Compuitincolo,
Laptops can sometimes be a little quirky in testing. If the long test passes I would then try to do a chkdsk /f on the system. It could be just one bad sector, a chkdsk /f will mark it as bad.
The RTC test failure may be nothing to worry about depending on how it is implemented in the BIOS. What is the make and model of this unit? I'll check and see if this is the case.
