Hi-

Forgive me if I have overlooked something obvious. I have been considering a new Mac Pro workflow, so I shot a few minutes of test footage on my 8GB SxS card in Slot A (a blank 32GB SxS card was in slot B - not used for the test), brought the files into my PC (with no issues) and then brought both cards and the camera to a Mac store for testing with Final Cut Pro. (Snow Leopard OS) It imported just fine. But now, I can't access either card from my original PC. The drives show up in Explorer on the PC via USB, but no actual files are listed. I can't access any of the clips either from the Windows OS or from ClipBrowser 2.6. (The drives show up - but the PC doesn't show any files in Explorer) But the files still play from the camera. Because my B slot was empty, I formatted the slot B 32GB SxS card in the camera (thinking the Mac OS messed with it), then copied the clips from A to B using the camera. Then I formatted the A card in the camera as well. No luck. I still can't access the clips or either card with the PC. What did the Mac do to my cards? Is there any way to get them working on my PC again, without access to a Mac? Thanks in advance.

If the PC recognizes that there are cards, can you format them on the PC? This should fix what the Mac did. Then you should be able to format them in the camera.

Whenever you connect a drive to a Mac, WRITE PROTECT IT, otherwise the OS *WILL* write data on it, potentially causing issues as you have seen.

Thanks, Perrone. Lesson learned about the Write Protect. I was unable to format them on the PC side. Whenever I tried, the PC and the camera would hang. Turns out, the USB cable appears to be bad. (Not sure how though, because it just worked fine on the Mac side) Anyway, with another USB cable, the problem has been resolved. Thanks for the quick response!
