    When I plug it in it says "mac os x can't repair the disk". It will let me copy files off but I can't add. When I ran disk utility it said one of my files was the wrong size but when I went to delete it, it wouldnt let me. Is there anyway to repair this problem without having to reformat? Thanks

    Also for some files it says "EB" instead of "GB"

    EB is for ExaByte.
    Have you checked Finder > select external HDD >> GET INFO >>> Format and Sharing & Permissions yet?

    It's Mac OS Extended.

    I opened the lock and it still won't let me delete that file. It still says "you can only read"

    Also some files have strange characters in them.

    Seriously, thanks so much for the help right now!

    How big is your external drive? 1 EB = 1,000,000,000,000,000,000 B = 10 to the power 18 bytes = 1 billion gigabytes = 1 million terabytes :eek: :eek: :eek:

    It's 2TB. If that's the case with EB then I have the Mary Poppin's bag of harddrives.

    Does anyone have any ideas?

    Something odd is going on with your drive. Odds are the HFS+ directory structure is hosed up in a way Mac OS X has trouble dealing with. Fortunately, this is fixable without a reformat. Whenever I've had this problem, or similar Mac disk problems, I've turned to Alsoft's DiskWarrior to fix things. Works like a charm - the only downside is that the software costs $99.

    Rebuilding the directory structure with DiskWarrior only fixes problems with the directory structure. It will NOT harm your files.
