USB device no longer mountable

Question

Hello all,
My USB camera is having a problem. I must have accidently removed it before it had ejected the last time.
At this point, when I attach it, system.log says:
May 28 21:42:41 localhost diskarbitrationd[90]: unable to repair /dev/disk1s1 (status code 0x00000008).
May 28 21:42:41 localhost diskarbitrationd[90]: disk1s1 msdos 00000000-0000-0000-0000-000000000000 NO NAME
Disk Utility sees it, but when you try to repair it, it says:
** /dev/disk1s1
** Phase 1 - Read FAT
** Phase 2 - Check Cluster Chains
** Phase 3 - Checking Directories
Unable to read directory (Invalid argument)
Error: The underlying task reported failure on exit (-9972)
The funny thing is that my husband's Windows computer can mount it and see the pictures just fine. I know I have the option to load all the pictures on my husband's computer, reformat the memory stick, and copy everything back. But that's a pain. Does anyone know of a way to get MacOS to clean the disk without nuking it?
Thanks,
Eileen

Answer 1

Oddly enough, having my husband copy the pictures on to his PC then caused the camera's SD card to magically be mountable on my iBook again. I"m guessing some minor filesystem change was made by his PC to make it readable again by my mac.
At any rate, it's working, and I have a copy of everything on it.
