Apple better get off their collective butts and answer this problem! We have had this problem on a IIcx with every drive under the sun! Drive begins to "chirp" uncontrollably as though doing some seek-ahead that never succeeds. It is not annoying, it is unacceptable! WrenIV platters, Micropolis, Quantum, Seagate, no difference. AND GET THIS! When we boot the IIcx under A/UX, NO PROBLEM EVER! The MacOS ROMs for the SCSI manager on the IIcx ARE BROKE. I put the same drives on a IIx, no problem, EVER. If you buy a IIcx and a hard drive, you will regret it!

I have had a IIcx with a Quantum Pro-105 installed since about a month after it was released and have had no SCSI problems, and nothing even remotely close the the symptoms described above. I am willing to guess that there is something installed on the IIcx that is not installed on the IIx that you compared it to that is causing your problems. I'm not sure what INIT, or program or whatever you installed on that IIcx to create that problem, but my experience with my own IIcx (and I have a friend with similiar config and a couple more at work with Apple 40's) that the problem is not with the IIcx, but is something else... -- Norm Goodger SysOp - MacInfo BBS @415-795-8862 3Com Corp.

I don't know if this has anything to do with your disk problem, but there's a technical note (#140) which talks about programs, especially inits which do PBHSetVol. Apparently TOPS is one prime offender. The MPW installer is one program in particular is mentioned as expecting better behavior from inits. You might try removing all non-apple inits and see if that helps things. This is only a hunch. -- Nick Nussbaum PO 68 - MIT Branch nn@rice-chex.ai.mit.edu Cambridge, MA 02139
