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 HD322HJ with firmware 1AC01112.
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.

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

BLOCKING ISSUE : your hard disk has 1 offline uncorrectable sectors. Those are sectors that an offline scanning found as unreadable. Offline scanning is a process that can be automatically started by the hard disk logic when a long enough idle period is detected or that can be forced by some tool. Those unreadable sectors are identified and the hard disk logic is waiting for a write command that will overwrite them to try to remap them to spare sectors (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.
