I have a Sony DRU-500A DVD drive and a Lite-On LTR-40125S and for nearly a month I’ve been trying (to no avail) to get packet writing software to work on both drives. I’ve used DirectCD, InCD, and recently (in frustration), I downloaded Stomp’s RecordNow Max, which includes their version of packet writing software (called DLA). When using Roxio’s DirectCD, it worked fine on the Sony, but it couldn’t format using the Lite-On. Using Nero’s InCD, the opposite occurred (the Lite-On worked, the Sony didn’t). With Stomp’s DLA, the Sony works, but not the Lite-On. Browsing through Stomp’s DLA manual, I noticed a warning stating that DLA can only be used on one writer at a time. It does offer a feature to enable/disable the DLA feature on each drive, as required, but so far I’ve only gotten errors whenever I enable DLA on the Lite-On and try to format a CD-RW disk (hopefully this is just because the Lite-On isn’t supported yet and a PX-engine update will include support in the near future). Anyway, my question is this: Am I correct in assuming that packet writing software can only work on ONE drive in a two reader/writer configuration? Anyone with two RW drives able to format disks on both drives? All replies are appreciated. Sorry about the long winded post.
