I apologize in advance for my lengthy message, but I wanted to provide as much detail as possible with the hopes that someone might be able to help me resolve my problem with Intel RST.
My PC hardware is standard for using IRST – a hard drive plus the caching SSD. Here are a few details:
Intel Core i7 3770 CPU
Gigabyte Z77X-UD3H motherboard
WD VelociRaptor 300GB with a Crucial SSD
We lost power two weeks ago, and I wasn't able to get all PCs turned off before they went down hard. One of the machines (Windows 8) that went down hard, when it was rebooted a message came up stating that the BIOS values were being reset to the defaults. At that time, I didn't think about the RAID setting for the drives not being set properly. The PC booted and seemed to function normally, and I continued to use it for remainder of the week.
The following Monday, I shut down this PC and when rebooted, it wouldn’t come up correctly. I now recognize that this was due to the drive type defaulting to AHCI instead of RAID. It appears that running it in the wrong mode caused some file corruption. After a bunch of repair attempts, using the Windows tools, trying to roll back to an earlier restore point, and moving the hard drive to another machine to do a disk check -- I was finally able to get it running again. However, I had to disconnect the SSD in order to make it work, and anytime I reconnect the SSD, it doesn’t boot.
The problem is with the accelerated drive feature in Intel RST. I now have the machine running, but I want to free myself from IRST acceleration and want to use an SSD as the primary drive. Here are the problems I have run into:
- IRST is running and it appears in the system tray. Launching IRST fails with this error message "An unknown error occurred while running this application. If the problem persists, please restart your computer or try reinstalling the application."
- I have tried to uninstall IRST, but it won't let me stating the drivers are in use.
- I have tried to install a newer version compatible with Windows 8, but this fails.
I have tried to gain access to the IRST "ROM" that comes up before the OS, but using "Ctrl-I" never works, so I can't reset the disks to non-RAID. I don't know if it is running or not because I have the RAID turned off.
After reading a discussion about a related problem, I thought I should turn the RAID setting back on in the BIOS, but the won't boot in this mode. I went back to AHCI and after a disk check, it booted back up.
I’m hoping to avoid reinstalling the OS on a fresh drive. I would sincerely appreciate any help freeing myself from the IRST accelerated drive configuration.
