I can not figure out why my HDD is showing 100% usage in the task manager, I am using windows 8.1

I have disabled BITS from the local services as a recommended fix. This has not worked.

I'm not sure if my HDD is failing, too hot, or its something worse. Any help is very much appreciated

I'm confused. How does your hd show 100% usage in task manager?

Sorry -- you're on W8 and I'm on a W7 system - never even noticed the disk column in Task Manager in W8.

 

EDIT: Please run full scans with your av and with MalwareBytes as a first step.

Allan, may I suggest something? :) Bolts, can you disable the SuperFetch and PreFetch services, then restart your computer and let me know if your Disk Usage still spikes at 100%?

Actually Aura, I'm glad you did post. I misread the first post - it's disk usage and not disk space - I edited my post above to reflect the change.

 

BotlsFan - if it's only after the system initially boots then I agree prefetch is likely causing the disk usage. However, if it continues for a while into the session it could be something else (anything from malware to background defrag or av scans, etc). Does the hd light settle down after a while?

I am fairly confidant I do not have any type of malware. I run eset security suite, malware bytes premium, and super antispyare premium. Also I use this machine for single player gaming mostly. I basically only visit IGN, NFL, my bank, and occasionally check my email.

 

I pulled up task mgr and now it is not spiking and/frozen at 100%

BITS is still disabled... Is this something I want disabled? I think it has to do with auto updating windows

I have disabled both superfetch and prefetch and restarted my PC. Boot time was about the same maybe just a hair longer

Alright, and do you still have 100% DIsk Usage in the Task Manager?

No i do not. It is currently saying 4%.

Just before I disabled the super/prefetch it was not at 100 either. Are these as well as BITS important programs/services?

There are a number of functions that depend on BITS. Set it to manual and it will only start when needed. You might want to check Scheduled Tasks to see what is scheduled to run in the background. Also, check your av to see if it is set to run when the system is idle. If it is, that's very likely what is causing the disk activity.

I would re-enable BITS (by setting it to manual, like Allan said) then restart your computer to see if the Disk Usage spikes up again. On top of that, I could go in C:\windows\Prefetch, delete everything then re-enable the Prefetch service and let the cache rebuild. Do you have a HDD or a SSD?
