Disk Usage at 100%

Q: Disk Usage at 100%

Hello everyone, im new to this website so i apologize if im in the wrong place. My disk usage is at 99% to 100% all the time, and i am unsure how to find out what the problem is and fix it.

Just in case this info helps ill post it.

Processor: Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz 2.40GHz

Installed RAM: 12.0 GB

Windows 10 Home

64-Bit Operating System, x64-based Processor

Preferred Solution: Disk Usage at 100%

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Disk Usage at 100%

This is normal for Windows 7 and newer. You will see this a lot.

What are you using to see this disk usage?

Every 10-40 minutes, the application I'm currently working in [whither it be skype, L4D2, or firefox] becomes unresponsive, and after a minute or two, the window turns white, notifying me that it's not responding. This unresponsiveness quickly spreads to other open processes, rendering them frozen as well. I can still use the mouse, and it appears rainmeter still responds [updates, showing barely any CPU usage].

Steps I've taken to try and resolve this:
Using only one main program, still does it
turning the computer off and on again
Memtest is clean
chkdisk passes
MBAM/MSE scans return nothing
no memory overflows that I can see

While troubleshooting, I noticed that during the 'fit of unresponsiveness' the disk usage light on my tower is solid, but when I looked at the disk usage in the resource monitor, no processes whatsoever were using it [screenshot related]

If any more specifications are needed, I'll be happy to elaborate.

A:Frequent unresponsiveness, 100% hardware disk usage, 0% software usage

It could be indexing. What if you turn off indexing just as an experiment?

Hi guys, hope you can help me please. I'm not too computer savvy so sorry if I'm missing something important or I say something dumb. I'm really frustrated and I'm trying my best to learn and solve this problem.
So I bought this Vaio with Core i5-3210M, 4Gb Ram, Windows 8 64 bit. I had really high hopes for it, coming from an i3. For the first few weeks it worked fine, but then it started to freeze while watching movies. Then it started happening all the time, and the cooling fan became consistently noisy for working at full capacity.
I was used to opening task manager on older systems when this happened to see if there was a non-responding program and force it closed, so I noticed Task Manager offers some more features in Win 8. Here, I see that CPU usage is high, staying always around 70% and from time to time reaching 100. At this moment, the process taking the biggest slice is called VCS System Tray with 58%.
What's perhaps more concerning, is that Disk usage is almost constantly on 100%. And by this I mean it reaches 100 and stays there for long periods of time, perhaps up to 20 minutes, then it falls down a few seconds and up again to 100. During this time the computer is excruciatingly painful to use. To even open a program takes forever. When this happens, it seems that Chrome is at the top of the list of processes with most disk usage, with about 1-2Mbps, but this sometimes changes and the list can be led by System, Utorrent, Octoshape, VCS System Tray, Communication...

Hi, welcome to the forums,
Go to Device manager(right click bottom left corner), uninstall the "VAIO care" driver, get the new driver from Sony support:Sony eSupport - Computers - Support
Install and see whether it helps, check your system for virus infections with Malwarebytes as well.

My laptop (Lenovo Y500 Laptop | Lenovo US) has a 1TB 5400rpm hard drive C: and it also has a 24GB chached SSD D:. The link only shows a 16, but mine was 24. Today, I left my computer idle while I was at class (I'm in college) and when I came back it was frozen on the start up screen Lenovo Logo. As customary with computer problems, I turned it off and turned it on again. It booted up fine, maybe the tiniest bit slow, but nothing really different from the norm. But, when I opened up Chrome, my entire computer froze up after about five seconds, and I had to force shut down. This happened about 10 times (not just with Chrome, but with explorer and Task Manager too). Weird thing is, I only got one BSOD, for MEMORY_MANAGEMENT. When it magically started up without immediately freezing after the first click, I scanned for viruses--nothing changed. I CCleaned the temp files and registry--still nothing. I checked for fragmentation--0% fragmented. Once I finally got Task Manager open, I started thoroughly checking all the tabs. Here's what I found:
Attachment 51822
See how Disk 1 has C: AND D: ? I'm 100% sure that D: used to be on Disk 0. After some more freezing and rebooting, I discovered that Disk 1 maxes out active time to 100% really, really easily. Average response time maxed over 1000. Actually, I'm surprised my computer hasn't frozen since I started typing this post. It's that bad.

Hi all,

I'm having a bit of trouble with Windows 8 on my laptop (I've named my laptop Romulus for future reference in this thread). First off, let me give you a brief history on Romulus' journey thus far:

1.) Bought pre-built from ACER with Windows 8 64-bit installed.
2.) After playing around with it for a bit, I formatted the C drive (deleting all partitions) and installed Windows 7.
3.) Hoping to test out the new Windows 8.1, I reinstalled Windows 8 (a clean install from Microsoft this time... not the original bundled version from ACER). I have yet to install 8.1.

