Windows says drive may be going bad but a badblocks test is fine?

I just recently tried to reinstall Windows 7 and it says that it can't install to that drive because the drive may be going bad (but if you click next it will do it anyway). Yet when I run a badblocks test (writes several patterns to the disk and then reads them back) using the SystemRescueCD I get no errors. Should I just ignore it in that case?

It will be worth running the HDD manufacturer's diagnostic/repair utility from a bootable CD/pendrive. If it passes the tests and cleared, that should give you the peace of mind.:)
