Exactly the same thing happened here with a IC35L020AVER07-0; it did not do tagging and i bought it (and many other IBM drives) because of that. I spend some time verifying that it really was the drive that did not do tagging (rests: http://people.freebsd.org/~hm/misc/atacontrol.c) and when i was shure i called IBM technical support. This was one of the best support i ever got: the guy on the other side understood what i meant, he called back without me remebering him to call back, i got feedback, test software, and so on ... It turned out that the drive i bought had DELL firmware in it [ :-)))) ] so they sent me an updated DELL firmware, but that did not enable tagged support. I asked for a cross update program to get IBM firmware; they had none. They wrote one :-), i got it and now my drive does tagged command queueing. And all this for a dirt cheap drive ... hellmuth (Cc trimmed down to -hackers) -- Hellmuth Michaelis Hamburg, Europe hm@kts.org www.kts.org There is a difference between an open mind and a hole in the head.
