Apple Hard Disk 20 having trouble.

[cjbriare]

I recently acquired an Apple HD 20 for use with my Mac Plus.

But a recent power outage while it was running caused it some damage.

It runs and mounts fine, but when I run the HD 20 test application, it says "Contact your Apple dealer"

I've already tried testing with the destructive option, and formatting it too.

So the questions are:

#1: What can I do to fix this? Maybe what software to use, or procedures

#2: How do i open it? It seems pretty dusty on the inside and i cant seem to open it after removing that screw.

Thanks for your help.
