Too unreliable. Instead I save to the hard disk, then use CDBURNERXP to erase my temp CDRW media and then record my working set of documents and software (currently writing software.)

However with 1GB USB memory keys now under 20 bucks I have stopped doing even that. I still save to the hard disk and then send a copy to the memory key.

WHY!!!!??? Because this way I have multiple copies of my work and can even recover if the memory key/media gets lost or malfunctions.
