I'll try MacWorks this evening and see.
Several questions:
- I think my unit is 512k (one Apple-branded memory
board). Will the disks you refer to work on that?
MacWorks should definitely work - but I'm not sure about LisaTest or
Lisa Office System. I know Lisa Office System really wants 1mb. IMHO,
LisaTest *should* run on 512, but I've never tried it. Have you tried cleaning the head on the disk drive?
Use a cotton swap
with isopropyl alcohol to clean it - I've seen them get pretty gunky.
Also, is the little felt pressure pad at the top present and accounted
for? If it's missing, the disk won't make constant contact with the head
and you'll get random read errors. Also, double check to ensure the
rails the head rides on are clean and free of grease or gunk - they can
prevent the head from moving to further tracks.
I cleaned the head while I had the load mechanism off for cleaning and
lubrication. The drive makes a loud "shushing" sound when turning, so I
suspected the felt pad might be gone. But, it does appear to be there so
I'm not sure what's causing it.
I cleaned and lubed the rails also. The head carriage is moving freely.
Also, what are you using to write the disks? You
really can't use
DiskCopy 6.3 - it writes disks missing some timing information and they
won't work. DiskCopy 4.2, however, works.
I wrote them with DiskCopy 4.2 on a Mac LC II. That's not the problem.
