Working on a compaq proliant 1600 4 hard drives windows 2000 and exchange 5.5 fully service packed. Running a raid 5 with the Compaq Array utility and just one large drive as a basic disk. Windows is broken into 2 drives C: for OS and D: for priv.edb and pub.edb. I want to add an extra hard drive into the configuration without having to restore the data. Is there any possible way of doing this?
