    Microsoft Reserved HDD mounting problem on OSX
    Hey everyone, I would really use some help!! I know this might seem like a common question, but upon hours of search I cannot find a solution.

    A few things beforehand:
    1) I just installed windows 7 via bootcamp
    2) I have a Seagate goflex desk 1TB that I use to store files on OSX and use it as a time machine with no problem. It has two partitions.
    3) I have a 2.1 intel duo core macbook

    So I used my seagate HDD to store some big files that I wanted to transfer to windows 7. When I plugged the HDD in, the device was recognized by windows, but I would not access it in any way. So I went to "administrative tools" -> "disk management" to see what's going on. The HDD was there, but the contents were under one big unpartitioned block. For some reason decided to right click "format to MBR" or "GPT", not sure which one. The HDD still couldn't be accessed. But when I went back to OSX, the HDD couldn't be mounted at all. Plus the name of partition became "disk1s1". When I go back to try "format to _____" (whichever one I didn't do first), it still doesn't work on OSX or windows 7. So now I basically have a 1TB HDD full of photos that can't be accessed through windows 7 or OSX....

    Someone please help!!!
    Thanks a lot!

    Apologize up front, but there's not really a way to be nice about this.

    Why would you click "format" anything on a disk that has current data on it???

    This is a momentary lapse that you cannot afford to make with any drive.

    You likely have a disk with no pictures, backup or any other easily recoverable data on it at this point. You may be able to retrieve the data by using a data recovery software.

    For options, you might want to see this thread.
    I cannot be held responsible for the things that come out of my mouth.
    In the Windows world, most everything folks don't understand is called a virus.

    I will do well to remember my stupidity...

    Anyway, thanks for your input bob. I'll try some data recovery programs then...

    Is the any other way to undo what I did?

    Unfortunately, once you format a drive the MFT and partition table are rewritten to show all space as available for the current file format and OS.

    You may be able to recover your photos and data by using recovery software. First thing to do is not use the hard drive or what data is left on there will be overwritten.

    Take a look at Data Rescue 3. You can download a trial copy to see if it can recover your data. If it can, buy a license. ($99.00)
