    I downloaded and installed the the OS X Mavericks update and now, my macbook won't read my external hard drive anymore. It shows up in the disk utility and I clicked Verify Disk, and Repair, and it seems that nothing is wrong with it. No errors appear in the log. When I click Mount, it tells me that it can't mount it and to use the First Aid options. I've tried Ejecting and Mounting and replugging the device in, but still no luck.

    What can I do?

    What format is the external drive,
    HFS+, FAT, NTFS?

    Did you try plugging it into another port?
    Did you try rebooting the drive?

    It's NTFS.

    I did try plugging it into other ports, same result.

    I'm not sure how to reboot the drive. It's powered by USB.

    In the middle of several books.
    Unless you need the drive to be NTFS, temporarily unload the files and format the drive as Mac journaled. That should fix your problem.

    did you have some extension to write NTFS drives? maybe it's not working with latest OS?
