I had 3 disks in a hardware Raid 5. I have added a 4th disk. I have rebuilt the array and can see the additional space. On the array I have 4 GB for drive C: and the rest was drive D: I now want to add the additional space to D:. Can I do this without deleting D:, recreating the partition and restoring the data? I am running NT 4.0 with SP6a.
Thanks,
Ed

Yes, it is possible. But that depends on your RAID controller. Most RAID controllers do support this. Read up on your RAID controller, some require a certain piece of software to do this. Good Luck!

Yes, you can add the space to the D: drive but it will make it a volume set. No need to delete the D: drive.

I don't think you can achieve this with HW Raid. That will just give you extra space to play with (eg to create an E: drive). afaik the only way to do this is, as shariff says, is to use NT's software raid. If you don't want to do that you'll have to recreate the HW raid (as one disk) and then restore from tape!
