    i recently got a hard drive enclousure for my old macbook pro hard drive. the hard drive was working fine and i was transferring my files on a my new macbook pro. at some point it didn't want to copy a file so i decided to eject it and then i got an error saying that it was in use, but i couldn't find what program it was so i decided to force eject it. now when i plug it back in it doesn't show up, not even in disk utility.

    i've looked on google but i couldn't find any answers. any help would be greatly appreciated, because i really need to get to my old logic files.

    Open Disk Utility and see if it appears in the list on the left (it will probably be greyed out if it does). If it shows there, click on it and click the "Repair Disk" button. If that doesn't work, post back and tell us what happened and any errors that you get.

    hey,

    it's not showing up in disk utility at all. i also had the same problem with another external hard drive that worked fine with snow leopard but it won't show up in lion, not even in disk utility.

    Try USB 2.0/3.0 if you used FW400, FW800 or eSATA.

    The enclosure may be bad then, or there may have been something that didn't go together just right. I'd see about getting the enclosure replaced if possible.

    Why did you have to force eject it? Take the enclosure apart and make sure the SATA cable is seated properly. If it still doesn't show up when you plug it back in, perhaps the enclosure is bad. Check Disk Utility to see if the enclosure shows up there before you assume it's bad.

    Lastly, I would think you could get another enclosure at fairly low cost and give that a try.

    I have a similar issue.

    I have a 1TB WD Drive in a g-drive slim case. The drive works fine.

    Today I moved the drive to a USB 3 enclosure and my Mac will not recognize the drive. I can eject or format it.

    Instead, I put it back into the original enclosure and it works fine on the Mac.

    I suspect that Mac OS stores some informaton about the interface as I can think of no other explanation.

    I also had this happen move between two USB 2.0 cases and ended up reformatting. I would like to formatting this now.

    Any thoughts?

    Hi,

    Did you find a solution to this?
    I'm experiencing the same problem after a force eject.

    Thanks for any help.

    It appears that the 811 chip in my Plugable hub needed a firmware update.
    That has largely solved the issue.

    i've had the same problem for a few weeks now. I have a 2 TB WD external and
    Have had a similar problem with a 2 TB WD hard drive which also wouldn't show up anywhere. Decided to check the HD cable out (swapped it with that of a friend's 1 TB WD) and it showed again almost immediately

    Just plug the HDD into a pc, delete the hidden files, and then plug it again into your Mac. It'll see it magically
