I have a sata drive:
WDC wd800jd-75jna0
I'm running it as OS drive
it all seems to be werkin fine so far.
This is very similar to my spec... but I've also had a lot of the dreaded freezing, with accompanying click (doesn't your blood run cold when it clicks like that
), and "An error was detected on device \Device\Harddisk0\D during a paging operation" in the event log.
However, I think I've solved it, and it's turned out to be completely unexpected, albeit obvious in retrospect.
Spec:
Asus A7N8X-E deluxe
AMD Athlon XP 2500+
nVidia nForce2 Ultra400 chipset
On-board SATA controller - SiI 3112a
Here's the story...
One of my original IDE drives died, so I replaced it with 2 x 200 Gb Maxtor DiamondMax 10 SATA. Installed XP Pro SP2, included the SiI SATA RAID controller at the "f6 to load 3rd party SCSI controllers" prompt, all fine, both drives recognised, mirror set built, all cool.
In use a couple of weeks later, on a reboot, and a message from the RAID controller to the effect that the RAID set had dropped out.
. Anyway, rebuilt using the "f4 to configure RAID" thingy, just before Windows starts up. All fine, no data lost. It happens again, a few days later. And again, a few days after that. Several times in fact, the intervals getting shorter and shorter.
So I break the RAID set and use the drives independently. Ok again for a few days.
Then the clicks start. Disks aren't supposed to make that noise... messages in the event log looking very ominous.
They get more and more frequent. Games become unplayable, though no data actually seems to be lost. (Meanwhile I'm searching the forums, looking for alternate drivers, anything in fact, that would make sense of all this).
Eventually, the paging errors get so frequent that the PC is unusable. Deterioration like this can only be dud disks, right? So I buy an IDE drive, and rebuild the whole lot. I have a working PC again. All set to return the SATA drives under warranty, but then...
... I discover that in the frantic DVD-burning that took place before the thing became a completely useless heap of junk, I missed a few things out of the backups - doh! So I figure that with a stable machine, I'll have a go at recovering some data from the dud drives. With all the cabling in the PC now neatly routed, I didn't want to pull it all out again, so I pull a molex cable off the DVD-ROM to power the SATA drive, which I run leaning against the PC with the side off. Precarious, but it's only gonna be for a few minutes.
The drive works perfectly. No clicks, no events in the log, perfect.
Bottom line: both SATA drives are working perfectly again. I can change the BIOS boot sequence and boot off them, install and run Far Cry off them, they're fine.
So WTF was going on?
I now think that the PSU was simply overloaded, or one of the 12V rails was, anyway.
Originally, I had one of the 12V outputs from the PSU going to the optical drives, and the other to the hard drives (two IDEs at the time). And the graphics card which has its own molex socket. And a case fan. And the CPU fan.
And what did I do? Duhh... I took out one HDD, and replaced it with two more. So that PSU output (with various molex splitters that had somehow accumulated over several years) was now running:
- 3 x HDD
- graphics card
- 2 fans
:tears:
The other one, of course, was running a big fat nothing, since the optical drives and floppy are taking no power at all most of the time.
So I've reinstalled one of the SATA drives, using the connection off the PSU that was running the optical drives. I very rarely have the DVD-ROM and the DVD-RW going at the same time, so their power just comes from a splitter, leaving one connector for the SATA drives.
All working fine now. I've also run it with both of them back in, all mirrored up - also fine, but they were too close together and consequently a bit on the hot side. So I'll rearrange the drives in the cage to leave a nice gap when I can work up the enthusiasm.
So the moral? Get a PSU with enough grunt, or at least make sure the load is distributed properly.
