whenever i try to transfer a image to a disk with my iic, it writes "bad bits" and then after a second it will timeout to the adt pro menu. Any suggestions?

So, are you getting the 'x''s (errors) as it writes a newly formatted disk after a good transfer?  I had a batch of disks (new old stock unformatted and old Verbatim PC ones) that were all bad - they formatted fine, but attempting to write images to them produced errors (the errors in writing were still there, when I used my ][+ and different disk images and cleaned the drives, so it was the disks).  Going to a different batch of disks (Kodak DS/DD and Memorex this time, instead of my cheap, Chinese, bulk DS/DD and the Verbatims) gave me good disks - everytime.

 

I just did this over the last weekend, breaking out the IIc, after getting my ][+ working.

I'm going from a MacBookPro to the IIc (ROM 0, internal drive) making a set of original disks from .dsk images, using ADTPro.

I start the IIc, using speediboot (to guarantee connectivity and free up the disk drive).


The macs are winning...

Can it be that the disks are simply too old now? The plastc may very well have warped.
