"Provides important information about your drive"
this interesting little utility can tell you many important bits of information about the hard disk drive.
No real cons
Great utility determining the general health of your hard disk drives. It tells the number of power-on hours and the number of starts the drive has experienced and how many bad blocks have been detected.
