It should only be necessary to open Intel® Rapid Storage Technology software, click the Accelerate tab, click Stop Acceleration, and click Reset to available.
It is expected to get a Blue Screen of Death when you change the SATA controller from RAID to IDE or vice versa, because the operating system was installed in that mode. You may need to reinstall the operating system if you really want to change the SATA controller mode in BIOS.
However, it is possible to delete a RAID volume connected to an Intel® Chipset by pressing CTRL + I during POST (before operating system starts booting) and select Reset Disks to non-RAID in the RAID BIOS or RAID option ROM. No data loss is expected but it is advised to create a backup.
Thank you for your reply. Unfortunately it's of no help / not applicable to me, for the following reasons:
- there was no Accelerate button/tab in the IRST GUI, ever (which is why the cache never worked, I guess). But the GUI did show the SSD and I did set it to "Available"
- the OS was certainly not installed in RAID mode - the RAID only appeared with my installation of IRST, i.e. IRST set up the RAID after years of that machine's running in IDE
- Ctrl-I during POST does nothing: no RAID BIOS or RAID option ROM appears, the boot happily starts Windows without stopping.
In short: IRST installed a useless RAID on my machine, probably because the machine's chipset doesn't support it. I think that the IRST installer should have detected the condition and simply not install at all - but in any case, I want to get rid of it now, and I'd find it inconceivable that the only way of getting rid of it would be a complete reinstall of the OS from scratch?? That would really be reckless on part of IRST.
Here is what Device Manager reports:
- could you suggest any other way of dropping the RAID and revert to IDE? Like "Uninstall the driver", maybe??
Many thanks for your help!
Did you change the SATA controller mode to RAID in your system BIOS when you tried to use Intel® Rapid Storage Technology? If the answer is no, your system should not have a RAID volume created.
It seems that the operating system became corrupted. You may want to restore your system to a previous date before Intel® Rapid Storage Technology was installed.

No, I did not set a RAID myself (never even thought of setting one up!) - I was flabbergasted when it appeared on my machine after the IRST installation.

Of course I tried that, to no avail: going back enough in time, the restore uninstalled not only IRST's GUI, but also applications that were installed before IRST... but the disk nevertheless stayed "Controlled by RAID" 8-O. And when I subsequently tried to switch to IDE in the machine Setup (POST, as suggested by the "removdrv.txt" document), the result was BSOD during Windows startup - only switching back to RAID in POST made Windows start again properly (as I explained in my original post).
I do not think the OS is "corrupted", because everything else works just fine (and every disk check turns out ok). But anyway, I have now successfully moved the contents of my HDD to a 512GB SSD (including the bootable OS), and have the two disks working fine in the machine. They are both still controlled by the RAID (given that I can't get rid of it), but it doesn't seem to be doing any harm, so switching to IDE became a moot issue - I'll simply keep the RAID, hoping it will be ok in the future.
But still: not being able to undo IRST's fiddling with my machine without a total reinstall of everything looks extremely inelegant to me.
Thank you for your help!
Thank you for your followup, joe. Unfortunately, I already did the Registry modification to "Start 0" - but still got the same Windows startup BSOD after switching from RAID back to IDE. It's pretty mysterious... but as I said, the machine is now doing what I wanted, so I'll leave it as it is.
