    Mobile Express Chipset SATA RAID Controller (iastora.sys) corrupt on boot


      Running a Dell Latitude E7440 on EFI + SecureBoot + Windows 8.1 + BitLocker and I randomly get start-up issues where the OS is flagging iastora.sys as corrupt.  With no action taken I can choose to continue to boot through to Windows and it works fine.  It doesn't happen every boot, but when it does the SrtTrail.txt log file contains:


      Root cause found:


      Boot critical file c:\windows\system32\drivers\iastora.sys is corrupt.


      Repair action: File repair

      Result: Failed. Error code =  0x2

      Time taken = 2188 ms


      Any thoughts on what might be causing corruption?  I have tried installing the latest chipset drivers and that has not resolved the situation.

          This file is part of the service of Intel® Rapid Storage Technology. This software provides the capability to set RAID volumes on the computer depending on the Computer Manufacture limitations.


          If your system is running a RAID volume, you can try uninstalling and installing the Intel® Rapid Storage Technology driver. My best recommendation is to get the driver and support from the Computer Manufacture since your system has many special features such as the Bitlocker.
