That message pops up, even though it was formatted with NTFS before. Now Disk Manager states that it has the RAW filesystem, even though it worked just the other week fine as NTFS. Is there a way to repair the file system on the fly, or do I have to recover files? because atm, I don't have enough space to recover all the files on it, so I was wondering if there was an on-the-fly method. I'm not limited to Windows programs and tools, as I have a laptop running Linux Mint, so if any linux centered methods exist I'd like to try them as well... I do have it running through a USB to SATA adapter, so could that be the issue?
