    dnaimagery macrumors newbie

    Jul 20, 2012
    I have a Seagate Freeagent Goflex Desk External Drive 3TB and it was working fine a week ago, but when I go to plug it into my Macbook Pro 15in mid-2010 model I get the following message:

    "The disk you inserted was not readable by this computer."

    with the options to "initialize", "ignore", or "eject".

    I searched the forums & saw a few people had some answers, so I tried using disk utility & terminal to restore the GPT headers, but I got this message in terminal when I tried that.

    sudo gpt recover /dev/disk3s3

    gpt recover: /dev/disk3s3: no primary or secondary GPT headers, can't recover

    Does anyone else have any suggestions on what I can do or what the next step will be? I have important files I need to access & I can't have my external harddrive down like this. Any help would be much appreciated.

    You need to look into data recovery? Software or a service, its up to you.

    One of the first things to do when suspecting a disk corruption is to try it a few times and to try it with a different computer. Not sure if you did that, but it could be worth a try.

    Ive had this happen and jiggering the connection resolved it in one case. Otherwise, I suspect that differences in controllers of moving the drives to new enclosures contribute to this issue.
