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 HD153WI with firmware 1AN10002.
The average temperature for this hard disk model is 32°C (min=23°C max=41°C) and yours is 32°C.

Troubled attributes:
Attribute Raw Read Error Rate is failing now! Its current value is 1, the worst value was 1 and the threshold is 51. According to the manufacturer, this is a pre-failure condition.

WARNING : your hard disk Spin Up Time attribute current value (37) is below the normal range (58 - 73) 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 103 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.

BLOCKING ISSUE : your hard disk has 3209 pending sectors (this value is very large and your hard disk should be replaced). Those are sectors that couldn't be properly read and that the hard disk logic is waiting for a write operation to try to remap to a spare sector (if available). According to the Reallocated Sector Count attribute, your hard disk seems to have available spare sectors. A simple disk surface scan won't be enough to force the remap operation. You need a read/write surface scan to remap the sector. The best option should be a tool that knows about what should be read from that sector so that it has some option to apply the best fix to the missing data.
