Thank you for joining the Intel communities.
I understand that the Intel® Rapid Storage Technology crashes, but I still don’t know how does it crash?
Do you get any error when crashes? Could you please POST a picture when it crashes?
Unfortunately, no error messages, again the flows is - flash install Windows 10, install iRST, enable accelerations, after enable acceleration, as long as not "Restart" Windows, "shutdown" will not cause the crash. (I can shutdown the Windows 3 time without any issue.)
But once "Restart" Windows, Windows will "shutdown" normal and Lenovo logo back on and immediately will show "Diagnostic"... "Fixing"... and then option like "Shutdown" "Advance troubleshooting"... system is done.
At this stage, nothing I can do, make it worst, flash install Windows (Clean all partition on 500Gb) will not work until clean all partition on SSD under AHCI and install Windows ONE more time. This is the last clue I can shared - which means something wrong in the boot sector from SSD - link to iRST Raid causing is error. But again the SSD is not defective.
Also restore Windows (restore point create before enable acceleration.) is not work, which means the error layer is very close the boot sector.
Sorry Ivan, I will not going further diagnostics on this, I just want to shared my case for others to shorten their diagnostic time if they saw this happen.
