CF Card problems

[tuz]

Slightly off-topic since it's not precisely about the Fantom...but I've got a CF card that I just started using a few days ago, I've used it with my Fantom (writing patches from the XV-5080 SVQ files) and it's fine. I'd stick in my multi-card reader and it's fine, and it's super fast. Shows up as a drive in my Mac. Until today when I plug it into the card reader and it doesn't show up on my computer. The card is still fine in the Fantom (THANK GOD) and my xD card I use with my Kurzweil PC3 reads fine in the same reader. But the CF card isn't being read on my computer anymore. Anyone have any ideas to help me?

Does the card show up in Disk Utility?

Yes, and I am able to transfer files via USB to the card while it's still in the Fantom (though this is slower than using my card reader) so I'm dealing that way.

Have you tried "Verify Disk" or "Repair Disk" in Disk Utility?
