    Exclamation Deleted & overwrote partitions, files still intact and readable on deleted partition

    I used to have several partitions with media files on them, but when I reinstalled ubuntu I had to overwrite them. Windows was hibernated during the process (grub was broken and I couldn't get in to shut it off). I've already logged in and out of ubuntu several times and the only partitions it sees are the Windows partition and itself, but when I logged back into Windows it still sees the 2 overwritten partitions (it could never see the ubuntu partition because its an ext3 or 4) and all the files on it are still intact and readable (even itunes can play them). The only way I can explain this is that Windows created a copy of the partitions and files and is now redirecting the OS there. How can this happen? And if that is what happened where would it be stored? This is freaking me out... did my hard drive grow an imagination? o_O

    thanks

    Not sure about how that is possible.

    From Ubuntu, can you please post the output of

    Code:
    sudo fdisk -l

    I recommend you follow the instructions in the link at the bottom of my post.

    Post the results back here so we can have a better overview of your current setup.

    Thanks.

    Re: Deleted & overwrote partitions, Windows still can read/write files on the partiti

    A guess & why you should not hibernate if dual booting.

    Windows has the old partition table and file index in memory. The Ubuntu install did not overwrite much data as it is not very large. So windows is overlapping the hard drive sectors with Ubuntu.

    If you write anything into the media partitions, you will corrupt Ubuntu. You may actually be able to read much of the data but you are working like testdisk or photorec do in trying to recover data from absolute sectors.
