On my ole faithful Windows 2000 system, I use TI 9, with 4 USB drives. 2 of the drives are always connected. The other two drives alternate on a 3rd USB port, so I end up using 3 drive letters, but I have a separate script for each drive. On 31 May, I purchased a Vista system, on which I hope to use TI 11. I have 2 USB drives, only 1 of which will be connected at a time, so they would be using the same drive letter. Can I use a single script that would use whatever drive is connected? Or does TI maintain internal structures that would get confused if I did not use a separate script for each drive?
