Windows 8.1 Invisible Hard Disk Usage?
Jul 28, 2014
I have put a 120Gb Intel SSD in my laptop, done a fresh install of Windows 8 from the supplied recovery DVD's. Then upgraded to Windows 8.1 through the Windows store, installed Photoshop 7 and Kingsoft Office and a couple of very small other programs. Everything is working fine. Great. I have hardly any docs music etc on this machine (they are all on my server).
I checked my hard drive usage and discover that I have used 75.3Gb and only have 31.2Gb left. C: partition is 106Gb. I know that the recovery DVD's created restore partitions and they can be seen in disk management. No worries there, they are only a few Gb and make up the total usable disk space (120Gb or so)
So I have been looking for where the bloat is. I have enabled viewing hidden files, and added up all the folders sizes on the root of C: It comes to 44Gb. It doesn't add up to anywhere near the total that I am being told is used 75Gb. So what is using the additional 31Gb or so? and how do I find it?
I have attached a screenshot showing properties of "all in c:/" and properties of "Local Disk C"
As you can see, they are very different.

I am trying to troubleshoot an issue which has been bugging me for quite a while. Basically, I leave my computer on overnight and don't close it to download stuff and updates and also because I don't like the time to boot up.
Well anyways after coming back to my computer at the morning, my computer becomes almost like a brick. The hard drive activity is pretty much always red, everything lags a lot, mouse event, or any input. CPU is not having much of a usage, but RAM is almost full. I attached a screenshot.
I also noticed one of my hard drives, the one which is slower and I only use it for backup and no programs or games, is almost 100% all the time, while the other one which has windows installation and program files is not that intense in activity. Also notice the read and write speed is not that big, but response time is huge.
It only happens if I come back to my computer for a long time not attending it.
I disable system restore, Windows defender real time protection and sleep.

I'm running windows 8 on a partition so I use it mostly for gaming. I have 115 GB on the partition, and when I totaled all the files in my Bootcamp drive it comes to a total of about 80 GB, 50 from games, 20 from the OS. However, I'm constantly getting error messages saying that my disk is almost full and that 105 gigabytes have been used. I've tried CCleaner and disk cleanup but nothing big is found. So why would it be using space greater than what can be seen in the disk when using explorer and is there any way to fix this error (if it is one)?

I encountered a problem a few weeks ago after I refreshed my laptop when it started refreshing the desktop constantly to the point where I couldn't do anything. After the refresh, the desktop was back to normal, though I noticed my disk usage in the task manager was constantly at 100%. I've been troubleshooting this problem by upgrading from Windows 8 to 8.1, I've run chkdsk.exe /f /r, I defragged the disk, ran a virus scan, etc. The only thing that is disabling the service 'superfetch' and/or 'Windows search', though the problem can still arise after doing so. Every now and then the disk usage goes back to it's regular 2-8% but then randomly shoots back up to 70-85-99-100%. It's causing some occasional slowdown.
Here's a screen cap of my resource monitor when it's at 100%:
And here are the specs of my laptop:
-Model: Acer Aspire V5-552
-CPU: AMD Quad-Core A10-5757M @2.5GHz
-RAM: 6GB DDR3 Memory
-HDD: 1000GB
-OS: Windows 8.1

I did a fresh install of windows 8 twice and the problem still persists. I think I have tried every solution offered by google so far and I am at my wits end. It causes freezing in video games and I just want to play all these cool games I bought on steam, not to mention browse the internet without freezing.

Edit: laptop might also chrash while in airplane mode, however making an internet connection is still a surefire way to make it crash.
Seemingly out of nowhere my laptop has been freezing usually minutes after I started it up. I can then restart my laptop and it works for another few minutes and freezes again. While looking at task manager I noticed the disk going up to 100%, however the individual processes did not account for this 100% use.
I tried to increase/decrease my virtual memory but this did not seem to have any effect.
When My computer makes an internet connection for something, a browser or a game, it will skyrocket the disk usage to 100% and freeze. I can start my laptop with all processes and services enabled and when I put it on airport mode nothing will be wrong. however once I enable internet and surf around for about 1 minute my computer will freeze. this happened for multiple browsers and also for multiple games. Also I am currently typing this from my brothers laptop with the same internet connection.

