I've been having a real nightmare trying to get my 965P-S3 (i.e. not DS3) to recognize all my SATA/IDE drives reliably. I have 3 SATA hard drives and 2 PATA DVD writers in the system. The symptoms vary all over the place so it's really hard to narrow down the cause. Sometimes after a cold boot (I usually leave my machine off during the day and power it up at night), one or more of the HD's just won't be there in the BIOS. This happens about every other day. Other times, a drive will just disappear in the middle of some activity in XP, often causing a blue screen. This usually happens during heavy multitasking, usually in conjunction with some kind of multimedia app running (media player, dvd player, jpg viewer).
The wierd thing is that, once a drive has disappeared, nothing seems to bring it back. Even a cold reboot doesn't help, though I suspect that if I left the system off for an extended period (several hours) it would change things. About the only thing that can resurrect the missing drive is to physically move the SATA cable to a different controller for a while, until it eventually fails there, then move it back. The *really* wierd thing is that I've even tried installing a third-party PCIe SATA card based on a totally different chipset (Silicon Image SIL3132) which has its own BIOS. This card seems to have been "infected" by the same problem!
I have tried every combination of drives and controllers I can think of (to the point where I'm concerned about wearing out my SATA cables). The most reliable configuration so far has been to put the HD's on the ICH8 and the two DVD writers on the JMicron PATA port (I have tried IDE->SATA converters but they don't help). The HD's are a Maxtor 6B300S0, Maxtor 7L300S0, and a Western Digital WD4000KS RE16. The WD seems a bit more reliable than the Maxtors but I've had it disappear as well. The optical drives are a BenQ 1650 and Sony G120A (OEM Liteon 165P6S)
Has anyone else had a problem like this? I have the latest S3 BIOS (F6) which has the same release date as F7 on the DS3. I've heard that the DS3 beta BIOS (F8i) has updated firmware for the ICH8 and JMicron. Does anyone know if it's safe to use DS3 firmware on the S3, or if it will help?
I'm running a non-overclocked E6600 with 2GB of Patriot DDR2 667 memory. I don't know what chips these DIMMs use but I'm not OC'ing so I'm hoping that doesn't matter.
I've tried swapping power supplies, which didn't help. Right now I'm running Memtest86. If that doesn't turn up anything, I'm wondering if it's time to RMA this dog.
