CDA can be forced to see this IDE drive, but it only writes at 16X, which on my machine(500 mhz Celeron) causes buffer under runs. However, Collin Hills CDPBurn 1.13 at projecteva.net will burn at 16X if Burn-Proof is enabled. Vegas Video 3.0 can only burn at 6X on this drive. I am very gratefull to Collin Hill for enabling me to continue to use CD Architect. Trying to get Vegas 3.0 and the Plextor to work together has been a frustrating and time consuming experience. Tech support tells me that Sonic Foundry is working on a fix. Untill then, I'm sticking with CDPBurn 1.13 and CDA.
