No update because I haven't gotten the driver installed, or working, nor have I reverted back. Still scratching my head.

As am I. You might call AMD and ask whats up with the driver o.0
I have no clue, perhaps they just aren't very good with support and drivers?
And I thought Asus was bad...

I didn't in my own board, but I've heard that installing the driver before OS install (was for RAID driver, though) was usually best, as well as setting AHCI in the BIOS before hand.

Sorry its not going so well for ya, man

For reasons unknownst to me, the transfer speed seems to have picked up some, so I'm not as concerned about it as I was previously. Of course, that is subject to change.

So the Device manager doesn't list any driver and the driver install failed to install, but AHCI is enabled in the BIOS.

Did the speeds pick up just a little, to a normal IDE level, or a higher level than normal?

something is up if the driver can't be installed... I just don't know what o.0

You might try that RAID driver out.

Come to think of it, I'm not sure what that Marvell floppy image driver was that they have listed, and even though I highlighted it in another post to install, I haven't ever seen something like that before. I had originally thought it was just another marvell driver, I probably would question it before I installed it. Might be a HDD image for the Floppy, but who uses that anymore?

Before transferring the image to the current drive, transfer speed was usually initially ~ 100 MB/s and would drop as the transfer proceeded to ~60MB/s. When I posted this question, the initial transfer speed topped out at ~25MB/s and dropped from there. Now, I'm getting an initial top speed of ~ 60MB/s dropping off. However, the rates are not absolutely constant, and one transfer does better than another.

I'm glad that you mentioned the Marvell drivers again, because that caused me to take another look, and I noticed that the one currently available is a newer version than the one I had installed. When I uninstalled the old one to prepare for the new, it required a reboot, and upon reaching desktop, Windows installed it's own driver, instead of waiting for me. It too required a reboot, after which I checked in the Device Manager, and the first controller in the IDE ATA/ATAPI section is now labeled "Standard AHCI 1.0 Serial ATA Controller", similar to the fashion that your's is listed.

Since the old Marvel driver didn't seem to work properly, I'm reluctant to now install the new one, unless I find that the Windows driver has problems. Therefore, at this time, I consider the problem solved. Thanks for the help.

I just tested it by simultaneously transferring 5 video files from the AHCI drive, to my external video drive, and it topped out @ 113MB/s, then transferred the same files back to where they came from, and the transfer speed showed 210 MB/s. That is better than it was before.

Oops! Something that I had missed. Looking at the storage controllers in the Device manager, it now only show the Silicon Image controller, not the Marvell. I kind of understand, except that I find it strange that the AHCI drive works at all, because it is connected to SATA slots apart from all of the rest, and is on the backside of the MB, and is supposed to be controlled by the Marvell controller.

EDIT: Another thing different, is that previously there were 3 Standard Dual Channel PCI IDE controllers, 3 ATA channel 0 devices and 3 ATA channel 1 devices. Instead of changing one of them as I had thought, there are now 4 of each of those devices listed.

Marvell and AMD should be 2 different drivers for the 2 different types of connector ports that I mentioned in this post (They should be colored differently on the MB: Ahci

You may have known that already. I've heard that Marvell can be a bit faulty at times, as it seems you've discovered. The AMD driver seems like it isn't installing either though. It sounds like you have the OS hooked to the Marvell connector. You might install the newer Marvell driver version for it, and if it doesn't work, then just rolling it back.

If the generic drivers work best, why not?

I will admit that I can easily get confused with all these chips and drivers, but what confuses me most right now, is that the drive connnected to the Marvell slots is working with the Silicon Image controller. At least, I'm assuming that is so, since it seems to be the only possibility, since neither the Marvell or AMD drivers are installed. Yes, I am considering installing the new version of the Marvell driver, but considering how well things are working right now, I'm not in any hurry. I'll at least wait until I'm in the right frame of mind.
