    a friend has a 4TB harddisk that turned into RAW after upgrading to win10.
    the drive is a data drive and not an OS drive.

    i guess, for some reason the drive header got corrupted and that is why win10 shows it as a RAW drive.

    but when he connects the drive to win7 (the system the drives was conneted to earlier) the drive shows correctly.

    i wonder, when the drive header is corrupted then win7 should not be able to show its content either .. except when it stores a backup of the header. right?

    or what could be a reason that the drives shows as RAW in win10 and correctly under win7?

    Some manufacturers used to provide a utility/driver to setup the drive to full capacity for older systems.
    Perhaps this is how the drive has been setup on your m8's win 7 system? Is is a WD drive?

    Try to use acronis or paragon, and their undelete partition function. If the disk isn't messed you have great chances to recover everything, quickly.

    yes i know, but i am more interested in knowing why it shows under win7 and not win10.
    my friend has copied the files already.


    that was my first idea.
    but it´s using GPT and win7 does not need extra drivers for it.

    probably a not so compliant bios and a the two OSes using different routines to behave with such kind of not clear configurations.

    Think to a zip file renamed as .doc Some programs relies just on the three letter extensions and fails to open it, some others goes a bit deeper and manages it correctly.

    There is a good chance that Testdisk will fix the problem.
