BIOS 1005 caused dropouts of the DiamondMax10's. I could only fix it
by doing as described above - that is, going back to 1002 then up to
1003, with CMOS reset.
BIOS 1006 (NVRaid BIOS 4.81) also caused dropouts of the
DiamondMax10's after about two reboots. I could only fix it by doing
as described above - that is, going back to 1002 (NVRaid 4.79) then up
to 1003 (NVRaid 4.78), with CMOS reset.
This problem is not getting fixed by ASUS.
This is clearly a bug in the Nvidia RAID BIOS.
In BIOS 1006, only one of the DiamondMax 10's would show up connected.
However, I could physically remove one of the two DiamondMax 10's,
yet no matter which I physically disconnected, the RAID BIOS always
showed the remaining drive on the same connector.
In previous iterations of this problem, I have noticed that removal or
reconfiguration of other drives on either the Nvidia RAID SATA or the
NVidia IDE connectors would sometimes magically trigger the appearance
or disappearance of one or both of the DiamondMax10's.
This indicates that the issue is configuration dependent, which may
explain why some users never have a problem...
The other thing that bugs me is that downgrading the BIOS from, say,
1005 directly to 1003 will NOT fix this problem, even with CMOS reset.
I MUST go down to 1002 first to get both Diamondmax10 drives back. I
can then upgrade to 1003 without the losing the drives. This
indicates that there is some "memory" to this board - i.e. reflashing
the BIOS and resetting CMOS does NOT completely reset everything to a
fresh factory state...
I'm the one who wrote the message immediately above. I emailed Maxtor
and Asus about this problem. Asus has not repsonded after two weeks.
Maxtor replied the next day, and emailed me a new firmware for the
DiamondMax10 300MB drive(s) that I have.
To make a long story short, I upgraded (or downgraded - not sure what
they sent me) the firmware on both hard drives. I was then able to
upgrade my A8N-SLI BIOS to 1006. I have been running the system for
about three days now, and on every POST both of my DiamondMax10 drives
show up just fine with no problems. I'll feel safer after a few weeks
have gone by, as it worked for about a day previously, but I do feel
that this fixed the problem.
I have to say, though, woe to the user who has to upgrade the Maxtor
BIOS. I had a heck of a time. The drives were not visible to the
Maxtor utility when connected to the Nforce4 controller (the readme file
says this, too).
I then connected the drives to my Silicon Image 3114 controller on the
motherboard, and although they were visible at POST, the Matrox utility
could not find them.
I then (luckily I had this as a spare) installed an old PCI SATA
controller with a SI3112 controller on board. I then disabled both the
motherboard SI3114 and the NForce4 SATA & IDE, to ensure that the SI3112
BIOS could load. I connected the first DiamondMax10, and the Matrox
utility found the drive. It also warned me that the firmware on the
diskette did NOT match the drive type, and would ruin the drive. I had
seen a posting on the web elsewhere to ignore this warning, which I did
and went ahead with it anyway. The burn went fine and confirmed. After
reboot, the Maxtor utility could NOT find the drive anymore, and neither
could the 3112 at POST.
I was worried at this point, but plowed ahead with the other drive next.
I removed the just burned drive and replaced it on the 3112 with the
second DiamondMax10. This drive was identified at POST and by the
utility, burned fine and confirmed. After reboot, POST saw the drive,
and the Maxtor utility could see the drive, but could NOT list the
firmware info on the drive.
I put both drives back on the NForce4, reenabled in the BIOS, and fired
away. Windows XP loaded up just fine, and NVRaid did not complain of
any problems (my DiamondMax10's are in a Mirror set). I then updated to
BIOS 1006.
I have not had a problem since (3 days).
Anyone having trouble with the DiamondMax10 drives on the A8N-SLI, I
encourage you to email Maxtor. I then wish you the best of luck in
actually getting the firmware burnt to the drive!
