100% disk usage becomes a headache for users if it isn’t fixed in time. Even though Windows has improved a lot, bugs still exist, and one such bug involves IaStorA.sys 100% disk usage when doing nothing. What is peculiar is that even with minimal activity on the PC, the file keeps using the disk at 100%. 100% disk usage issues force the PC to lag down and show unresponsiveness when idle for a longer time. While the PC can return to normal usage after a restart, it can also happen on its own, but it’s still annoying.
What is IaStorA.sys?
IaStorA.sys is a driver file associated with Intel Rapid Storage Technology. It is a Windows driver designed to offer accessible communication between your PC and hardware or other connected devices. The iastora.sys process is a safe driver file and doesn’t pose a threat to your device. In addition, the driver has direct access to different internal features of the operating system or hardware. You can quickly stop the driver from Services in Control Panel.

1] Check for Hardware Failure
Poor hardware is the main reason behind the different issues with your computer. Bad hardware can cause pop-up error messages when reading, copying, moving, and deleting data, and it can also slow the computer’s performance. If you suspect a hardware issue, contact the technical support team.
Most OEM tech support will run a hard disk diagnostic, which may take more than an hour. These tests will clarify if your hard disk health has deteriorated and is about to fail. If your laptop or storage device is under warranty, you can get a quick replacement instead of a new one.
If you do not want to go for a long press, you can download the OEM software and check it yourself. At the same time, these consumer software programs aren’t as advanced as OEM support, but they can help you assess the risk of failure.
Check this if you need some Freeware to Monitor Hard Disk for Potential Failure.
2] Run CHKDSK in Advanced Recovery
CHKDSK is a disk checking utility that can check file system and file system metadata of a volume for logical and physical errors. As you know, the disk has issues. It’s best to run the utility in Advanced Recovery. You will need to use a bootable device.
You can go to System > Recovery > Advanced Startup and click on the Restart button.
Once in Advanced Recovery, Go to Troubleshoot > Advanced Options > Command Prompt.
Type CHKDSK here, and press the Enter key. Type Chkdsk /f /r and press the Enter key. Let the scan complete and fix the problem with the disk.
