As Biggie said, the purpose is knowledge sharing, the thread is good for a section like this and it will definitely increase knowledge level.
i aint taking a chance refuting that. 😀
My 2 cents on the subject.
Although regular use of the disk defragmenter is necessary in windows box, its not required for a linux box since it uses the ext3 file system... not that it wont help... but isnt that necessary.
on the contrary, for the mac OS, it is not recommended i heard. Im not sure abt this piece of info but i heard so...
A suggestion:
Any defragmenting program is not 100% efficient. It will always leave out a few discrete parts of the hard disk that are not contiguous. But i presume that is enough for most users.
But for perfectionists who want nothing but perfect defragmentation don't use a defragmenting program at all.
A spare hard disk is necessary though.
1) copy all the contents of your fragmented hard disk to your spare.
2) format the fragmented hard disk
3) copy all the data back to the hard disk that was initially fragmented.
This gives 100% defragmentation because on a formatted hard disk the files are arranged contiguously by default.
i sometimes do the above if i have some time to spare. But using a third party program is no less time consuming.
