I don't have the 3rd party I also have this problem with my IIcx (Quantum 80 internal). The access light doesn't stay lit once the original read request has been satisfied, but the drive continues to grind away until I deliberately initiate another disk access. It's VERY annoying, and I'd hate to think of it occurring when I've stepped out of the room for a while. I've noticed extreme performance degradation when doing long compiles, or anything that requires an extended period of "normal" disk access... something will trigger the "hyper-accessing", forcing normal accesses to wait for a few spins until the "hyper-access" mode is cancelled... then the fresh "normal" accesses will trigger "hyper" mode again, and so on. Some days the problem has been so bad that I've just shut the IIcx down completely and used another machine. Other days, the problem doesn't show up at all. I haven't really noticed whether the "bad" days were especially humid or not. And it shouldn't matter! Is this a "known problem" yet??? -- ========== ....... ============================================= Ken McLeod :. .: UUCP: ...{spsd,zardoz,felix}!dhw68k!thecloud ========== :::.. ..::: INTERNET: thecloud@dhw68k.cts.com //// =============================================
