We can read\execute CD's. However if they are blank, we get this error:
"Windows can't read the disc in the drive. Make sure that the disc uses a format that Windows recognizes. If the disk is unformatted, you need to format it before using it."
I contacted VMWare they pointed me to this KB.
USB Redirected CD/DVD burners fail to function as expected (2149632) | VMware KB
Pretty much saying, if you use Horizon 6 or 7. You can not write to blank CD's. The VMware Engineers said they have never seen it work on Horizon 7. Is that the case. This a show stopper for VMware in our environment.
