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 SAMSUNG HD204UI with firmware 1AQ10001.
The average temperature for this hard disk model is 30°C (min=22°C max=40°C) and yours is 36°C.

Troubled attributes:
Attribute Spin Up Time is failing now! Its current value is 1, the worst value was 1 and the threshold is 25. According to the manufacturer, this is a pre-failure condition.

WARNING : your hard disk Spin Up Time attribute current value (1) is below the normal range (66 - 76) reported for your specific hard disk model. Recently purchased hard disks that were not yet power cycled many times might experience a low value here and it wouldn't be a problem as, after some time, the value should raise towards better ones. If, on the other side, your hard disk is not that new and it was powered on several times this might mean its mechanic is getting old. According to Power Cycle Count attribute, your hard disk was powered on 1676 times and this seems to indicate that your hard disk is not brand new and that some kind of drive's mechanic poorer performance is occurring. Usually this attribute is not so relevant by itself, but it might reinforce some other deduction when looking at the global picture.

NOTE : your hard disk Power Cycle Count attribute current value (99) is below the normal range (100 - 100) reported for your specific hard disk model. Basically your hard disk was power cycled more times than the maximum number the average hard disk was. Power cycles put some stress on the hard disk mechanic. Sometimes power cycles can be caused by a loose hard disk power connector. Make sure it is properly fastened.

The overall fitness for this drive is 0%.
The overall performance for this drive is 90%.
