    I have a SimpleTech - 160G external HD.
    I've used this on a Windows Vista and MacBook before.
    When I try to add or delete a file to the HD, this message is displayed:
    "The item "________" could not be moved because "SignatureMini" cannot be modified."

    Any suggestions?
    I heard that possibly re-formatting the HD using disc utilities could work, but it's worked on my MacBook before.
    As well, doing this could erase everything on the HD, and I do not have enough storage on my computer to store all the files.

    Any suggestions?
    ( If I could backup all files for the External HD, how would this process be done? )​

    Perhaps the permissions have been changed at some point.

    Right click on the HDs icon > Get Info > select "ignore ownership etc." at the bottom of the Get Info window.
