As others have stated, no point in defragging ssd, actually it does harm them, as the lifetime of those drives can hold a certain amount of rewrites... So fiddle with the task scheduler in win7 and see if you can turn autodefrag from there, though I'm not sure if it shows up or not as an editable/viewable item.

But apparently there's no point on applying de frag to an ssd as it doesn't have those access time issues of scattered data that a sata disk would do? Anyone comment on this? And does win7 have some sort of background defrag happening? So can this be turned off all together as it would be of no use for my ssd c drive. Apparently defrag a ssd drive can shorten it's life. Probably not by much but hey? Ross.
