extending RAID5

I have 3 SCSI drives 36.4GB each and they are configured as RAID5, I want to add another 36.4 GB to extend the space.

I went to array config utility it shows a menu:
Create logical drive
view logical drives
delete logical drive

in create logical drive when I move with the tab (button on the keyboard) it doesn't go to RAID5 all it goes to is RAID0.
I wonder how can I extend the disk space?

any help?

thanks

If all you have is the 3 drives as a RAID5, you'll need to delete and recreate the array as a RAID5 expanding onto all 4 disks.
Obviously this will probably mean a rebuild of your OS, if this is where it's installed...

Yes I have 3 free slots and 3 scsi drives of 36.4GB, in this case how would I create another separate RAID5?

excellent.

I have created a new logical partion through Array Utility.
in windows explorer the drive doesn't show up. I went to disk management and it asks about write signature (do you have any idea what this means?).
anyway I created write signature, then it asked me about primary or extended partition (do you know what this means?)

thanks

Yes, you need to format it - format it as primary and you should be all set. :^)
