But what if you could know beforehand if your hard disk is going to crash in near future? What if you could tell that your hard disk has started to show the signs of aging or malfunctioning. Sometimes, read operations resulting in such errors can take a long time due to many retries.Once your hard disk has crashed, there is not much that can possibly do – your data on the hard disk is lost and it is unusable. If you do absolutely nothing about this, only consequences is that you'll get errors when you try to read those sectors. In either case, you can continue using the drive. Maybe the drive was writing to those sectors when power was cut, causing them to be corrupt, even though the drive is physically totally okay. If that value doesn't go up, I don't know what's going on. If it goes up, that means the drive developed new bad sectors, which increases probability that the drive will fail. So you should probably first use something like nfi.exe to find what file is located there, so you know what got corrupted.Īfterwards, reallocated sectors count raw value may or may not go up. Though note that after you do this, whatever data is located there will be corrupted, but you won't get an error anymore when reading it.