I've been having some major problems with Windows 8.1 (and 8.1 Update) which never occurred to me in Windows 8.
What essentially happens is that the computer completely freezes up and I know that the disk usage goes to 100% as does the active time but the read speed/write speed and average response time are all 0. During this period, i cannot do anything with the machine, not even take a screenshot (And hence to poor quality of the attached picture which shows the scenario).
I've encountered this problem in all of the situations: Upgrade from Windows 8 to 8.1 via StoreUpgrade from Windows 8 to 8.1 via flash driveClean install of Windows 8.1 on to a formatted partition
I've never had this problem with Windows 7 nor with Windows 8 and I've gone through the process of trying to upgrade to Windows 8.1 more than 8 times (literally) on my laptop. I've updated the drivers from the vendor site.
I also encountered this same problem on my desktop once when I performed a clean install on it but I need a stable configuration on my desktop for now for work.
The following are the steps that I've seen online as solutions to this problem and have tried all of them to no avail:
Disable superfetch and windows search servicesDisable Link State Power Management for PCI expressDisable live tilesDisable page files
The configurations for the laptop are as follows:
HP Pavilion dv6-7040tx
3rd generation Intel Core i7 3610QM8 GB of RAM750 GB SATA harddisk (Currently has three partitions plus the small partition created by windows. This problem existed even when I had a single partition. The reason I re-partitioned was ease of formatting and re-installing the OS alone without clearing my data)NVIDIA GEFORCE GT 630M 2GB graphics card.
I do have all the latest drivers from the HP website and the latest updates from windows update. Also, if I check the resource monitor, at these times, the actual disk usage is indeed at very low rates for the different processes. I've attached a snapshot of that as well (had to use a camera then too). Notice the long gap during with the disk active (blue line) is 100% but the speeds (green area) are 0.

I have a laptop running Windows 8 Pro x64, and lately I'm facing an issue where the System process (PID = 4) has spikes of 100% of disk usage according to task manager. I can't watch a video or play a song on a media player properly, for example (there's a crackling noise and the playback is slow), because this process (System) keeps using 99-100% of my hard drive.
Even if I have just booted up and running only the essential OS process and services and completely idle, task manager keeps reporting several spikes of 100% of disk usage. Tried uninstalling antivirus (avast free), but that didn't work. I really have no clue what do to prevent this process from writing/reading so much into HD and reaching 100% of disk usage.
Specs:
OS: Windows 8 Pro x64
CPU: core i3-2350M @ 2.3 GHz
RAM: 4 GB DDR3 @ 1333 MHz
HD: Samsung Spinpoint ST500LM012 HN-M500MBB 5400 RPM

Over the past couple of weeks I have been getting high disk usage on my computer, causing it to run extremely slowly.
Just after I took the attached screenshot, my System went down to around 6MB/s and the "Service Host: Local System (Network Restricted)" jumped to around 16MB/s Looking in resource monitor the main things causing the high read speed are:
'rundll32.exe' and 'ccsvchst.exe' and one just called 'System'

I recently installed Windows 8.1 on my Inspiron 7520 and I noticed that during the startup the disk usage is around 98/99% of my Samsung SSD 840 Pro 120gb.
I saw a lot of posts where the users complain that, during this high usage of the disk, apps don't open, the system freezes around 5 minutes and after that, there are random high usages, even on idle. But in my case this high usage lasts only few seconds (around 30s), I can open some apps with no problems and never happens again on idle, only if I restart Explorer.exe. If I restart it, it happens all again.
My question is : Is it normal? The high usage only on startup? My only worry is mess up with my SSD due this usage.
On Performance Monitor, the process which writes a lot is System. I disabled every 3rd party app on startup.

A week ago I did a completely fresh install of Windows 8 64 bit and everything was working great. When I booted up my laptop on Wednesday I noticed it was running terribly slow. When I opened task manager I saw that disk usage was at 100% despite the combined total of data transfer being 0.8MB/s.
The problem occurs constantly if I set my laptop power mode to balanced but only occurs intermittently at high performance. I've run a chkdsk and everything is showing up fine and bizarrely there is no slowdown whatsoever on safe mode.

My hard disk crashed. I have a recovery cd created on the time of purchase. I bought a new hard disk for this purpose. Now when I am trying to recover from the same cd it is getting stuck at 40 % showing error. I searched for this error and got something as such recovery disk can work on OEM hd. As my old hd has crashed how can I recover over there. Is there any system that dell provide me with necessary operating system so that atleast I can use my system.

