Hello,
Now if U really need the data, U should not try to remount it using the raid controller. In fact U should never give Windows a chance to mount a damaged partition.
In this case (though U haven't mentioned the RAID level the disks were running) I suppose it was striped (RAID0).
I think U should first diagnose the damaged disk and make an image of it to a known good drive, if even it is possible.
Then U may continue with SW recovery.
If U are unfamiliar with theese things, I definitely suggest to take the set to a specialist.
edit: now I see the topic shows it is a RAID0

sorry.
regards,
pepe
