Transferring WAV files to Mac issue

Just recently, with no software change on my end, my MAC began reading my Zip disks improperly. Any time I save multiple samples with similar names, it only recognizes 1 of the files on the Mac. For example, on the 2000xl I’ll save 4 samples (Marvin1, Marvin2, Marvin3, etc) but when I load the Zip disk on mY MAC, it only recognizes “Marvin1” and the other samples don’t even appear. I have been saving samples like this for a long time so I’m confused where the error is occurring. Any help is appreciated.

I also should add that I’ve tried 2 different brands of zip disks as well.

Heard that good sir. I was thinking that may have been the case. I have a CF drive too, just haven’t been up to the daunting task of taking her apart. But alas……
