    Unhappy My external HDD is not mounting!

    I have a 250 GB Seagate FreeAgent external USB HDD. When I connect it to my Linux computer it opens up fine. I can add/remove files.

    Disk Utility does show the presence of the HDD, however I cannot mount it, I cannot even run a First Aid on it, I can't even "Eject" it....

    Disk utility gives the following information:
    Name : Seagate FreeAgentDesktop Media
    Type : Disk

    Partition Map Scheme : Master Boot Record
    Disk Identifier : disk6
    Media Name : Seagate FreeAgentDesktop Media
    Media Type : Generic
    Connection Bus : USB
    USB Serial Number : 6RY05S3H
    Device Tree : /PCI0/EHC1@1D,7/@5:0
    Writable : Yes
    Ejectable : Yes
    Mac OS 9 Drivers Installed : No
    Location : External
    Total Capacity : 232.9 GB (250,059,350,016 Bytes)
    S.M.A.R.T. Status : Not Supported
    Disk Number : 6
    Partition Number : 0

    Any idea how to proceed?

    Had a similar deal when my partner turned off computer mid SuperDuper back up. To get it to mount i removed the cover off the HD and unplugged the multi pin cable but left internal power connector seated. Then power up unit until you hear it stabilise RPM and make a quiet click then shut down, replace multi pin plug and reassemble. Showed up and mounted after that.
