How can I use a USB CD/DVD Drive with VA Adjust?
As when I plug mine in and boot up VA Adjust it fails to launch.

Firstly check you have the latest drivers for the device. If that doesn't help then I'm afriad that the device doesn't conform to the SPTI standard.
So you have two choices.
You can download the Nero ASPI drivers, place them in the same folder as VRPC and the edit the Models/Arm 7 RISC OS Adjust(Jit)/Model.cfg file to alter the CD ROM settings as follows:
CDRom = 0
MultiThread = 1
ReadSectorHack = 1
UseASPI = 1
UseSPTI = 0
Basically swapping the values of UseASPI and UseSPTI. Save the config file and see if the drive then behaves.
If it doesn't move the AtapiCD plugin out of the VirtualAcorn plugins folder. This will at least allow VRPC to start up with the drive connected. You can now make a HostFS mount that point to the drive letter of the CD drive:
For example assuming the Drive was Drive D, the mount would be
D:\. (Note the trailing full stop)
The mount name should be CDROM.
However using this method you won't be able to read RISC OS format CDs.
If you still need to do this and have a "real" RISC OS machine, or a VRPC on a machine with a normal CD/DVD drive and can network this with the laptop you can share the CD rom drive over Acorn Access.