My Task Manager:
HP Pavilion with Intel Core i3 running on Windows 8 and NVIDIA GEFORE GT 630M 1GB
My relatively new (about 2 months old) laptop running on Windows 8 suddenly became slow. I noticed it starting yesterday when it became really laggy. Just a few days ago it was working just fine.
I tried to look for solutions online and was worried that it might be caused by malware. I did a quick scan with Malwarebytes and it found no infections.When I boot in safe mode, it seems pretty fine. I tried doing a system restore but I was also informed that it wasn't completely done probably because of an antivirus.
My antivirus is Norton Internet Security and I've read that Norton can be such a hog so I've tried disabling it though not entirely and it hasn't been uninstalled yet. I've also tried running a chkdsk /r because going to Tools > Check for Errors on my C: drive said that there were errors that needed repair.
It has become less laggy but apparently not totally (not to previous state). My task manager however still shows 100% disk usage. Previously Norton would be listed among the top but now it's usually "System" and I don't quite understand why.

A close friend of mine has problems with the hard drive, I reckon. His disk usage it's always close to 80% reaching 100% several times, making impossible to accomplish even the easiest things like listening music or watching SD videos. I've checked the processes and evey thing seems right, cpu usage is very low. I can't figure out what's the problem. The notebook is new, 2 weeks...
I'm attaching a screenshot of a crystal disk report, it's in italian but you should be able to understand it!

I have high usage on my laptop lenovo g580 using windows 8. check task manager and I see cpu memory and disk fluctuating up and down to 3% can go up to 100 at times. When I open google chrome. Watch video or play games. I hear my fan turn on and i think my hard drive and i check task manager and i see the problem happening. I did a virus scan and searched everywhere online. I couldn't seem to find a solution. When I am not using the pc its a stable 3 percent but my memory is at 37 which i barely have anything installed but 1 game and a google chrome.

Randomly my disk usage will rocket up to 100% and sit there locking up my computer and freezing things that i am doing. problems started right out of the box when i got my laptop. CCleaner seemed to lower the amount of times it happens, but it still occurs. I've ran virus/malware scans there is nothing. so its ether windows doing stuff on its own randomly then consuming my whole disk or its having compatibility issues with some program that i have running. this is interfering with gaming and school work. I will include pics of multiple instances of it locking up. I can also include a list of the programs I have on here.

For some reason my disk usage is always at 100%, it never spikes its just a constant 100% and i think its hurting my performance, is there any way to lower this?

After putting my computer to hibernate and powering it back on, my disk usage would stay at 100%. All the transfer speeds are around 0.1 mb/s and I'm not sure what could be causing the 100% disk usage.
Another thing is that it windows notifies me to scan my hard drive for errors, which I have done, but this keeps repeatedly happening.

Attached here are 3 minidumps that have produced just today. A quick view tells me that the error is kernel_data_inpage_error with a bug check code 0x0000007a. After some reading about this problem, I still can't find the cause of this error.
Anyway, I'm having consistent 100% disk usage even there is no I/O processes that is happening. A 0.1MB/s would utilize a significant amount of disk usage. And usually, without any I/O process, the disk usage would only be stuck at 100%.
The initial reading of the S. M. A. R. T test *through HDDScan* showed 567 sectors before doing a chkdsk /f /r (I did another chkdsk with /B option).
I have tried doing another S. M. A. R. T test again before posting this and showed the following result:
This has only been happening recently, I think after updating the BIOS. I haven't tried to downgrade then upgrade though. I checked the condition of my RAM, too, but there's no problem upon performing Memory Diagnostic Tool. I have also disabled Superfetch, nothing happens. I dunno what's really causing this problem though.
This is my laptop's specs:
Manufacturer: Samsung Electronics
CPU: Intel(R) Core(TM) i5-3210M CPU @ 2.50GHz
Motherboard: NP370R4E-S05PH
Memory: 4GB DDR3

I bought new lenovo ideapad Z400 touch 2 month ago with Windows 8. Last week i upgraded to win 8.1 and recover back to win 8 , since then i have some problems.
When I have the Task Manager open, I notice the disk usage climbing to 50, 75, 100 also the CPU , even though there's scarcely any disk activity going on, the laptop's fan is working harder and very noisy , my processor's speed and heat are jumping high without any programs on.
I tried almost anything, checked for viruses, disabled unnecessary startup programs, clean boot, but it still the same.

