I dual boot Windows and Pop!_OS and get that pretty much every time I boot into Windows. Drive has no issues though and everything just works fine. I've gotten that message so many times, even on different machines, and never had a problem with a drive. Unless you start to actually notice anything wrong with the drive instead of Windows telling you something is wrong with it, I wouldn't really bother. Although it's obviously a good idea to keep your important files backed up, regardless of the situation. And don't worry about the idle temp, it's perfectly normal.
