What Is Disk Thrashing and How to Prevent It from Occurring [MiniTool Wiki]
What is Disk Thrashing
Disk thrashing (also called virtual memory thrashing) refers to an issue occurring when the hard drive worked excessively by transferring information between the system memory and virtual memory. When your computer has a constant state of paging and page faults and inhibiting most application-level processing, you may suffer from the thrashing.
What does thrashing mean? What results will the thrashing bring you? To explore the answers, please continue to read this post of MiniTool. As the thrashing meaning indicates, it shows that your hard drive is over-worked when you encounter thrashing issue.
Generally speaking, thrashing will happen in the following cases.
- System doesn’t have sufficient memory.
- There is a memory leak issue with your computer.
- The system swap file is not configured correctly.
- Some applications have higher priorities than others.
- There are too many files running simultaneously.
- The system resource is low.
When the main memory is full, extra pages need to be swapped in and out of virtual memory. And the swapping can give rise to a high hard disk access rate. Therefore, thrashing will last for a long time unless the potential issue is resolved.
What’s worse, you sometimes may also receive the virtual memory low error besides disk thrashing. How to fix it? You can get the details from this post: Is Virtual Memory Low? Here Is How to Increase Virtual Memory!

And the remaining system resource is slow that can result in the thrashing. While closing some applications will release some resource so that you can avoid thrashing to some extent.
- Modify the size of swap file: If the system swap file is not configured correctly, the disk thrashing can also happen to you.
