RAID 0 with two dummy disks

[TiTex]

Hi,
I never had to do this so maybe somebody else can help me out

I have server (although it's a windows server) and there are 3 hdd's on it , the problem is that who installed the OS configured the disks in a RAID 0 array but only disk1 is active , so every information is written to disk1 the other two are just sitting there.

My question is , can i remove the disks from the array (destory the array) and boot normally from disk1 without having any information loss or corrupting the OS ?

Thank you!
