I am unable to partition my T4 RAID 5 drive in Disk Utility?

I am unable to partition my T4 RAID 5 drive in Disk Utility?

If you are having difficulties erasing and partitioning the T4 (RAID 5) in Apple Disk Utility, please try to create a new RAID 0 set first, then re-create a new RAID 5 set.

The following steps show you how to create a new RAID 0 and then re-create a new RAID 5 set.

1. Go to the CalDigit Drive Utility (CDU).
2. Click on ”Disk Utility” from the CDU menu.
3. Select “Delete RAID set” and click on the ‘Yes’ button.

Depicting "Delete RAID sets" icon selected in "Disk Utility" window.

4. Once the RAID 5 set is deleted, you will need to create a RAID 0 set from the CDU Disk Utility.

Depicting "RAID 0" icon selected in "Disk Utility" window.

5. After the RAID 0 set is created and you can see the drive on your desktop, you can use the CDU to delete this temporary RAID 0 set and re-create a new RAID 5 set.

Depicting "RAID 5" icon selected in "Disk Utility" window.

6. Once RAID 5 is created, go to Apple’s Disk Utility and partition the drive.
