[SCSI - 0] Invalid (Cannot successfully create virtual drives)

Hi there,

As the title says, when I try to create a new drive, it says the drive is invalid, and even if I assign a letter to the drive, it doesn't appear in Computer.

I'm using Daemon Tools Lite 4.47.1.0333, SPTD version 1.83

Running Windows 7 32 bit on a laptop. Please let me know if any further information is needed.
