I don't know if this has been done recently...but oh well I defrag about once every three months lol. I'm interested to see what you guys do.
you're supposed to degfrag once a week on FAT32 partitions, but NTFS doesn't really get that fragmented, you could probably put it off to once every 6 months to be honest.
Ive only defraged aout 2 times and not on this computer theres no need to because every 3-4 i reformat so its a waste of time to defrag
