That's a good way to send your hard drive(s) to an early grave.
Not true. With daily defrags the amount of data moved is small and what little wear it may cause is gained back with less "bumpy" reading when using the comp. Last and the only HD I've ever had broken was 20MB one in the early 90's.
If you want to be fanatical, you can defrag maybe 2-3 times a month, but even that's fairly pointless unless you are doing a crapton of file movement to cause fragmentation. Most people really don't need to do it more than 2-3 times per year.
I disagree. Windows itself frags the HD very badly and it writes the files all over the place. All decent defraggers keep files in reasonable places (like commonly used system files and other progs at the start of a partition) reducing both seek times and HD stress.
