Windows 2000 Server RAID5 problem.

Windows 2000 Server RAID5 problem.

I have 4 HD for data only, one of them (disk1) has data, others are empty.
In case of not affecting the data, is it possible to create a RAID5 system
with these 4 HDs?
Since I have tried to do so, however, it only provides the mirror option
with I right click to the disk1.

In another case, if I first create a RAID5 system with the other 3 HDs,
copy all the data from disk1 to the RAID5, then delete the disk1 partition.
Finally, Is it possible to add additional HD (disk1) to the existing RAID5
system with 3 HDs?

In RAID5 system with 3 HD, what will happen if one disk is failure?
How about RAID5 system with 4 HD, what will happen if one disk is failure?

Because all of these are the company server's HDs,
so, I am not convenient to test the cases above.
Please share your experiences and knowledge if anyone could help me.

Thanks.
