I do not have open array manager software and rely on the scsi utility that presents itself suring boot time. I want to add a 4th drive to the existing raid 5 configuration. Will the utility destroy my exisitng data? Does anyone have insights to using the utility program? Windows server 2003 on a dell system with an adaptec controller card.

Yes, you will need to follow these proceedures:
1. Make a tape backup of all your data
2. Make a second non-tape backup of the critical data (just in case - copy the data somewhere else).
3. run your raid configuration utility and delete your current array
4. Create a new array with the extra disk
5. Re-install your OS - if you have one button restore on your tape then you can use that to recover.

If you DON'T want to do that - you can make a second array. You'll need at least 2 disks for a Raid 0,1 and 3+ for Raid 5. This will be a second storage space.

YES!

ANYTIME you try to do a major change to your data you need to do a complete backup.

Adding a drive to your system is going to change the physical structure of the data storage.

Even if you have an advanced raid system that provides this capability consider the chance that murphy will come and visit during installation.

You don't need to do pretty much anything. Adaptec should recognize your drive just fine. Once in Windows 2003, go to Disk Management utility and add the fourth drive to your existing configuration. I'd certainly do the backup prior to changing anything, as previous answer suggested.
