Can't change the schedule on Disk Defragmenter.

This is the message I get when I attempt to change it:



I have tried some fix that was suggested in some sites (not about the exact same problem though), but nothing has changed.
Any ideas?

 

That's the exact fix I tried, that I'm mentioning in my post.

 

You didn't state your OS but here is one fix for Vista: Vista Backup error 0x80071A91 and/or failed Windows Updates - Blog

If you are using Win 7 then don't schedule it at all as Win 7 defrags by default in the background when you are not running programs. So no need to schedule.

 

Yep, that's the same fix as the above.

My OS is W7. The reason that I want to disable -as a matter of fact- the scheduler, is that I want to make sure that this (<- the defragmentation) is not the cause for some hdd issues that I'm experiencing. But I can't do that as you can see.

 

OK Sorry to give you the same no-fix link. When I googled your error message I got lots of hits. I just picked the one that looked like it was your problem. Try one of the other links on google.

 

Without the backslash I get an error, and with the backslash, well, I've already tried that.

I wonder if this happens due to Intel Rapid Storage Technology, which I have installed to get rid of some random freezes that occured in the past. Maybe it locks some settings in the hard drive department to make the system more robust. I guess it would be worth trying to uninstall it to see if the problem disappears.

You're right, I had seen first the solution that was about a similar problem (can't be bothered to find the link now) and got stuck in my head for some reason, even though I next saw the other problem that was exactly like mine. No big deal really.
