[comp.sys.atari.st.tech] Problems with Spectre GCR 3.0 reading floppy disks.

kron@netcom.COM (Kenneth Kron) (03/05/91)

I am having trouble accessing store bought disks, disks created by
other macs and even disks formatted by GCR.  I just get disk errors
when I try to copy stuff or sometimes the disk isn't even recognized
as a MAC disk.  These same disks are subsequently readable by other
machines (real MAC's) and copies of the disks sometimes turn out more
readable than the originals.  This makes me suspect alignment problems
but they don't show up in atari mode.  Also I sometimes get errors
when I format a disk in MAC mode and subsequently try to use it but
when I run GCR test on these disks everything passes.

I've tried running the GCR test several times and it passes using
the disks that I previously had errors on.
Anyone else have a simular problem?

BTW- I have no problems accessing files in ATARI mode.

I remember a problem with Spectre GCR needing well shielded drives and
drive cables.  Particularly in the MEGA and 1040 models (those with
internal drives...

Anyone have any details fr the fellow who is having trouble reading mac
disks w his GCR?
