I had 200-400K on the same drive with an high performance GVP controller for the Amiga 2000. My Quantum was more around 800K or higher. The problem I had with the 296N when I daisychained it to the Quantum was when I did heavy access on the Quantum it would send the heads out of range on the 296N, tried numerious controllers, and determined it was a problem in the 296N, since the 296N did the same thing with an ST-157N-1 later on. Someone suggest it was a Seagate ROM bug, but I never bothered to investigate, I sold it off instead. Older 296's didn't have that problem. >3) If I also upgrade with a new disk, 80-160 Mbyte range- any > opinions, recommendations? I understand that QUANTUM has on > disk cache.

Plus from ClubMac you can get a bare 100 meg Qunatun SCSI drive for under $350. Just gotta lie and tell them you got a "mac cx" or something like that. They think that an SCSI drive can't work in anything but Mac. >5) In planning to goto OS/2 2.0 or Unix in the future, what should > I avoid purchasing?

When you multi-task, your CPU will be busy running the hard drive when it could be running a program. I don't like IDE drives, too many incompatibilitys when you try to daisychain. We had a Maxtor and an Quantum and they both refused to work with each other. After calling around, it was like, well - buy another Quantum or buy another Maxtor. No one offered solutions to getting them to work together, except to eliminate one of the drives. We wound up doing that. > Thanks in advance, > Dan Moyer > dmoyer@oiscola.columbia.ncr.com > 803-739-7681 > > > -- Ronald Kushner Life In Hell BBS +1 (313) 939-6666 P.O.
