I have an NT 4.0 Sp6 system that I am running out of space on. I need to add a couple more drives. Anyone know a safe (relatively) way to add drives to a mirror set? If so step by steps would be nice.

A mirrored set is just what it sounds like, 2 disks with identical images on them. All you can do is add another seperate mirrored set. If you want faster I/O from the sets back up the data on the first set, create another set and put those 2 sets into a RAID 0-1 and restore the data. This will give you redundency plus faster read write times. I dont believe NT4 supports RAID 0-1 at the OS level. A dedicated RAID controller would be the best way to go. For IDE drives the Adaptec 1200A &2400A would work, for SCSI drives use their 2100S. I hope this helps.
