Thanks. I followed up with a google search & found this page:
There it says
So I am wondering if we examine the stack trace if we could find the code/program that caused the stop? I don't know where to look, but would it be in those log files I originally submitted?
The stack trace will lead to the code in the original DPC routine that caused the error.
The SpinRite scan said all was OK.
Meanwhile, the HDTune has finished, so here are those results:

And here's the Speed map. The reason it slowed down in the middle is that I had to get some work done (couldn't put it off any more) so it was competing with me.
So.... I won't be able to run SeaTools until later. I've still got to get some work done.
Meanwhile, I was puzzled as to why my computer restarted last night while running HDTune. I checked and there were no new minidump files, so I didn't see evidence of a crash. I also did not see a record of restart by Windows Update (looked in History). But then I poked around in the Event Viewer and saw that at about 1:20 AM this happened:
The process C:\WINDOWS\system32\svchost.exe (YOSH-M4800) has initiated the restart of computer YOSH-M4800 on behalf of user NT AUTHORITY\SYSTEM for the following reason: Operating System: Service pack (Planned) Reason Code: 0x80020010 Shutdown Type: restart
Grrr.... Thank you, Bill Gates! I did not know Windows was planning to do a restart!
OK - that's the story so far. Thanks for your help. Will appreciate any new ideas. Meanwhile, tonight I'll try to continue the other disk testing (unless you tell me it's pointless). Before that, though, I'm going to find another way to backup my disk. Remember this whole thing started because it blue-screened in the middle of AOMEI Backupper.
