Several months back there were discussions of the annoying noise made by the anti-static brush in the Dataframe disk drives. Does anyone have a detailed description of the procedure to disable the static brush? When I installed the XP ROM in the drive, I looked around a little but I could not actually see the brush. What else has to be removed besides the cover? Any horror stories or warnings about voiding my warranty? I am becoming more and more aware of the noise (it is not really getting worse, but it is very intermittent and so does not blend into the background noise) Thanks for any help Wade Blomgren UCSD Academic Computing Services ...sdcsvax!sdacs!wade

Does anyone >have a detailed description of the procedure to disable the static brush? I successfully performed the surgery on my own DataFrame 20 just the other evening. Here's what I did: 1. Make a full backup, just in case. 2. Remove the three screws from the box. Two on the upper back, and one on the bottom toward the front. Carefully slide the cover off. There are some wires and components packed close to the cover, so *be careful*. 3. Just below the LEDs, two ribbon cables are connected. Disconnect the edge connectors. 4. Lay the innards on a table, with the drive side down. Four screws now appear on the top. They hold the drive in place on the main bracket. Remove them. 5. Carefully lift the rest of the unit off the drive, watching out for several wires that remain connected. This exposes the anti-static brush, which is on the drive's shaft. Using the blade of a flat screwdriver (or similar instrument), carefully bend back the brush, which is essentially a piece of copper with carbon attached to it. Some folks remove it, but bending it back means the procedure *might* be reversible if necessary. 6. Reverse the disassembly procedure, and enjoy the quiet. >Any horror stories or warnings about voiding my warranty? I don't know what this does to the warranty. If you're really concerned, you should check, or even get the repair done under warranty. I did my own because I couldn't afford to be without the disk while the service techs got around to doing the job. > >I am becoming more and more aware of the noise (it is not really getting >worse, but it is very intermittent and so does not blend into the >background noise) I can assure you that the noise gets worse over time. It was driving my entire family crazy, until I did something about it. -- ===================================================================== Ed Anson, Calcomp Display Products Division, Hudson NH 03051 (603) 885-8712, UUCP: [decvax, wanginst, savax]!elrond!anson (Just blame me; my boss isn't even certain about just what I do.)
