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. Radford Neal
