HELP: HDDs suddenly not being recognised by Windows

[Keltik THC]

im freaking out guys,

i have 3x 300gb raptors in RAID 0, using the RAID config on the asus P6tD mobo.

Been using it for a month now no problems.

Boot up today and im prompted to insert bootable media.

Ive checked my conections, re-booted a million times and still no joy.

I assume the RAID config has corrupted so i boot into Acronis, but Acronis cannot see my RAID only my other HDDs.

I go into the BIOS and it shows my RAID and says the status is normal and that they are bootable.

any1 got any ideas? windows 7 repair tool cannot see my RAID either.

anybody? 26 views and nothing?

GPARTED LIVE and WD Utility wont run properly when i try to boot.

Acronis only sees my 1tb RE4 backup drive in normal mode, also sees RAID in safe mode, recovered my partition in safe mode but still wont boot.

Windows 7 boots into installation no problem and looks like it will let me install as it can see my RAID, but if the recovery partition didnt boot then i have no hope for the clean install.

im lost, it siwtched off fine last night, Asus RAID config utility says everything is bootable and status is good, but they will just not boot, even when recovered to a working backup from last week.

im all out at sea guys.
