Out of the blue, when I plugged in one of my external drives, I could only see a part of the contents in File Explorer; after trying to open the volume again a few times, I rebooted and was greeted by the volume not being recognized anymore (trying to open it would trigger an error saying the volume was corrupted and unreadable). Upon opening disk management, I found to my dismay that the partition was detected as RAW instead of NTFS.
I then attempted a chkdsk /f on the affected volume: the program reported finding a number of issues and reported fixing the volume's Master File Table; this did give me back an accessible NTFS volume, but with most of the contents missing.
I am now running a second chkdsk (/r instead of /f this time). Do I have a chance of getting my data back?
Also, how could this possibly happen? I have always unmounted the volume before unplugging, the disk had been working fine the last time I used it and had been disconnected from power or data cables since then.
