Windows Boot stalls when adding additional Sata Drives

[SirTenTea]

I've recently reinstalled Win7 64bit to my Mushkin enhanced Deluxe 240gb SSD. This drive had a missing MBR. I was finally able to reformat it and install Windows after changing the boot to Legacy Only in the Gigabyte BIOS. After installing all the updated drivers and video drivers in the new install I turned to re-connecting all the other HDs in my build that were there before the original problem occurred. These drives are a combination of SATA II and SATA III and worked fine on this build before my MBR problem. That's when the boot of windows stalled. I the tried connecting one at a time (There are 7 additional internal HDS) with the same results. The BIOS did see the one additional drive I reconnected on the second try. When I go back to the single drve everything is fine at boot. I even changed the boot back to UEFI and Legacy, thinking that was the cause of the problem. I'm at a loss to understand why these drives don't function in this, my second installation of Windows in this build.

Some System Info:

I also have two External drives connected with no problems at boot. If the BIOS saw one of those drives how come even that one additional drive causes Windows to flake out?

Well mate the only thing I can think of at the moment is to check the Device Manager and see if they are there and any error triangles alongside.

Perhaps you need to update the driver s these particular drives and personally I use the manufacturers for that as I am not a fan of the Windows feature.

No error triangles in Device Manager to be found. How does one use an updated driver for a Hard Drive that's not connected to the system? Yes, I don't find Windows to be very efficient in finding updated drivers for much of anything.
