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.