This is where I've noticed a few problems. Specifically, my CPU and Disk usage keep spiking to 100% for no apparent reason. Literally right after booting Romulus, before running any programs/apps, I see these spikes. I boot up, go straight to the desktop, fire up Task Manager, and watch sadly as the performance graphs tease me with those tall lines. The CPU spikes only last for a second or two and usage generally stays pretty low, but I'd still like to know why it's jumping like that. Disk usage spikes to 99-100% more frequently and stays there a bit longer. I've noticed perhaps very slight performance problems and some mouse lag, but I haven't been able to prove a correlation here.

Regarding drivers, these problems arose without any drivers installed (straight Windows 8 installation). Thinking the obvious, I installed all of Romulus' drivers listed on the ACER web page for this model, but the problems persist... Read more

My photos are one drive E. When I use Task Manager to check, it shows a usage of 100% on drive E while I access my photos.

Go to your "tile" screen, and type "Disk Cleanup", then click the icon for this program. Let it run through and it will tell you where you can save disk space. Be sure to click the "Clean Up System Files" button also (requires admin rights), as this will clear out old windows update backups as well.

I have recently purchased an Alienware Alpha, and the first couple of days that I had it, it ran like a dream, however tonight I noticed that everything was going extremely slow and not responding, I was also having trouble uninstalling things. I googled the issue and found out that many of people have had the issue caused by Windows 8.1. I tried to disable Superfetch, as well as Windows Search but there was no change, it was still 100%. I also tried fixing the RAM, is there any other way to fix this? Please help, I make the rookie mistake of not purchasing a warranty and now I am freaking out.

As the title says my pc is bugged with the 100% disk usage issue.

The things I've tried so far are:
1. Disable BITS, Superfetch and Windows search services. Although BITS seems to gets enabled back on its own after a while.
2. Performed a chkdsk /f/r to fix the system errors.
3. Switched windows updates from automatic to manual (not sure if that helps much).

I've read through some other threads but could not find the correct solution. Is there something else that I'm missing which could possibly fix the issue? Any help would be greatly appreciated...

My Win Vista machine seems to add or delete up to 1Gb of data on a daily basis. I have two 50G hard drives and it is the C: drive (the main one for the PC) that is displaying this activity. I basically use the PC to check personal emails and little else, so I am surprised by the disk memory changes each day. Is there a way for me to see what files are changing or being added or deleted from the disk on a daily basis? I tried to see this with Windows Explorer, but it does not show any large files with recent edit dates. So, I am thinking that there must be a better way.

Hi there,

Recently, my laptop keeps spiking to 100% disk usage.
I've tried disabling Superfetch and Windows Search, adjusting the virtual memory, checking if I have the AHCI controller, check disk, none of it worked.
The only thing I haven't tried is System Restore (since I only noticed this after the last update) - I tried it, but it didn't work because it said the drive might be corrupt, and it still didn't work after chkdsk.
Any other ideas?

A:Disk usage at 100/100

Few things you can check:
go to: C:\ProgramData\Microsoft\Search\Data\Applications\Windows and look for the file
Windows.edb and check the size of this file. This is a database file associated with Windows Search feature. If it's too big, sometimes it can grow up to many GB's then it might cause high disk usage when Windows Search trying to rebuild the Search index. You can delete this file but first you need to disable the Windows Search service then re-enable after deletion.Run Task Manager->Startup and disable everything then reboot the PC to see if it fixes the problem then re-enable one by one, reboot until the problem occurs again, then that's the culprit.Run Task Manager->Details, then right click on the Title->Select Columns and put a check on I/O Reads, I/O Writes, I/O read bytes, I/O write bytes then click OK. Click on the Title to sort by I/O Read, I/O Write to find out which process utilizing the Disk I/O most and take appropriate action.

Welcome to Tech Suport Guy
1. I find it hard to connect the install of 8 in December, even if it was the end of December and this problem arising today
However I see there are numerous recommendations before installing 8 on that computer, not least of which is the warning about the Intel Rapid Storage Technology Driver and indeed if you check each download as I have just done a most positive and definite recommendation to update the BIOS before installing 8.

2. The situation outlined above clearly arises from the fact that the computer was originally sold before Windows 8, so therefore it must be prepared for 8.

Hello, so about a month ago I did some updates on windows 10 and after that I've gotten a lot of problems. I started to notice that my computer often would start very slow compared to before. Most of the time I could just restart and everything would be fine. Then I noticed the 100% disk usage problem when I was checking task manager and I started researching about it and I tried doing some fixes that were listed here: https://www.drivereasy.com/knowledg...nager-improve-pc-performance-on-windows-10/#d

I did all the steps there except to disable my antivirus program since it said not to do it if you only use Windows Defender, which I do. I've also done a full virus scan and the offline scan in windows defender. I also thought that it might be my web browser's fault so I stopped using Firefox and I tried Google chrome too but it didn't help. I've searched a lot about this problem now and it really feels like I tried everything that people recommend. The only other thing that I think might fix something is cleaning my pc which I haven't done a single time yet and it's about 1.5 years old so there's a lot of dust but I'm really scared that something might break so that's why I haven't done it yet. Also after I did some of the steps in the guide it fixed the slow starting speed but I still randomly get the 100% disk problem and everything becomes really slow.

