I know it can read IBM disks. Ok, let me explain...
I work at a hospital where records are kept on this macintosh and backed up on zip disks. For the longest time we have used Mac-formatted discs. However, recently the supplier discontinued Mac-formatted ones and has been giving us IBM-formatted ones. These work, we can save things on them, but there has been a strange problem. Spontaneously, it seems, some files have changed themselves PC formats unreadable to the mac. These disks have never been in any drive but a mac one and have never been written to through anything but one mac program (whose settings have not changed). I don't really know what's going on. I tried File Buddy to rename the files, but the problem is that this eventually happens to every file saved on the zip discs, and we just don't have the time to manually edit the creator and file type information for those files so Mac OS can read them.
I don't know why this started happening, but we had never seen it until we got the IBM-formatted discs, so that's the only lead I have as far as fixing the problem. Is it possible to make them mac-formatted?
