100% disk usage

[AHarvey]

I am getting a lot of issues with 100% disk usage and I believe it's the cause of a lot of staff complaining their laptops are running very slowly.

I've tried turning things on and off that i've found online but no joy.

I've also read that CMD chkdsk /f /r should be run to check them and it seems this usually sorts the issue.

I've been running this laptop for 4 hours now and it's stuck at 10%, which I've read is very common.

These laptops are win 8 - win 10.

Is there a better, faster way of doing the same thing? Linux live usb maybe?

disk read/writes

Task manager shows disk utilisation at 100%.

no windows 7 issues with any of the laptops, only 8 upwards

that's the problem, you've sometimes got dropbox, antivirus, windows services....it's not just a single process that's causing the issues. You can turn a lot of things off and it still sits there at 100%.

well. i took it home, ran it all night, tried things but to no avail.

This morning ive disabled compatTelRunner and disk usage dropped through the floor.

Restarted and it was back at 100%. compat wasn't running. left it for 5 mins and it was dropping again but it's still getting spikes from system, mcafee and dropbox.

I saw this on a Windows tablet before, try a disk check then after a reboot it fixed it.

The tablet ran very slow whilst it was pegged at 100%

Done overnight, no difference.

Is the Dropbox folder fully synced? If it is, it should only do a periodic check with the server to verify that there are no new files for it to download.

McAfee could depend on what it's doing, any scanning tasks will bump disk i/o, the same if it's updating its virus database.

yep, fully synced but there are 15-20 people using it so it's making changes constantly.

I am wondering if it's something to do with the windows upgrade to win10. it looks like, after some digging about, all the affected laptops have been upgraded vs a fresh install.

I had this problem recently with the GF's W10 laptop. I couldn't figure it out.

Task manager would report 100% disk usage, but none of the processes would be anywhere near 100%. I tried disabling services, windows search, "shop me tips about windows 10" notifications. Loads of things. No luck.

I eventually did a fresh install.

That's the next step.

I've turned off what I can etc and it spikes to 100% for a couple of mins on load up or if you login from locked screen but then settles down.

I've told her to use it as normal, if it carries on, then it's fresh install time. Problem is it's one of the laptops the old IT guy updated to win 10. They've no records of serials etc... :'(
