I have come into an old DataFrame 20 that screeches loudly. I seem to remember people claiming that there is an antistatic brush in the unit that is the culprit. Could someone send me info on doing the surgery? many thanks! Steve Crandall att!mhuxt!evans

Steve, Depending upon how old your DataFrame 20 is and which mechanism is in your DF20 (there were two different mechanisms used: Microscience and Seagate), there may be a "cure." If your mechanism is a Microscience manufactured before November '86, the infamous Static Brush problem can be alleviated. Best thing would be to contact a SuperMac Authorized Dealer.

To stop an old HD from screeching, one must place a tiny drop of fine oil under the copper anti-static bushing. This is found by removing the drive unit from the case, removing the Torx screws which hold down the logic board, and lifting the board slightly away from the drive. Caution: it can not come away very far! A small oiler tube can then be slid in under the flat copper pad which rests on the point in the center of the silver fly-wheel. I hope thisinformation is helpful.
