Do you often see some of the files in your Windows computer recopy themselves several times? Would you like to end that? In this article, you’ll learn what iaStor.Sys is all about. Also, see how it functions and how to solve it.

What is iaStor.sys?

An iaStor.sys ( Intel SATA Storage) is a Windows driver for RAID ( Redundant Array of Inexpensive Disks) devices.

RAID is a form of hardware arrangement where similar data copies itself into numerous hard drives to back up data in files. 

An iaStor.sys has access to the hardware, software, and drivers of a RAID device. Thus it runs and manages RAID devices.

It runs in Windows XP, Windows VISTA, Windows 7,8, and 10.

The default location of iaStor.sys is the C:\Windows\System32\drivers folder

How iaStor.sys Functions

IaStor.sys is essential for your RAID device to run efficiently. It controls and manages your device in a bid to maintain file integrity.

It is installed into your device during configuration.

A user can run at least two hard drives simultaneously using iaStor.sys in a RAID configuration.

It runs silently in the background and without notice on the Windows Task Manager on your computer.

The only time you will see notifications about iaStor.sys is when there’s a problem.

Error problems linked to iaStor.sys usually arise when:

  • There’s information loss during the configuration process of the program.
  • The RAID device has faulty hardware.

These errors are detrimental to both the hardware and the whole system because iaStor.sys is a driver.

It will lead to hardware malfunction first and then cause system malfunction eventually if it’s not dealt with on time.

An early sign of system malfunction indicating problems with iaStor drivers is BSOD ( Blue Screen of Death).

An error reporting approach that the Windows Operating System uses to protect itself from damage.

When iaStor.sys displays a BSOD, you should reinstall it to update the RAID hardware. Otherwise, if you fail to do so, the RAID system as a whole may crash, causing data loss.

Is iaStor.sys a Malicious File?

No. IaStor.sys is neither a malicious program nor harmful. However, malicious software such as trojans and spyware may imitate the iaStor.sys file to avoid detection.

This is especially true if you discover iaStor.sys at a different location other than C:\\Windows\System32\drivers folder. 

To ensure that iaStor.sys is not a virus, run a reputable and trustworthy antivirus or antimalware program to protect the computer from threats.

Fixing iaStor.sys errors

Most errors arising due to iaStor.sys are technically driver issues. Often you’ll need to fix the drivers before such problems resolve.

Use A Driver Updater Tool

A driver updater tool automatically finds and installs missing drivers and updates the existing ones.

This is thought through as the easiest way to fix error messages related to the iaStor.sys file and troubleshooting problematic drivers.

Driver problems are customarily complicated and take a lot of time and effort to fix. Therefore, driver updater tools are the way to go.

Driver updater tools work by scanning your device for driver issues then reporting them to you. That way, you’ll decide how to deal with each one of them as a group or individually. The type of Driver updater tool you select determines whether you’ll sort out driver issues one at a time or as a group.

Note that it is crucial to conduct a system backup before updating the drivers. 

Uninstall IDE ATA/ATAPI controller components.

What Exactly Is Ide Ata Atapi-Controller?

Also known as drivers are “tiny” software programs that enable Windows to communicate with a device’s other software and hardware.

Thus uninstalling IDE ATA/ATAPI components through a device’s manager tool could do the magic. 

Here is a step by step guide on how to do it:

  1. To open the Device Manager, type devmgmt in the search area, then click ‘enter.’
  2. Proceed to the IDE ATA/ATAPI controllers section, then expand it.
  3. When a list of all the available ATA channel controllers pops up, delete all of them, one at a time.
  4. To do this, right-click each one of them and select uninstall.

After successfully uninstalling IDE ATA/ATAPI, restart your PC to reinstall the controller components automatically.

Change The Serial ATA Operation Setting

You can successfully change the SATA operating setting from RAID autodetect. Here is a step to step guide:

  1. Restart your PC, then press F2 before it boots up to enter the BIOS Setup.
  2. When the System Setup opens up, locate Drivers—press enter.
  3. Locate SATA Operation, open it by pressing enter.
  4. When a new list pops up, locate RAID Autodetect/ATA, press enter.
  5. Save changes, then exit the BIOS window.

Manually Update The Intel Rapid Storage Technology

This is the most challenging technique since you must search for the software your device requires. 

To start with, ensure that you know clearly which drivers are required for your system to function correctly. You can use a driver updater tool for this.

Keep in mind that installing the wrong software can cause your system to malfunction further.

Then, in your browser, look for the Intel Rapid Storage Technology (Intel RST) driver installer.

Download and install it on your PC.

Restart your PC for the changes to commence after the successful installation of the installer.

FAQ

Can I Delete iaStorA.sys?

IaStor.sys manages and runs RAID devices. Thus, its removal may have a negative impact on a RAID device. 

Since it is linked to a hardware device on your PC, deleting or disabling it may cause a feature of the hardware device or the hardware itself to stop working.

However, if you are not using a RAID device, then deleting iaStor won’t impact your device.

To do this, delete the file in the directory path ‘C:\\Windows\System 32\drivers folder‘.

Alternatively, you delete iaStor.sys file using the Add/Remove program in the Windows Control Panel.

How Do I Fix iaStorA.sys?

A common and straightforward technique to employ in a bid to fix iaStorA.sys is by use of a device’s Device Manager. Here’s a complete step by step guide:

  1. Type devmgmt in the search area, then click ‘enter.’ to open the Device Manager.
  2. Proceed to the IDE ATA/ATAPI controllers section, then expand it.
  3. When a list of all the available ATA channel controllers pops up, delete all of them, one at a time.
  4. To do this, right-click each one of them and select uninstall.

After the uninstallation, restart your PC to reinstall the controller drivers automatically.

Conclusion

IaStor.sys file is of great importance to users with RAID devices.

However, if it is not in use and you are confident that disabling it won’t cause further harm, it is advisable to disable it.

This is to prevent malware disguising itself as iaStor.sys. 

Suppose you don’t wish to disable iaStor.sys, get your device a trustworthy antimalware.
