CD-DVD Speed not working on BenQ 1640

I was recently trying to scan some of the media I burned a couple of days back on my reflashed Plextor 740UF–>BenQ 1640. I started up the program and I selected Disc Quality Test however, the CD-DVD Speed would only show the drive spinup and then stop indicating any activity, whatsoever. And I tried the same settings on a different computer with a Sony DRU-710A…no problems. Any suggestions or help would be appreciated.
