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 HD080HJ/P with firmware ZH100-51.
The average temperature for this hard disk model is 44°C (min=33°C max=56°C) and yours is 32°C.

All the attributes of your hard disk are above the S.M.A.R.T. thresholds set by the manufacturer. This is good.

SERIOUS ISSUE : your hard disk has 16 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.

BLOCKING ISSUE : your hard disk has 32 pending sectors. 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.

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