The Windows Server version of CHKDSK is RAID-aware and can fully recover data in bad sectors of a disk in a RAID-1 or RAID-5 array if other disks in the set are intact. On Windows NT operating systems, CHKDSK can also check the disk surface for bad sectors and mark them (in MS-DOS 6.x and Windows 9x, this is a task done by Microsoft ScanDisk). I know Linux better than Windows but an by no means any kind of expert.CHKDSK can be run from DOS prompt, Windows Explorer, Windows Command Prompt, Windows PowerShell or Recovery Console. Like I said, the files all seem to be there but I'm looking for some guidance as to how to proceed. Since then I've left the drive alone and unplug it when going into Windows but I'm wondering if there is some kind of recovery program in Linux that will sort out my drive and get things back to normal. Problem is, there are thousands of files on the drive and I obviously can't remember everything that was in there. That lead me to believe that other files (and folders) may also be missing, which I confirmed.

They still worked fine but were also missing from my "music" and "video" folders. The folder contains a bunch of music and video files but they're labelled as "000(random numbers)000.chk" files. I restarted the computer and booted in Linux to make sure and found a new folder called "found.000" and a new file called "bootTel.dat" which were not there before. My bro-in-law knows more about Windows and suggested uninstalling the latest update, which he did, and after restarting, it said it was repairing the drive and I was able to open it up and it looked as though the files were all present, at least in Windows. I started a scan and got about half way through when it said I could only recover the files after paying for the access key so I quit the scan. Now because I'm so unfamiliar with Windows 10, I had to look up online to find a fix and downloaded a trial of a data recovery program so at least I could see that my files are still there. The Windows update on did something to my external HDD where it stripped away the file system and converted it to RAW so the disc could not even be mounted. That way I can listen to music or watch videos in either OS. I run Windows on the SSD, Linux Mint 21 on the internal 2TB HDD (formatted to EXT4 so it can't be read by Windows) and also have an external 3TB HDD formatted to NTFS to be accessed by both Linux and Windows. On my old PC, I was using Windows 7 with updates disabled so I am unfamiliar with Windows 10 and am still figuring it out though so far it sucks and I hate it.

I dual boot Linux Mint with Windows and recently bought a better, used PC that had Windows 10 already installed.
