MSI RS480M2/Raptor 74GB performence issue

[StoneNewt]

My MSI RS480M2-IL & Raptor 74GB is giving extremely slow SATA HDD performance & stalling processes during read/writes, this is almost reminiscent of PIO mode on UATA drives however this is an SATA drive (do SATA drives even have PIO mode?). So far I've swapped SATA channels, cables, PSU & power connector type but to no avail, I have a 200GB drive which I could use as a system if needed but I'd prefer to use the Raptor. I'm wondering if other people have experienced this with this mobo/drive combernation.

I suspect it's a driver issue over a hardware issue. Check your chipset drivers and try uninstalling/reinstalling them.

Well I've installed them after all the patched etc and on a fresh install before everything else and the same thing is happening.

I don't know if you've resolved your issue. I had a similar issue with my second 74GB Raptor (and still have). I was getting 100% CPU and *extremely* slow disk performance on my second Raptor (eg. when cleaning the disk, un-rari'ing large files, etc.).

This had me baffled for a while. At one point the second drive was not even detected reliably on boot. I eventually traced the problem to an issue with the SATA power connector on the drive itself. I unplugged the SATA power connector and used the standard 4-pin molex power connector and things have been fine since. (<-- very important as you can only use one of the power connectors on the drive: the SATA or the legacy 4-pin molex).
