Nero V9 Disc Speed & Info tool don't see 3rd drive

Win 7 x64
Nero essentials V9
All drives are SATA

I have two optical drives in my tower. InfoTool & DiscSpeed found both.
I added a third drive to benchmark, but neitherr program sees the drive.

The burning program sees and reads the drive with media in it.
Device manager sees the drive.
The O/S sees and can read from the drive.

I have restarted InfoTool & DiscSpeed more than once, but all they can see are the first two drives.

Whats’ wrong?? :confused:
