Should I be concerned about a warning message to backup?

Episode 1141 (1:29:59)

Tom from Riverside, CA
Hard drive

Tom is getting an error message on his Windows computer that his hard drive may be starting to die. Should be believe it? He just bought it. Leo says to always keep his hard drive backed up, but Leo says that over-relying on Windows can be a mistake. Most hard drives have a technology called SMART which can warn him of some errors. So yes, he should be concerned and always have a backup just in case.
