OK, my SSD arrived so it’s “Time” to set AHCI mode before migrating to the SSD.
Where I’m at…
HP d5000T Pavilion Elite Desktop.
ASUS IPIBL-TX MoBo, Q9450 CPU, 8gb of system specific RAM
OS is a stable (15month old) installation of Windows 7 Professional x64 that I am NOT willing to give up on (Suggestions that I reinstall windows from scratch are so profoundly unwelcome as to defy my specifying them in detail)
Current system drive is a 100gb partition on a WD Black 500gb
making a system image and mounting that image to a new drive
I have a handle on…
Where I’m having a problem is switching the SATA controller
to AHCI mode.
I’m currently in RAID mode.
I’ve tried the Regedit in localmachine, (brevity prevents my repeating it in detail) changing the parameter from “3” to “0”, which was a complete waste of time as that parameter was already set to “0”…
I already ran the Microsoft Fixit (http://support.microsoft.com/kb/922976)
suggested by Dee, still no go…
When I go into setup and change the SATA controller mode from RAID to
AHCI I get a flash of a BSoD then an invitation to run Startup Repair
I’ve both let it run it’s course (and it says it can’t fix it) and chosen a system restore (equally useless) and the only thing that makes the system restart is changing the SATA controller mode back to RAID
I’m doing all this to a CLONE of my system drive that works perfectly
(I’ve been running it for a week) but I really don’t care if I screw it up
I can switch back to the primary drive and have a working system just by moving a sata cable…
I really want to set AHCI mode BEFORE making a fresh system image and before swapping in the SSD
but so far all attempts have only succeded in raising my blood pressure.
What is really going to drive me nuts is if I don’t NEED to switch to AHCI at all…
because several explanations of AHCI say that RAID enables it just as well…
I just want to be sure that TRIM works because an SSD without TRIM is like
a Ferrari without Lube oil… it’s a laugh riot… until the engine seizes… after that, not so much…
