Although I would be delighted if we could solve this here, I suspect I may need specialized help. I welcome suggestions of sites I can go to get targeted advice for this situation.
Windows 10 Home
4TB hard drive, 678GB free. It’s the D: drive, not the system drive. Data only.
Symptoms:
- File Explorer sometimes takes very long to show the content (green progress bar across the top can take up to two minutes before showing top-level files and folders)
- Some other processes seem to be bogging down (coincidence?), even ones that I would not expect to touch this drive. For example, Excel hangs and Task Manager cannot end the process. I try to End Process and nothing happens. The app is marked as not responding. I cannot see how this could be related but both problems started at about the same time
- Windows runs CHKDSK on the drive automatically when rebooting
Problems seem to point to file system corruption but no signs of physical failure.
Belarc Advisor is hanging at 24%, with 0% CPU and 0 disk. Previously reported on January 24:
