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 ST31000524AS with firmware JC4B.
The average temperature for this hard disk model is 33°C (min=24°C max=43°C) and yours is 31°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 1429 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 1485 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.
BLOCKING ISSUE : your hard disk has 1485 offline uncorrectable sectors (this value is very large and your hard disk should be replaced). 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).

NOTE : your hard disk Power On Hours Count attribute current value (93) is below the normal range (98 - 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.
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 97%.
