Recently my new laptop started producing this sparky, "electric" sound that is coming from hdd. It starts, I think, when the laptop warms a bit. Also my laptop becomes slow ( I guess, same reason). I've read about hdd failure and will create backup of my data.
But the weird thing is , if I run hdd intesive operation , like virus scan, the hdd becomes "normal" silent and computer speed returns to normal.
What am I to think of this? Is it possible that kind of continues movement stabilizes it and will intesive virus scans be bad for the drive?
