Your hard disk is now being compared to real data used to define normal values for your specific hard disk model. This way, the analysis can automatically use proper operating ranges. The images give you an idea of how each attribute is within such range. Current and raw values are shown for easier reference for experienced users. There are 1742 hard disk models in the current archive.

NOTE: not all warnings are reflected on fitness and performance overall values as relevancy is based upon the settings from the hard disk manufacturer who is the best entity deputed to define such relationships.

NOTE : your hard disk has 202 reallocated sectors (this value is very large and your hard disk should be replaced). Hard disks do have spare sectors (usually from 256 up to 1024) used to replace bad ones. This remapping operation is transparent to the end user. Anyway, this can lead to degradated performances (because remapped sectors are in different places of the disk than the original ones and the head needs additional moving). If reallocated sectors grow over time, you might encounter some serious troubles. A backup of the most important data is suggested anyway.
