Windows 10 PC Always Scanning/Repairing C drive on Startup

JGarcia 6 Reputation points

A few weeks ago, my PC shutdown incorrectly because I had a power outage at my home. Now, every time I start my PC, it runs a scan and repair on the C drive. I noticed in event viewer that there is a 98 error code on every startup - I ran chkdsk like the error message suggests. I ran chkdsk manually on command line and also through Local Disk (C:) Properties -> Tools -> Error Checking -> Check -> Repair Drive. Chkdsk said it found corrupted files and repaired the drive, but the problem persisted. I also tried running an SFC scan and DISM - both said it also fixed my errors but again the problem persisted. Not sure how else to fix this issue.... I am concerned my hard drive is failing and wanted to back it up but I cannot even do that now because of these errors. Any help would be much appreciated.

    I have the same idea with you, your computer’s hard disk may be broken.

    Please press the Win + R buttons to open the Run dialog. Type cmd and click “OK” to open the Windows command prompt.
    and hit Enter. When the WMI interface is ready, type:
    diskdrive get status
    and press Enter again. You will see the status of your hard disk after a short delay.

    Then, we always use HD Tune to measure the drive's performance, scan for errors, check the health status (S.M.A.R.T.), try this tool to see if there is bad sector or other health issue on your disk.
    Note backup your important data in advance, if the disk has something wrong, it will stop work at any time.

    Not a fan of third party tools, to fix something that the system has both induced, and should be able to rectify. So - same problem, or close, a scan runs twice, and then automatic repair kicks in, says it's repairing the disk, and then reboots. Back to starting another scan, if I don't hit the "any key" in the 8 second countdown. This system, I know the HD is good, because I cloned it from a failing HD, onto a new SSD.
    So - the hardware is 100%, but may have inherited file corruption from the old HD. Also - may have inherited Spyware - so first, if you CAN get in, get the system clean with something like Malwarebytes, *(yeah, I know, 3rd party tool, but very reliable) Then, no matter what I did inside the system or out, in safe mode or normal, the scan wouldn't reset the dirty flag. MOVE the physical hard drive to a USB-2-Sata adapter, and hooked to my laptop. Run chkdsk /r and chkdsk /f, still didn't clear the dirty bit (when I use "fsutil dirty query <drive>:")... but once I moved it back to it's home system, boots without scan or error. Multiple reboots later, all is well. No return to extra scans. Hope that helps!
