    Unhappy usb hdd only seen by diskutility and unusable

    I have a early 2012 macbook pro 2.8 Ghz intel core i7
    currently running OSX 10.8.1 Mountain Lion

    I used a 1TB usb hdd (mac encrypted) to use for time machine.
    It gave me trouble so i formatted it a while back and didnt have the time to use
    it with time machine ever since.

    Today i tried but when inserting the usb it only shows up in disk utility, but i can not format or unmount or do anything.

    I've tried some things through terminal but no succes.

    any ideas?

    i tried other ways to get it visualized and true crypt sees the drive like this

    What happens when you use the partition tab and try set it up with a single partition?

    needs partitioning with single apple partition. Could be a partition table issue, but if it's encrypted, that would explain the access issues

    @halo200, i cant do anything at the partition tab.

    @Robert: it is just set up as one disk.. not partitioned in various partitions.
    and it is not encrypted, it was before. and if it was encrypted mac osx is supposed to prompt a passwordfield like it did before i guess.

    maybe use linux to fix this? i just want to reformat the drive now
