Windows 7 64bit PC with 3 x 3TB hard drives no longer boots in AHCI mode after installing "Intel Mat


Honorable Member
I successfully installed Windows 7 64bit in AHCI mode on a PC with 3 new 3TB Western Digital WD30EZRX Caviar Green hard drives.

Then I installed "Intel Matrix Storage Manager Driver [v8.9.0.1023]" & as soon as Windows restarted after installing it, Windows would not boot, & will now only boot in IDE mode.

In IDE mode I have to do a system restore to the point before installation of "Intel Matrix Storage Manager Driver" to be able to boot again in AHCI mode.

I have not had this problem before with 2TB/1TB hard drives.

Does anyone have any idea what's going on here?

This issue was resolved by installing "Intel Rapid Storage Technology [v10.1.0.1008]", it seems that 3TB hard drives are not supported by "Intel Matrix Storage Manager Driver [v8.9.0.1023]".
