NOTE: not all warnings are reflected on fitness and performance overall values as relevancy is based upon the settings from the hard disk manufacturer who is the best entity deputed to define such relationships.
NOTE : your hard disk has 12 reallocated sectors. Hard disks do have spare sectors (usually from 256 up to 1024) used to replace bad ones. This remapping operation is transparent to the end user. Anyway, this can lead to degradated 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.
NOTE : your hard disk has 2 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 87%.
The overall performance for this drive is 73%.
Ff in de gaten houden of er sprake is van een toename van re-allocted sectors, maar ik geloof niet dat het nu een heel goed teken is....
