I'm trying to scan for file system errors on my FAT32 USB drive in OS X.

So far I have just tried:

wasabi:~ me$ fsck_msdos /Volumes/MYDRIVE/
** /Volumes/MYDRIVE/ (NO WRITE)
Invalid BS_jmpBoot in boot block: 47494e
wasabi:~ me$

    Use the Disk Utility application in the Applications: Utility folder to check Internal and External drives.

    I'll take your word for it. I ended up using the disk scan on Vista and no errors were detected. For some reason os x had trouble transferring 5GB tar archive. Or maybe it was just Stuffit that Bitit.

    The problem you had with the 5Gb file ... is to be expected.

    FAT32 has an individual file limit of 4Gb .. I suggest you split the 5Gb file into a few smaller pieces to avoid problems.  

    See this wikipedia article ..
    in particular this paragraph

    "The maximum possible size for a file on a FAT32 volume is 4 GiB minus 1 Byte (2321 bytes). For most users, this has become the most nagging limit of FAT32 as of 2007, since video capture and editing applications and some other software can easily exceed this limit."
