win8 and amd sbxxx raid 5

Windows 8 doesn't appear to recognize my amd raid 5 array. The disks are seen as single disks. If I delete the raid 5 and create a RAID 0 or RAID 1 array w8 recognizes the array. Raid 5 also worked under win7. What up?

RE: win8 and amd sbxxx raid 5

Is it hardware array or software array?

Re: win8 and amd sbxxx raid 5

SBxxx onboard arrays are software RAID. (not OS software RAID, but all RAID work is done in software). It is very likely that W8 shipped with an AMD RAID driver that doesn't support RAID5, i.e. doesn't recognize the RAID signature and considers disks as single disks. (this can also happen if you install an incorrect driver for your motherboard) "George M.

I installed the w7 x64 AMD AHCI compatible RAID driver from the motherboard manufacturer's web site and RAID 5 magically started to work. One problem though, when I enable AHCI (instead of RAID) in the BIOS w8 crashes during boot. This is true both for the AHCI driver that ships with W8 and the w7 driver from the manufacturer's web site. Where are we supposed to file bugs so this can be fixed?

RE: win8 and amd sbxxx raid 5

"when I enable AHCI (instead of RAID) in the BIOS w8 crashes during boot" MS overlooked this issue badly. Not as bad as 137GB fiasco in XP, but still bad. If you install the OS (Win7 or 8) when the controller is in legacy SATA mode, only the ATA driver will be loaded at boot. If you switch the controller to AHCI, the driver will not be loaded and you get a 7E bugcheck. There is a KB article for that.

Re: win8 and amd sbxxx raid 5

>to AHCI msahci.sys is a disaster. It still hangs from time to time, even in Win7 SP1, blocking all disk IO for ~15 seconds, due to some race in it. And the fixed version is _unavailable for downloads_ (though exists) and the customer support service ignores all emails requesting it. -- Maxim S.
