Hi, Thanks, the ssd is about four months old, and if I'm remembering right I fed it a query command, that told me that it did in fact support the trim command. For the hds, I've got two of them, plus an external, can I set up defrag so that it goes off say Monday night for one drive and Tuesday night for the other, maybe twice a month or something? Thanks.

Hi,

It's safe to turn it back on; win 7 should defrag the hdd but leave the ssd alone, assuming that the SSD supports the TRIM command which it should / will do if it's under 4 or so years old.

NB: the trim command doesn't disable defragmentation automatically, but win 7 checks each installed drive to see if it supports the trim command and if it does, it assumes it's an ssd and it doesn't defragment it.

Cheers, Ben.

Hello,

I'm running windows 7 on an ssd, that's the primary drive in this machine. I have read on various sites that having the windows defrag service on for an ssd is unnecessary so I disabled it. The problem is I've got two other drives in the box, hdd drives, and I'm wanting to defrag them. THis isn't happening with the service disabled.

Is anyone else dealing with this?

Thanks. Dave.
