Sorry for the delay in making the following report. I finally got around to calling the people in Somerville who, it was reported, have the WD2010 in stock. When I asked about a discount, they guy asked what sort of numbers I was talking about. I said 40-50 (trying to sound optimistic :-), and he said $15.00 (which is the retail price). I asked what sort of quantity we'd need for a discount, and he said their markup wasn't all that great, so he really couldn't offer one. I did ask about the model number, though, after getting a message from Gil, who said the following in a recent message: > One thing -- when you order the WD2010s, make sure that they're the > WD2010B type (I think that's right .. one or both of us should check with > Lenny, who probably does remember). We checked with Lenny, who confirmed that it was the "B" type that are best. Here's what Gil says: > ...These seem to be the more reliable of the bunch -- the reason I say > more reliable is because I've heard of many people using WD2010 (anything) > chips, and some work and some don't. I haven't heard of a WD2010B > failure yet...although that doesn't mean there hasn't been one. Well, anyway, I asked the guy, and he said they have *only* WD2010A's. :-( So, if you're interested, here's the info again: Solid State Sales P.O. Box 74 Somerville, MA 02143 Phone: 1-800-343-5230 Phone: 1-617-547-7053 The total cost, including postage and handling is: $15.00 chip .95 tax (I assume this is for Mass residents only) 1.60 postage & handling $17.55 total He said they'd exchange any chips which turn out to be bad.

Both of them were A's and have been installed in two 3B1's which get a lot of disk activity (full news feeds!). I wonder if it's the WD2010A's or the 3B1's which have the problem. There's been more than one case in the past where certain revisions of motherboards have different timing characteristics than newer ones. -- Mark Dapoz (mdapoz@hybrid.UUCP) ...uunet!mnetor!hybrid!mdapoz I remind you that humans are only a tiny minority in this galaxy. -- Spock, "The Apple," stardate 3715.6.

My experience is that some 7300's (at least mine) DO NOT work with a
WD2010(x) (where x = A || B). I have an early 7300, and a later 3B1.
I bought two WD2010B's from Thad's group purchase, and the 7300 works
fine with the WD1010A in it, but can't find a hard disk when a WD2010B
is installed. I can take that same WD2010B and put it in the 3B1 and
have no problems. This is the case for BOTH of my WD2010B's.
There is evidently some sort of timing or logic problem, and I wish I
knew what it was so I could fix it. I bought a Maxtor XT2190 and
installed the PAL5.1 mods in hopes of using > 1024 cyls and 15 heads.
Since the WD2010B won't work in the machine, I ended up with 15 heads
and only 1024 cylinders.
In summary, I do not think it is true that you can plug replace a
WD1010 with a WD2010 in all Unix-PCs.
