My BB hates Macs.

On the Mac, did you try and use the Disk Utility and see if it was detected there? If Disk Utility can see it, you can reformat it and even run a utility to repair the permissions on the disk. You can also try and download another disk repair utility free off the net and see if you can see if it is truly a bad card

The first question I will ask is was it working on your Mac before? If so, do you or have you ejected the card properly from your Mac...? To eject the external media from a Mac you need to drag the drive icon to the trash or use terminal to to dis-mount the media. If this is not followed properly the Mac will corrupt the media card, and not recognize it. Which sounds like your current problem. Windows will still read the card, but Mac will not. Just format the card in Windows to a FAT32, which is ideal for Mac and PC. This should resolve your problems.

Xholmezx78,
what do you mean by format, format it within the blackberrys os, or within the mac's disk utility. once the card is properly formatted, can i eject the disk improperly without having to erase and reformat every time? and one more, say i had an iphone, what sort of disk would it use and what (if any) would be the benefits in terms of compatibility, could i withdraw the card directly without consequence? you seem like the only one of many who has an idea of what you're saying. thanks, -Asa
