System:
X58A-3udr Gigabyte mobo
I7 - 920 no o/c
6Gig Crucial 1066 RAM
JBOD including two Barrcuda XTs SATA-III
Crucial 300 SSD as boot on SATA-II
Please read this if you have time and tell me if I have to do what Gigabyte says! Sorry for the wordy post but I thought the details and order were important.
I have been posting positive comments about my mobo choice for a March build in a HAF932 case: a rev#1 X-58A-3udr unit from Gigabyte. I made a mistake in March and loaded Win7-64 under IDE. I used the machine for a while but had always hoped to re-install.
Well, this last ten days Gigabyte took so long to respond to a question (almost a full week) that I will (according to them) have to reinstall AGAIN and re-do all applications, utilities, Mozy backup, everything. This is a production machine for my imaging work, not just a hobby, although I enjoy making everything work welll together. I started on the IDE-AHCI switch and necessary re-install a while ago to be ready for my next professional project. Now the beginning of that project is close, so I am going to have to give up some important other community volunteering and reinstall AGAIN.
When this all started I resolved to be careful. I studied their site and the supplied 136-page mobo documentation and carefully changed several settings in the BIOS to insure AHCI. I watched boot screens carefully to make sure I had a completely AHCI - enabled disk I/O. (I photographed the fast-paging screens to make sure I could read the lists.) However, the Mavell chip-driven SATA-III connectors (there are 2) kept displaying on the same page as the IDE scan. Only if I moved the connectors to the SATA-II run by the Intel chip would they display during boot as AHCI.
So I sent a message to Gigabyte asking why, and noting all the system info. Yes, there are BIOS updates but I told them I'd do those after the re-install (I don't like changing too many pieces at once) unless they knew that an update was required for the moves I was making. The first several answers were garbled and didn't answer my questions. After some back and forth I replied finally that they were "not reading carefully enough" and the next answer was composed in much better English. (I know they are in Taipei but the tech staff handling the English-speaking world ought to be better trained.)
This better-written answer said I could not move any connectors after an install. However, the response (yet again) did not answer the lingering question about why the SATA-III connectors still look like IDE to the boot process. This makes me CRAZY.
By this time I had re-installed the OS with all the SATA connectors attached to the Intel-driven I/O, SATA-II, which was the only way I could get an all-AHCI boot. I left the Marvell and Gigabyte-driven SATA connectors empty, figuring that I could switch them after all drivers were loaded. I knew I had everything as AHCI during boot. Nothing in the docs says I can't do this and I have never seen a reference to connector-move-restrictions reading hundreds of posts here on Tom's. Yes, I could have missed many such references, but I read a lot and thought I could do this. Arrrgh.
So-Now that I had Win7 running, with all apps reloaded, I moved the connectors before I saw the tech response saying I could not do so. The Barracuda XTs went to the SATA-III. I added another drive to SATA-II, a WD Velicoraptor that had been the boot for this system but which had an MBR problem and was to be wiped for use as a scratch disk in Photoshop.
I saw no operating problems with the connectors moved around as I want them. However, I immediately again saw the SATA-III HDs on the IDE page (first) in the boot screens. The machinery all looks OK in Device Manager, but I do not know how to interpret the "Location" parameters shown for each HD in the Properties. I suppose I could re-install the Marvell driver (I am using a newer on posted on their web site) as a hopeful move. I should try reading and writing some big image files to test I/O speed on what I expect to be SATA-III but I don't have a "before" number to compare them to for SATA-III proof.
But I sure want to avoid the time sink of going through the whole process again. CS4, Photoshop 5, Office 2010, PaperPort, OmiPage, many little utilities, yada, yada, yada.
1. How do I get all these drives attached through AHCI? All BIOS settings are right.
2. Why are the Marvell-driven connectors resisting AHCI assignment?
3. Why do I have to re-install Win7-64 if connectors move?
Comments, anyone?
