[comp.sys.mac] System 4.0/Finder 5.4 Bug?

paulmer@dartvax.UUCP (Paul L. Merchant Jr.) (07/09/87)

I perform disk repairs on Macintosh disks, and I recently
received a number of disks from different people which seem to
have the same problem.  These disks are HFS double sided which
have been used with System 4.0 and Finder 5.4.  Each of the
disks is claimed unreadable by the finder and blocks 42A, 68B
and 74B are uncopyable using Copy II Mac 6.3.  Has anyone else
had this problem, and if so is it related to system 4.0?  I
haven't seen the same problem either on system 3.2 or 4.1.
Also, does anyone know what changes in system 4.1 have caused
the software and hardware compatibility problems we have been
facing?  Thanks.
