I guess you can't recognize one either. :-) What he has is not a Torx screw. -- Regards, Doug Miller (alphageek at milmac dot com) It's time to throw all their damned tea in the harbor again.

I'm not sure now if it was Radio Shack or Sears-- but I bought a <$20 set that has about a dozen tips for jeweler's sized unusual screw heads. There are a couple Torx Plus tips in there & I've taken apart a bunch of hard drives with them. [I've been taking them apart to play with the magnets--- not as strong as I expected in the newer drives] Curiosity got the best of me-- this isn't my set, but Sears has this 18pc set for $20; Sears item #00941709000 Mfr. model #63518 [no torx plus but a T6, T7, T8, & T9 size Torx] Ah -- Here it is- Radio Shack, $15 Model: 64-2973 Catalog #: 64-2973 Kronus 20-Piece Electronics Bit-Driver Set 1 x Ergonomic Anti-Static Handle 4 x Slotted Bits (2, 2.5, 3, and 4mm) 2 x Phillips Bits (#00, and #0) 5 x Torx Bits (T-6, T-7, T-8, T-9, and T-10) 3 x Hex Bits (1.5, 2, and 2.5mm) 2 x POZI Bits (#00, and #0) 3 x Hex Round Ball Bits (1.5, 2, 2,5mm) 1 x Plastic Carrying Case Especially for such an inexpensive set is is pretty well built except for the cheap plastic case.

From: David C. Partridge on 16 Jan 2006 08:48 Cough! I said class 1 not class 100! Sure a drive will function for a while with the case off, but it will die soonish (maybe a few days or weeks, but it will die). If OTOH all you are doing is extracting the magnets from old drives - then go right on ..

A >"clean" "average" room will contain far less than the 600 particles. Well, having managed a real clean room , you are way off base. First of all, the particle count is per cubic foot. Clean rooms are classified by the sustained particle count averaged around the entire room. The average count in a typical home/office/light industrial room is about 500,000 particles per cubic foot, and the particlas are quite large (several microns or tens of microns). The first level of clean room we define is a class 100,000. This isn't a real hard level to achieve and can sometimes be done without real expensive HEPA filters if the working conditions are clean enough. The Space Shuttle high bay room is maintained at class 100,000 (my experience is with NASA). The next level is a class 10,000, which certainly requires a high level of filtering and monitering with special clothing for the occupants. Next comes a class 1000 which is getting serious. You are into laminar flow air systems and special training for the people. Computer chips are assembled in class 100 or even class 10 (!) rooms, since a single particle can ruin a product. At this level, even the way you move can disturb the room's particle count. Everyone is trained to move slowly and be aware of where the downwash from the airflow over your body goes. By this level, the particle size is usually measured at a much smaller, sub-micron level also. A single small tear in a HEPA filter can take the room out of spec for quite some time, requiring a long, slow damp swabbing of all surfaces. Dennis

A > "clean" "average" room will contain far less than the 600 particles. > you could contruct a clean box to stifle the clean room naybobs somewhere, (i am looking for link in my encyclopedic favorites), on web there was a design plan for clean room box involving a sturdy cardboard box , spray contact cement, largish HEPA filter, shop vac, heavy ~ 5mil clear plastic, duct tape then some spray either anti-static or water mist ? can't remeber well most could probably figure out how this stuff was used the only trick was purging of contaminates when it was exposed when opening the box > > > For what it's worth, I've had a drive running non-stop for over a week > without its cover (platters exposed) and haven't had any hiccups.
