So long as you keep your data backed up, you can play it by ear.

"Backed up" means a copy is stored on some data medium that is:
A) Not permanently connected to the computer (USB drive, DVD-R, whatever) AND
B) Accessible by some other computer.

You’re right, of course. The other warnings didn’t pop up until AFTER I’d backed up to E:.

So, I have several options at this point. I’ll move forward with replacing the D: drive and copy from E: to the new D:, then see what happens.

If the problems persist, then I can decide which way to go.
