When I have written or erased a CD RW with Toast 5.something on the MAC. I cannot add anything or erase or do anything else with that damn CD execpt reading it --- because every program tells me that my CD is WRITE PROTECTED (WinOnCD 5.7, 5.0 or CloneCD.

i don't know macs, but i know cdrws, and i must tell u that writing and ereasing are two different things
if u want to write on it, u must make sure it has been at least quickly formatted (clonecd can do that).
once u have formatted it, it should be seen as a normal blank from every burning prog.
hope i made things clear..

Please guy and gals I know how to handle CD RWs. That's not so hard to understand thta they have to erased before you can write on them once again. So, please, no kindergarden replies. I have a serious and I need at least someone who has read "Write Protection" in this context.

In oder to tell you once again: The RW is erased fully by the MAC and no PC-Prgram I use (WinOnCD 3.7, 5 and Clone CD) is able to write on it nor able to erase or to quick erase the CD -- and don't tell me it's a WORM: I can erase and write and add as much as I like on the MAC. The CD-RW fits also in speed scheme of the writer.
