[comp.sys.mac.hardware] problem with hard disks on IIci

ireland@ac.dal.ca (01/11/91)

Hello. I just got a IIci and am having lots of problems using the two
hard disks which I had been using previously on a MacPlus.  The IIci has
no internal hard disk and the two drives are connected just as they were
on the MacPlus. One of the hard disks is a Syquest, the other is a Jasmine
70. I'm running system 6.0.5 with few inits. My Jasmine 70 was formatted
with Silverlining into two partitions. After one of the many crashes, my
startup partition is damaged and cannot be mounted. The second partition
will mount, but I have lots of problems copying files to it and opening
folders and applications. I also have problems copying files to the Syquest
drive. Anybody have any ideas about what the problem is and/or how to
fix it? 
Thanks for your help.   Keith

When he moved the HDs from Plus to CI did he reformat the disks as 1:1
interleave? If not - he's messed up.

The interleave won't cause anything more than the drive to be very slow
(if moved from a Plus to a Ci). And BTW, Jasmine drives are allways
formated at 1:1 interleave, cause Jasmine has tweaked the drivers to
better performance. The problem here is that Jasmine drives had some
other reported problems with the newer Macs, ie. at least Ci an newer,
which derived from some sort of timing problems. Contact Jasmine for
detailed information. They probably have newer drivers allready.
