Windows 10: MR7: Verify = "Permission Denied"

I'd made the System Image 3 weeks ago, and verified it the next day. Today, I ran the verification again. After a half hour, it got about 60% of the way through and then gave me "Verification Failure. Read Error. Permission Denied" The drive had not been removed from File Explorer, so it was still detected. Was this just a transient glitch? Why would it be denied partway through and not from the very beginning? I restarted the verification, this time checking the box to fix errors. At about the same 60%, it said "Read Error - Invalid Argument". I restarted the verification, this time checking the box to fix errors. At about the same 60%, it again said "Verification Failure. Read Error. Permission Denied". The quick scan from File Explorer found no errors. Is this a disk error that chkdsk can fix or something else?

Here's Hard Disk Sentinel on an external drive- which was internal until the number of failed and failing sectors stopped a Macrium image completing:






It can also do surface scans, short and extended tests, monitor temperature...

Crystal Diskinfo reading the same external drive:




Note how much more informative Hard Disk Sentinel is.

@Bob1212, I agree with dalchina. Both your attempts to verify reported "Read Error". This suggests that a sector on on the hard drive that's in use as part of the image has become unreadable.
