I have the same X-Profile and the IDEfile as well. All hard disks are working excellent.
I have found out that a Maxtor Diamond 9 series IDE hard disk (60GB in my case) works best with my X/Profile. All others need hoours to format 2 GB under MacWorks II+.

Please ask me.

No problem, Phil- I'm glad to help!

I have the same card as you do.
You should first do the following: Clean the PCB connectors with a rubber eraser for example- I use Sidol for cleaning the contacts- I don't know if it's available in USA under the same name- it is simply a metal cleaner to clean silver spoons, brass bracelets etc.... it removes any oxidation form the metal surface without doing any harm.

In the next step you should remove all your SIMM's and reseat them again in the sockets.
You can't use standard 32 PIN Macintosh SIMM's, use IBM PC SIMM's instead - the IBM uses a 9th RAM chip for parity, the Mac doesn't. One exeption: special Macintosh IIci for government use needed the same parity SIMM's as the IBM did.
120 ns or higher speeds are ok for the Lisa- even 150 ns should work fine. But I don't think that the SIMM's have a malfunction- it seems to be a contact problem.

I hope this helps you further...
