From: Mark on 5 May 2008 16:13 I have an SD card that I use to transfer files between my EeePC and my iMac (via a USB SD card reader). I have also used it recently in my Nikon digital camera (after formating it in said camera first with whatever it formats it as). Now, after using it in the camera, I decided to re-format the SD card via the iMac so I could once again use it for file-swapping duties. I booted up Disk Utility and saw/see either "1.9 GB Generic USB SD Reader", or below it "disc1s1" (greyed out). Highlighting "1.9 GB Generic USB SD Reader" I started an MS-DOS erase, but it was taking so long that I force quit DU. I think this might have been a mistake. If I try the same now DU gives the error: "Bad file descriptor". If I highlight "disc1s1" (greyed out) & try the same thing, DU just hangs. If I try & format it on the EeePC via the terminal, it comes up with some error about not being able to, or not finding that particular drive/partition (if memory serves). Is there a way to 'force-format' the card? Or have I shagged (metaphorically speaking) it? Cheers ... Mark

If not, I'd try deleting and then re-creating the partition and then reformatting.

As above, I did format it in the camera while it was being used there - but I was mindful that whatever it formatted it /as/, it wouldn't be Mac/Eee compatible (hence trying to re-format it using a computer) - but would the camera use an MS-DOS (or UNIX) type file system? How (if not erasing via DU), do I delete and re-create the partition?

Cameras all use fat32, I think. >How (if not erasing via DU), do I delete and re-create the partition? fdisk on the Eee? Cheers - Jaimie -- I like my coffee how I like my women... frothing.

It uses FAT16. AFAIK bigger flash RAM cards are pushing towards FAT32 but that hasn't happened everywhere. -- Andrew Stephenson |
