Thanks for all replies. Here's the full SMART report:
the 1st-4th data fields are "threshold", "Value","Worst" and "Data",
respectively.

So reallocation is triggered under a narrow set of circumstances, and
I suppose running chkdsk isn't one of them? I guess running a
manufacturer's utility should help. Both of these disks are nearly 4
years old with very heavy use history, so they should be nearing their
EOL. Thanks again!
