IOMETER not showing all physical drives

I started to benchmark a new SSD only test SAN at work this week and after running several tests configuered in a RAID setup, I wanted to test the physical raw drives themselves. After deleting the partitions, I could not get the disks to show in IOMETER. The general solution to this is to run IOMETER as administrator under S2K8R2. This did not work for me, as the drives still had some partition reminants from the RAID. The solution: Use diskpart to clean the drives.

1) Open an Administrative CMD prompt- (right click CMD- run as administrator)

2) # diskpart

3) # select disk 1

4) # clean

Repeat until all the disks you want to test are clean. DO NOT CLEAN YOUR OS DISK.

5) # exit

Make sure IOMETER is being ran as administrator and all your disks should now show. Good luck!
