I heard that doing too many Low Level formats can damage the hard drive. But it make things really fast and remove almost all the malware infections. So, my question is, how many times can we do the low level format safely without damaging the hard drive?

Lets start with defining what a low level and a high/normal level format is:
All this comes down to:
Low Level Formatting, can't dmaage the hard drive. But if the hard drive is damaged already (eg Bad Sectors have been found), and there are not enough hot fix sectors, then it's possible that the drive could appear to have been damaged by the low level format.
There are a certain number of sectors set aside by the manufacturer. During the normal operation of the drive, a sector may "die", so the drive automatically maps in one of the reserved sectors, to replace the damaged one. So the drive will always appear to be "perfect".
If there isn't any more reserved sectors available, then you'll start to see bad sectors appearing.
Low Level formatting is one method to have the drive check all of the sectors, and is the most stressful for the drive. If a bad sector is going to appear, chances are it maybe during a low level format...
Thus, it's possible that a low level format could appear to damage a drive, when it's actually just revealing the existing issue.
