I have my laptop so that PC can be operated as well. The first time I saved the computer to a Western Digital external hard drive, the computer saved the Mac side to the PC side, first erasing all of the PC materials (as well as its platform). The external drive clearly shows on the computer when plugged in. All I remember is plugging it in; WD began backing up when it reached its set time for backups. Question: Is that something I did, or something Time Machine chose to do?

This is a little confusing.

I'm guessing that you have two computers, one Windows and one Mac.
You also have a WD external hard drive that you use for both of these machines.

I have both Mac and PC on my Mac

No, I had the PC platform put on my Mac; Mac advertises it can do this but they themselves don't install it. Had Microcenter do the work. When it was time to do a major back up, I did go to the genius bar, told them I had both platforms, and to give me any pointers. They said to just plug in the WD and it would automatically do the back up -- of both. (I remember coming back to ask if both would be saved at the same time. The answer was yes. No mention that the external might not recognized both, though now that I think about it, I can't imagine why that didn't come up.)

Now that is a different story,

You have a Mac and are running Windows under Boot Camp. At least I assume it is Boot Camp.
If you are using something like Parallels or VMFusion, let me know.
<div>
Windows, in Boot Camp, is on a separate partition on your internal hard drive.
