I hava a 10MB Hyperdrive and the latest software as above. I haven't
experienced this particular problem, but did encounter another one:

      After fiddling around with a number drawers (creating, optimizing,
      using both MFS and HFS, too many things to replicate), I found
      that:

          A) I had a HFS drawer with only 200K of data that the 
             disk optimizer (HyperTools) refused to collapse to
             one 256K disk block.

          B) Two particular files in the drawer were "linked" - changing
             one changed the other, sometimes at least.

      Problem B went away if I disabled the Hyperdrive RAM cache.

      I copied the data to a different drawer and destroyed the original.
      I also disabled the Apple disk cache. I've had no problems since.

I've no idea if this is related to your problems. I would suggest you
try the following, however:

      1) Make your startup drawer a MFS volume. This is what I have.

      2) Disable the Apple disk cache from the control panel. The
         Hyperdrive documentation suggests this in some obscure corner
         of the manual. They say the Apple cache is not write-through,
         which is indeed a bit on the dangerous side for my tastes.

      3) Disable the Hyperdrive RAM cache if things still don't work. 
         This is in the Manager under "Preferences", I think.

Good luck.