Hello all, I have some disk problems it may seem very irrelevant, though I need the windows to be below 8GBs is at 8.6 now and with the removal of features and optimisation it will be there though I have questions about some folders to perhaps drive it down even further.

These are my top usages above 12mb:

Blue: To be optimised, just a cleanup of unneeded files/folders to remain. (ignore)
Red: To be deleted, no need for these.
Orange: To be or all ready symlinked.

Grey: Need more information

Assembly folder - Can I symlink this, is used to store .net assemblies for shared applications... would moving this cause a slow down?
IME - I know I can optimise this by deleting the help files they're imagedisk files are these easy to move or is it best to leave it? And by best I mean will it cause error to symlink.
Microsoft.net - Can this be moved safely is the framework but updating to all the revisions for backward compatibility purposes takes a lot of memory (I have yet to update this copy of windows) so if the whole folder can't be symlinked can only the not often used versions be moved?
INF - is this safe to move, this would be ideal to move for me for streamline purposes will it cause problems?

A:Disk Usage 100%

Nothing wrong with that.
Windows can be doing a lot of scheduled tasks on Power up, Indexing, updates etc. On a new PC a lot of that is going on.

You need to look at other Tabs in the Task Manager - App History, Start-up, Processes. Click the Disk column to sort and identify the worst offenders then go to that software and do some configuring where possible.

Again in the Processes Tab expand the details and you will be able to suss out possibilities.

For example in App history stuff. You can go the Apps and stop live tile updates obviously on the ones you don't use or uninstall them.

That's what you would expect on starting Photoshop. Again probably doing some of it's own indexing, updating, loading modules etc or something like that. Most software can be configured to an extent.

No idea why you are fiddling around with system performance, That's Windows memory management.

For the past week or so my computer has begun acting increasingly odd. When opening programs my disk usage will spike up to 100% and my computer will freeze. sometimes I have to restart to be able to use it again. I've tried several things such as anti-malware and messing with executables that exacerbate disk usage. none of these things has helped

A:100% Disk Usage

Hi @Ecvalor!

One thing you can try in order to fix the 100% Disk Usage is to disable Superfetch (if you're using Windows 8 or 10). In order to do that you can follow the steps in this article:

If this doesn't help with the issue, then I'd suggest to make a backup of your most important data on another location and then run a diagnostic test on the HDD so you can see what its health is currently. You can use the manufacturers tool in case there is such available in the official manufacturers website since it's tuned to the specific firmware of the drive. For instance, if you have a WD drive download Data Lifeguard Diagnostics from here:

Once the results are ready feel free to upload some screenshots so I can take a look.

A:100% Disk Usage


What type of hard drive is it standard or solid state? Does it sit at 100% all the time or during a particular operation? In task manager what is the name of the process that seems to to be utilizing most of the hard disks resources if any?

On a side note could be that your hard disk is reaching end of life do you know how old it is?

A:Disk usage 100%

Hi Thank you. So this suggests lots more stuff is loading in normal mode. I use the Piriform tools, and Ccleaner may very well help, as would Dfraggler. Then I get a more adventurous and use Sysinternals, which has lots of proggies that you dont need, but is small overall and wont be a burden.  AND you can delete it when you have finished with it. Ccleaner can look for duplicates, clear out cache and trash, uninstall stuff and (accept the backup for registry entries) tidy your registry. Sysinternals; Autoruns then Load Order and Pagedfrg are the primaries. If in doubt please ask.

All the time the ram and disk usage is around 90% to 100% and sometime windows even hangs up while using firefox only.I need to use firefox and some light programs only.
I have installed 2GB RAM

A:90% RAM usage and 100% Disk

The RAM use isn't necessarily a problem. All modern operating systems (Windows, Mac OS X, and Linux) will automatically grab as much RAM as they can for caching purposes to improve system performance. In your case, the IGP on your CPU is reserving 512MB of your 2GB for itself, so you effectively only have 1.5GB of RAM. The OS will automatically release memory used for caching if needed by some other program. From the screenshot you posted, you only just booted the system so it's not necessarily out of the ordinary that your computer would have a lot of disk activity, especially on an A4 based system. That should settle down after a time.

However, on such a low end system you should make a point of limiting the number of programs you have running, making sure to use a lighter weight AV program and even go through the Black Viper "guide" to Windows Services and turn off the ones you aren't going to need. You can click on the name of each service to get a brief explanation of what it is and does so you if it's an optional service, you can turn it off if you're not going to use it.

I'm on a Windows 10 OS and the computer is EXTREMELY slow. When I checked task manager, I realized that the disk usage and CPU usage are both almost 100%. I've checked for background apps, tweaked the virtual memory, disabled services, ran troubleshooting, etc. It seems like I've tried everything, but the computer is still very slow. I'm planning on doing an antivirus scan, but I haven't seemed to find anything suspicious yet. Help please and thank you!!!
