    I have an external Freecom USB2 hard drive which works perfectly on both my MBAs running Lion but having all sorts of problems with it in ML on my iMac

    It was partitioned 50:50 HFS:FAT but the FAT partition doesn't want to play in ML. Seams to work ok if I format the whole thing HFS.

    Any ideas?

    Update: Just plugged drive into the back of my Airport Extreme and it's working fine too

    Other than the 4GB limit on FAT there is not issues.
