I just had the same problem too, after accessing the zip drive, I removed the
same disk (750M) and reinsert it. I get "ERROR: invalid drive". Than I reinsert
the 250M disk, do a directory, remove it, insert the 750M, and I can read it again.
8^O wow!

Awe! Ok! I see what is going on. After doing work with the zip disk (Build/Clean Ros).
I removed it and reinsert it, I get this debug out put,

(cc/view.c:206) CC: Failed to flush cache segment.

A lot of that too!

I can insert the 250M and r/w to it but not the 750M anymore.

One more thing to solve, flush buffers and cache with removable media,
Still Hacken,
