Question : Problem: Does anyone know if you can "upgrade" an RDX cartridge with a larger drive?

I have a dead RDX-80 cartridge.  I removed the Seagate momentus drive, and verified its dead.  I tried to throw a different (known good) 160GB 2.5" drive in the cardridge, but the RDX drive will not recognize it.  Does anyone know if this is a do-able thing? The case does not appear to have any kind of circuitry in it that would prevent the use of the drive. The file system of an RDX drive does not appear to be unusual either. Is there a trick to this?

BTW, here is the link to my thread regarding the Dell RD1000 drive - it has a lot of useful information that is directly related to your question, too.  In the end, it couldn't be done.