Today I upgraded from Windows 7 to Windows 8.1. For some reason, after upgrading, my hard disk usage is always hovering at around 60% usage and my CPU usage is always hovering at around 50%. This is when the PC is idle. When I was using 7, the disk would rarely jump over 30% usage and the CPU would never go above 7% when idle. The sound of the hard disk constantly working away is doing my head in, not to mention it's at around 50 degrees as opposed to 45 degrees previously.

I have an issue that has been happening since last week i think. The problem is that even with the computer in idle the disk usage has these spikes. When i want to play a simple .mp4 file it freezes several times and the all computer freezes when the spikes reach 100 %. I don't know what is causing this issue.

I found a lot of 100% disk usage problems and their solutions, but none of them could fix mine.
So here is my issue : every time I copy files from one disk to another or even within the same disk among partitions and install a program/game, my computer becomes extremely slow. A single click is responded after 3-4 seconds. When I open control panel, it shows 100% disk usage. As soon as the file transfer gets over, everything becomes normal.
My problem is not my transfer speed. It is that while a transfer is happening, nothing else works. Even though the transfer rate is 6 -7 mbps

I'm running windows 8.0 and recently for some reason my computer's disk usage is constantly running at 100%. It will dip once every minute or so and load whatever I've clicked or typed and then freeze again.
I've looked extensively online and there is no exclusive cause or reason for this and seems to be a very tricky issue but I will explain what I have done so far:
Disabled Supefetch and Windows Search
Ran chkdsk f command numerous times
Disabled and deleted the page file (that was setting limits)
Tried defragging, disabling firewalls, etc.
Made exceptions for some files that may have been causing issues in automatic scans.
Been told numerous times to open Resource Monitor and check what's doing it and there are numerous things running at different times that this occurs, some are: NTFS Free Space Map, NTFS Master File Table, NTUSER.DAT files, random log files. There is no consistency.
Basic specs:
Windows 8.0 64-bit, 8GB Ram

The new Windows 8 touch laptop I just got is running ridiculously slow. Apps take minutes to open sometimes because the disk is constantly being used by several processes, even when idle.
The main culprits showing in Task Manager are "Service host: Local system", "Windows Modules Installer Worker", and "Antimalware Service Executable". Between them they are using 97+% of the disk and about 50% CPU constantly. It's gotten a bit better since I uninstalled all the trialware garbage that came on it, including McAfee, which was a massive slowdown. I plan on just using Windows Defender for security but it still says it's turned off, could that be the problem?
But for real, I'm pretty sure McAfee slows down the system more than the viruses.

I have an ASUS Vivotab running Windows 8. I am seeing that the service process hits 100% disk usage from roughly 4:58PM - 5:04PM daily. I've made sure that my antivirus is't downloading updates or running during that time, same with Windows Update, Live Update, etc. How can I find what specific process is running during that time that is killing the machine given I know when to watch for it?

I have a HP Pavillion Sleekbook 15-b002ee with Third generation core i5 processor 1.7 GHz, 500 GB Hard disk and 4 GB of RAM installed. Windows 8 came pre installed on it.
I bought this laptop 11 months ago and it worked fine for 10 months and then from the last month its presenting unusual problems. My disk usage is stuck at 100% and the laptop freezes and never lets me work or do anything. Heres what i have already done to solve the issue but have been unsuccessful:
1) I have reset my PC completely and reinstalled windows 8 using the factory setup. Didnt solve the issue, newly installed windows displays the disk usage 100% and the performance is same i.e the system freezes.
2) I have tried adjusting my paging file, no change made a difference to the performance of my laptop. The default system managed Paging file size is something around 3.89 Gb. Does my problem have anything to do with my paging file?
3) disabling the "Windows Search" and "Superfetch" services and still it didnt solve the problem.
4) I have also run checkdisk on my hard drive completely. It took me a complete day to do so but still no change.
5) Before resetting my laptop, an error called "Kernel_data_inpage(http.sys)" used to come on my upgraded windows 8.1. Whats the issue?
So what should i do? Is there any problem with my hardware? Is my hard drive having bad sectors and is that causing the problem?

Lately I have noticed a high disk usage with the computer using task manager. Things that cause this spike is conducting normal operations just as opening an application or the web-browser.
I do not recall seeing any disk usage on task manager for the past few weeks except yesterday (perhaps I did but I do not remember). It appears to me as if those application are using the HDD as RAM even though there is space on the 8GB memory. So I am not entirely sure.
I would like to know if it is normal for applications such as Chrome to be using the disk space? And if so, what may be causing high disk usage?
