Can files be resaved/copied to a cd-rw disc without having to erase the disc? I want to make weekley updates on some of the file on the disk but not all of them. Each time I attempt to re-write to the disc I am prompted that this is a read only file/disk. firstname.lastname@example.org
you need a packet writing software (directcd etc.) to do what you want. the software will format your cdrw and treat it like a big floppy. there are several limitations to the packet writing apps (overhead, compatabiltiy etc.) that makes it less than useful.
you can create multi-sessions cdr that will allow you to do full backup of your data instead of an update. like jakerson stated, with the price of cdr/dvr as cheap as they are, cdrw is pretty much ignored. there are also issues with the durability of cdrw dyes that make them a poor choice for long term backup.
CD-RW can still be ok for rotating back-up, provided the data set is not too large. I've switched from CD-RW to DVD+RW for this purpose, but the principle is still the same.
Yeah, dont use RW for archiving, but for rotating backups it's still a good option.
Forget about packet writing software it's not worththe effort in my opinion. I just write multisession discs and when the data is old (that is a newer backup disc has been made) then you erase the old media and re-use. That's what a "rotating backup" implies!
BTW Arrowstar, what burning software are you using? You need to tell us this if you want any specific infomation on how to write multisession discs.
