100% disk usage is a widespread problem among Windows users that has several possible origins. Having your disk 100% loaded is not healthy and leads to problems with the PC usage. Let’s figure out which problem causes 100 disk usage Windows 10 and troubleshoot it in a step-by-step manner.
Why is my disk at 100?
High disk load is a problem that has a lot of possible sources. Disk 100% load means that it works at its peak read/write speed. Alternatively, it just doesn’t work properly – so the computer fails to read or write the required data. Normally, the operating system will never use so much of your disk, unless the problems happen. However, we will check out the possible software and hardware problems in the next chapter. The most common visible effect of having your disk drive overloaded is a very long response time of any operation on your computer. All launched apps will likely freeze at the moment of peak disk usage. Aside from the PC slowness, you may also spectate the inability to open any folder in your file system. In other words, your PC becomes useless, and it requires an urgent fix.
Fixing the disk 100% load
As I mentioned before, there are several different reasons for the disk overload. During the troubleshooting, it is important to define it correctly and completely – otherwise, the effect will only be partial or there will be no effect at all. By the depth level, issues can be divided into software, firmware and hardware.
Software issues that cause disk 100%
Software issues stand for the situations when Windows 10 disk 100% usage appears during the normal usage of certain applications. That possibly can be the intended behaviour of the application. For example, disk check-up tools as well as anti-malware software are forced to take the max disk read/write speed to provide the max performance. But much more often, programs will put your disk at 100 because of optimisation issues or bugs. You can easily uncover this source of the problem by opening the Task Manager. The sole app that takes the vast majority of disk capacity is what exactly causes the overload.
Troubleshooting the software issues
For that case, reporting the issue to the developer will probably help – they may consult you on how to decrease the disk load. If the problem appears because of the program malfunctioning, the developer will probably issue a bugfix soon after. However, if you find out that the problem is only yours, and no one can repeat it, you should go to the next step.
Summary for software troubleshooting
- Detect the application that takes too much disk capacity
- Try using it in a different mode
- Contact the developer to get help with troubleshooting
- If the problem is not related to the program – go to firmware issues troubleshooting
Firmware, or more precisely, the drivers for your storage devices, are very important for the correct device work. Drivers act like an instruction for the OS on how to interact with the device. And as you can guess, wrong or outdated instructions can lead to issues like disk 100% load. In some situations, the problem can be in several places simultaneously. Disk drivers can conflict with drivers of another device you use, causing serious problems with their coexistence. The last situation happens pretty frequently when you use exotic equipment or very old devices.
To solve firmware issues, you first of all need to install the most recent version of drivers for the disk. It is strongly recommended to get them from the manufacturer’s website. Primarily, you need to find the specifications for your disk, at least its family name. After that, just search for the drivers for your device on the manufacturer’s website. Remember that you should get it exclusively from the manufacturer – otherwise there is a big risk of repetitive malfunctions and malware.
Some vendors also offer the monitoring tools for their product lines. That makes the life much easier, as these utilities also show the disk diagnostics information and will help you with uncovering the possible hardware issues.
Fixing the driver conflicts
The aforementioned situation when the disk overload happens because of the driver conflict requires more steps to fix. Aside from the driver issues of the exact disk, you need to troubleshoot the devices that are interacting with the disk as well. In particular, those devices could be RAM extension units (like Optane modules) or RAID arrays.
RAM extension units sometimes work wrong on the motherboards that are not 100% compatible with such modules. For sure, the manufacturer should likely have a licence for using such technologies, but there are still a lot of copies based on reverse-engineering present on flea markets. Using surrogates of this kind with original equipment can create problems with both hardware compatibility and driver conflicts. To understand if it causes such an issue, plug out the extension module, and try to boot your PC once again. Remember that this device must be detached only after the complete shutdown of the computer.
Fixing the conflicts between extension modules may involve updating both drivers for this module, motherboard firmware and storage device drivers. Searching the corresponding drivers and firmware on the manufacturers’ websites and installing them will likely solve the problem. However, if you use the no-name motherboard from Aliexpress that supports this technology, the problem may hide in the hardware incompatibility of this module. Therefore, only cease extension module usage or changing the motherboard on the one that has an official support.
RAID arrays belong to the other kind of problem sources. Complicated hardware conjunction is relatively hard to set up, and the problems like 100% disk usage Windows 10 is an often case when something went wrong. In that situation, follow the RAID setup guidelines until you get the system working without any problems.
Step-by-step summary for firmware problems solving
- Update the disk drivers
- Update the motherboard firmware
- Update the drivers of memory units (RAM extenders/ROM)
- Disable the units that may possibly cause conflicts & high disk load
- Go to hardware issues troubleshooting
Hardware issues that cause 100% disk
The most unpleasant reason for Windows 100% disk usage is when something goes wrong with hardware. There are many more places where something can get wrong, and fixing it is rarely possible. Fortunately, hardware problems are a pretty rare reason for the disk 100% usage. If you tried all other troubleshooting methods and they did not give any effects, the problem is likely hidden in hardware. The possible hardware sources for 100% disk usage are problems with the connection interface, connection adapters (IDE to SATA, Flash to IDE etc) and the exact disk.
Troubleshooting the connection interfaces & adapters
The connection interfaces and adapters issues are easiest to resolve. SATA cables are pretty cheap and widespread, so first it is recommended to purchase a new pair of ones. One cable is for power supply, the other – for data transfer. It is better to substitute both, in order to eliminate any possible issues. The additional sign of problems with the connection interface is sporadic disconnections of the disk – it may randomly appear and disappear from the list of storage devices.
It is slightly harder to solve the hardware issues with disks that use PCIe and M.2 connection interfaces. In the case of PCI Express, you can try to plug the disk into a different port on the motherboard – but there could be no free PCIe ports. M.2 slot is oftentimes represented as a single available slot of this connection interface on the motherboard. In the latter case, the only way to figure out the problem is to plug it on the other computer with this slot on the motherboard.
If changing the connectors or trying a different slot does not give you a proper effect, and you still see your disk running at 100%, the problem is likely inside of the disk.
Troubleshooting the disk issues
Generally, the disk issues are not always related to the malfunctioning. Some of the old HDD variants may have such a low read/write speed so the modern programs will easily overload it. But the probability that you use such an old disk is pretty low. A much more common case is when something goes wrong with the exact drive, or with its controller. You can only diagnose that the problem is with your disk – fixing it requires special equipment, or maybe even impossible at all.
For HDDs, a reliable sign of a disk malfunction is any kind of scratchy or tinkling noise. Hard disk drives have their own noise – exactly, the sound of a spindle rolling at around 7000 RPM – but it sounds rather like a rustle. Mechanical noise means that moving parts inside of the disk – read/write heads and platters – collide with each other, thus damaging the platters that contain the data.
SSD of any kind is harder to troubleshoot since there are no visual signs to recognise the malfunctioning drive. The only way to ensure that there is a problem in the exact disk is to plug it into the other computer. If it will keep showing you a high disk load – the problem is likely there. You can bring it to the service centre, and if the problem is inside the disk controller, you may be saved. But fixing the exact storage cells is very difficult and just irrational. To ensure that the disk is the source of a problem, you can scan it with disk scanning programs. I can recommend you a free program that have a two-decades long reputation – Victoria. It will easily uncover the disk wearing, that is impossible to see with your eyes.
Hardware issues fixing instruction
- Check-up the connection interfaces
- Try to plug the disk into the other PC
- Check the disk for the mechanical damage
- Check the disk for wearing with disk scanning tools
- Bring the disk to a service and purchase a new one
