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.
