is the writer sony crx-100e supported by clonecd .. or am i just to dull to copy the encarta 2000 cds?
The Sony CRX100 is not completely supported (http://www.elby.de/CloneCD/english/cdr_s.htm#SONY). It can only back-up the normal SafeDisc protection in SAO-RAW and that's is. If you're lucky the Encarta disc have this (rather old) protection and it can make a back-up.
For the rest it's not compatible (can't write in DAO-RAW96).
Ps. For an explanation on RAW check the CD Freaks Knowledge Base here: http://knowhow.cdfreaks.com/article.php?ID=118
