It's possible the CHKDSK used is not working the same
as it used to.

Windows 10 (and possibly some earlier OSes) have "robust" NTFS.
This means there is a background scan being done for NTFS. I
suspect it is a background scan of "recently carried out operations",
rather than a thorough evaluation.

Then, if you request CHKDSK from Properties, can that be run
while the robust stuff runs in the background ? Dunno. Since
I've never seen any documentation for the robust NTFS feature,
I can't point you at a reference.

All I can tell you, is that Windows 7 remains the best place
to be doing a CHKDSK. For whatever that is worth. Windows 7
does not "understand" why there are Extended Attributes all
over the place on the NTFS you ask it to fix. But, all the
features are there to mechanically fix it. Even if it is
slow as molasses in springtime. Win7 CHKDSK will eventually
fix your file system.

And always do:

    chkdsk /?

to make sure you aren't missing some of the newer repair flags.
On some occasion, I found a new option, and it actually helped me.
