I have found CDRW to be unreliable and have lost data even after just one year. With blank CD's so cheap (I buy silver blanks for less than 20 cents each in bulk) I just Burn everything to CD as soon as I have a diskload. Then I use a utility for atuomatically cataloging my CDS in a database format so that I can instantly find any item. I probably have 500 CDs of data archived and have never lost anything. And it never takes more than a couple of minutes to find anything. Forget CDRW - save up for DVD-R
