Hard Drive runs at 100%

Sorry I don't have answer. I have similar issue on my HD too. I am hoping what you find out might work for me too.

Lets hope someone helps both of us.

I have a same question? I hope Dell will repair this  problem as possible.   :(

Does it do it all the time? Most likely a windows update installing. I would restart or shut down and you will get the message option to update on shut down. The same thing happened to me and I thought I had malware, but all was fine. Windows 10 doesn't notify you when you are updating until you restart. Good luck.  

Hi,

I am also seeing this problem after upgrading into windows 10. In windows 8.1, didn't see any problem 100% disk usage. But windows 10, seeing 100% disk usage in start up and sometime working time. It occurring repeatedly. I searched in lot of thing regarding this issue but still didn't get any solution. Please help me to resolve this issue.

Use task manager to determine what service is accessing the disk. When you find that, then search to determine how to fix it. If you still need help, then post back here.

Thank you for the response.  How can you tell what service is accessing the disk?  What is considered excessive accessing?  I'm not computer literate...as you can see.

Ever since the windows update (14,02,20) the hard drive on my Optiplex 760 has been running at 100%. It seems to be a permanent defrag loop (defrag at 0%). Looking at task manager nothing is showing up as a hungry disk user yet the read write data is high. Windows support have been a chocolate teapot that has consumed countless hours of my time to no avail. 

Actions taken so far:

Prefetch stopped, windows search stopped, reg edit used to set the driver to 0 instead of 1, Skype disabled, Antivirus temporarily disabled, disk checked for bad sectors, plugins for Chrome etc... disabled, no change, disk still at 100% and PC response now akin to paint drying.

Am considering changing the disk to a SSD but if it continues to loop in this defrag cycle the read write life will be short.

Please, any advice before I go bald!

This issue persists on many Dell laptops, this is a piece of software designed by to cache the active programs or something like that. You can disable the software and it will stop the issue. It's called Superfetch. I have done this fix on atleast 5 of our Dell laptops at work, and it seems to help. 

This is not a bug or hardware error so sending it back to the manufacturer won't solve anything unfortunately.
