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 ST2000DM001-1CH164 with firmware CC29.
The average temperature for this hard disk model is 33°C (min=24°C max=43°C) and yours is 37°C.

Troubled attributes:
Attribute End To End Error Count is failing now! Its current value is 1, the worst value was 1 and the threshold is 99. According to the manufacturer, this is an advisory condition.

NOTE : your hard disk Power On Hours Count attribute current value (89) is below the normal range (99 - 100) reported for your specific hard disk model. Basically your hard disk was powered on for more than the maximum time the average user did. This means that either all of the reports collected are from hard disks that were not powered on for too long (this is realistic for recent models) or that your hard disk is becoming old. Usually this is not considered as a pre-failure advisory, but you should check whether you want to replace the hardware or keep an eye on its performances over time.

The overall fitness for this drive is 50%.
The overall performance for this drive is 96%.
