All PlexWriters can read and write RAW, and Subchannel data just fine. Some software does not correctly follow the MMC standards for doing so. In particular CloneCD has problems with some of the PlexWriter CDRW drives.
I invite you to read the FAQ at http://www.blindwrite.com/faq.htm
In particular read the part describing the problem with SafeDisc 1 and SafeDisc 2, perhaps this will give you a better idea of the issues.
