i think the original idea was someone trying to determine the best way to transfer files from school to home and back. yes, cd is what shannon originally mentioned, but a cd-r/rw isnt the only way of fulfilling the need she spoke of: > Is there a way that I can burn a single data CD over a period of time > using both a Mac a a PC without having to reformat it every time I > need to burn more data? so others were simply supplying other options that she might not know about. heck, you say not to spend money when it is not necessary, but then offer her option as buying a $100 piece of software...? without toast it is true, this cannot be done (or without another commercial burning application) as the os x burning software only allows 1 burn per cd-r. with toast, tracker is correct, burning iso 9960 format on a cd-r WITHOUT "closing the disc" (but "closing the session") will allow multiple writes between macs and pcs. but i still think what would work better would be a random read/write drive such as flash memory, or your zip disk. (with proper compression, sizing, 100 MB should be a decent size for director projects-all but my final piece were below 100 MB in the classes i took on director/multimedia production) and i would actually use 2 forms of media, just for extra special backup. burn a cd and use zip/flash) it sucks losing 8 weeks worth of work due to corrupted media =( shannon-say hello to the rochester winter for me! i spent four years up there-2 across the street from MCC at rustic village... sandor On Jan 22, 2004, at 3:16 PM, Tracker at aol.com wrote: > I think the original thought here was the idea of burning a CD that > could be > read by both formats, Mac and PC.
