Windows 8.1 Pro - High CPU usage from Intel process IAStorDataSvc (32 bit)

I have just installed the Windows 8.1 Pro upgrade without problem and it seems to be functioning perfectly.

However the Intel process IAStorDataSvc (32 bit) is running continuously with 30%< CPU usage and 60% Memory.

To stop this I have to select End Task but each time I re-start the laptop the Intel process automatically starts.

My Laptop is Sony VPCSB Intel Core i7-2620M CPU @ 2.70Ghz with 8Gb RAM and 226 Gb RAID SSD storage using Windows 8.1 Pro 64 bit OS

Can anyone help with a solution please?

Thanks Guy

    Hi Guy

    Hi Mi

    I just went and did the Vaio update and it automatically brought up the 3 drivers referred to.

    You can also do it via the Vaio care desktop utilities.

    Let me know if you need more?

    Cheers Guy

    Hi,

    This is known issue faced by many customers using the Intel Rapid Storage Technology. Many users have mentioned facing this issue when using the driver version 11.5. Most of them have reported that the issue was resolved after installing the latest drivers for this technology. So, I would suggest you to install the latest driver from the manufacturer’s website and check if that helps. Since you haven’t mentioned the fill model number of the computer, you can search for the driver for the correct model here:

    If you are unable to find the appropriate driver from the manufacturer’s website, then I would suggest you to check the Intel website and download the latest Windows 8/Windows 8.1 compatible driver and check:

    Try these steps and let us know the results. We’d be happy to help if you need any further assistance.

    Hi Ben,

    Downloaded 3 drivers from Sony Asia, IAStorDataSvc now fixed. thank you.

    One of the drivers was for the Intel Bluetooth.

    Hi,

    I am having the same issue.  I went to the Intel site and downloaded their tool to identify out of date  drivers and it indicated that I had the most recent driver.

    After upgrading to Windows 8.1 the process IAStorDataSvc is consistently taking  up a lot of CPU.

    What is my next step for fixing this?

    Thanks,

    ... Brad

    Hi Ben,

    I ignored the Intel driver tool and downloaded the latest IAStorDataSvc driver.  I read  the readme.txt file and my disk controller was not listed in the overview.  I ignored this as well and went ahead and installed the new drivers.

    This did solve the problem.  Thanks!

    This will be a nasty problem for some users when they upgrade to Windows 8.1.  Many users won't know how to check CPU usage and their experience will be that Windows 8.1 is much slower than Windows 8.0.
