No,I dont have any theory for that but have reasons,I have not ask everybody to follow that but in case of people formats very often without having any disk error(bad sectors) in their hard disk, like only to by pass the trial limits of software they should use quick format.Huh? Do you have any data enforcing that theory?
As per microsoft
RRITESH didnt have problem with his hard drive,he was having problem with the software so he wanted to change to Win 7 and install the software so that he could run it.So in his case a quick format is a good choice.When you choose to run a regular format on a volume, files are removed from the volume that you are formatting and the hard disk is scanned for bad sectors. The scan for bad sectors is responsible for the majority of the time that it takes to format a volume.
If you choose the Quick format option, format removes files from the partition, but does not scan the disk for bad sectors.
Another thing hard drives are mechanical device and they do a very intensive process(depends upon the controller) while checking for bad sectors (their heads are operated at much higher rate than normal operation) which cause wear and tear,at read/write time it also cause wear and tear but if you use the process too much(regular format) without much needs, you will have more wear and tear of your hard disk which really decrease the life span of your drive.
Now we people are towards solid state drives.They will not have these kind of problems....
