Hey chaps,

I have a similar problem to this, http://www.pchelpforum.com/hard-driv...d-problem.html hope you don't mind if I ask it here. Im also having hugely annoying RAID issues on an msi motherboard (770-c45).

Basically, in the BIOS under 'On-chip ATA Devices' there is an option marked 'Raid Mode' from which you can select either IDE, RAID or AHCI, as has been mentioned above. If you select IDE, everything is fine, but of course there is no RAID functionality. If you select RAID, there is the usual create array setup options, BUT with this mode set the BIOS no longer recognises any SATA drives (although the raid setup screen does). And niether does the computer- the non-Raided SATA drive that windows is on does not load, the acts like it has no drives (actually, the windows loading screen appears for a second, then the comp restarts).

Basically, the computer wont boot windows from a single sata drive unless IDE mode is selected in the BIOS. It seems like the onboard RAID allows for no raid, or ALL sata drives on raid, it doesnt seem to allow some on raid and some not.

CeltiExileOnline- can you just confirm that this isnt how it works with you? That when you have selected RAID mode, the comp still boots windows from the non-raid drive? Also, do your sata drives show up in the BIOS when raid mode is selected?

Thanks very much. Im also not impressed with the msi support on this. It mentions practically nothing on raid, and neither does AMD, who actually made the chipset!
