The only way I could think of, would be to hook up her hd to a running computer as a slave drive, or using a external bay for IDE drives. Both ways essentially do the same.
Download ADRC - hd checker. Run the program, but make sure the drop down is pointed to the correct drive letter. This program checks for bad sectors on the hard drive. If any are there, it will report them in real time.
I am not aware of any other way to check if a hd is "good," but bad sectors in a hard drive can be detrimental.
And there is the obvious hd clicking. If you hear any repetitive clicking coming from the hd once powered on, it's a flop.
