Hard disk health and reliability analysis

Almost every EIDE or SATA hard disk includes S.M.A.R.T. data. That information is collected by the drive itself and contains data that the manufacturer considered relevant to check reliability. The data is made up of several attributes that have a current value, a worst one, a threshold, some raw data, and some flags. Basically, when any attribute's current value is below its threshold, the hard disk is considered unreliable and likely to fail. By using several techniques, this report tries to give a wider range of information, basing its analysis on advanced comparisons with normal values based on real hard disks and on expert-like checks. The final results are not to be taken as an absolute truth, but they are almost as good as a professional expert advice about your hard disk status.

Your hard disk is a SATA WDC WD2502ABYS-01B7A0 with firmware 02.03B02.
NOTE: a S.M.A.R.T. model for this hard disk is not available (yet). Attribute comparison has been made against standard values. New models are computed often and in the future this hard disk should take advantage of the additional crowd knowledge.

Your hard disk temperature is 29°C.

Troubled attributes:
Attribute Reallocated Sector Count is failing now! Its current value is 29, the worst value was 29 and the threshold is 140. According to the manufacturer, this is a pre-failure condition.

SERIOUS ISSUE : your hard disk has 1365 reallocated sectors. Hard disks do have spare sectors (usually from 256 up to 2560) used to replace bad ones. This remapping operation is transparent to the end user. Anyway, this can lead to degraded 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.

The overall fitness for this drive is 0%.
The overall performance for this drive is 100%.
