RAID modification question

[Guest]

I have a RAID 1 array on a Win2K Server and need to add a third drive to
obtain a RAID 5 array. All 3 drives are identical.

What's the safest way to do this so that I don't run the risk of losing
anything? Should I just use tape backup or is it better to use partition
management software?

Thanks much for any help.

Safest way would be a full backup of the data, as RAID5 will require writing
over some or all of the existing RAID 1 disks.

Though, if you can get a hold of another disk, you can keep one of the
original RAID 1 disks as the back-up, set up the RAID 5 with the other RAID 1
disk and 2 others, then transfer the data from the back-up RAID 1 disk.
