisk cartridge is full, the SuperDisk drive stops, although the little gears in Retrospect Express are still turning. When I hit the Stop button, I'm asked if I want to stop the operation. I hit Yes. The program says it is cancelling the operation, but nothing is happening. Now the machine is frozen and I have to restart. Anyone have any idea of how to fix this? Retro Express isn't much good operating this way.

 

 

 

I posted this earlier and did get an answer. When I went back to find it, I could not find either the post or the reply. I do recall the reply said something about the device mounting on the desktop. This does not happen with SuperDisk and iMac. The media (cartridge icon) mounts on the desktop.

 

 

 

Apple System Profiler lists the device as E-USB Bridge.

 

Product ID 1($1)

 

Vendor Shuttle Tech (Shuttle Tech Inc) ($4e6)

 

Driver Version 3.3

 

Driver Name: USB Imation Storage Class

 

Model # (on the drive) SD-USB-M

 

Serial # (on the drive) AA9901234589-M

 

 

 

I hope this helps so I can back up again.
