Mark, I will repeat that I have not looked at Mount Ranier. However, I have used Adaptec DirectCD on a PC. It is less than wonderful. And it is s l o o o w. The PC's clock speed doesn't help much either. It is roughly an hour to format the CDRW disk. Then copying files takes a while. Deleting files also takes a while. I'm not sure about the reclaimed space and how that is re-allocated because frankly it isn't really worth the effort. Perhaps a faster drive would help, and background burning would help, but what is really the point? You mentioned writing and multiple versions. It would seem to me that the reason that you use CD in the first place is to preserve your variations. If you delete them (assuming no other backup) from the CD, they are gone forever. The little writing that I do convinces me that I can never recall the exact style and phrasing when I try to recreate something that was lost because of a crash or software glitch. CDR media is cheap (although MANAGING a CD library is not) and even CDRW media is not that expensive, so why would it be necessary to reclaim a portion of the media instead of having to capability to revert or reclaim portions of an earlier version? If, when the project is complete, you never want to seen it again, just TOSS the CDs. On the speculative side (PURE SPECULATION), I believe that the reason (at least on MacOS 9) that UDF is not fully implemented has to do with the Mac's penchant for maintaining a dialog with mounted devices. I know that with CF cards and FW drives, one MUST 'put away' (aka trash) a volume before ejecting the media OR file and/or disk corruption WILL occur. With a FW hard drive, it is possible to repower the device, but my experience has been that CF cards must be reformatted to be used after this happens. Even CDs (that cannot be corrupted) require this operation. PCs do not (yet) suffer from this data/volume corruption, but even Win2K warns of this (improper unmounting) when removable media (other than CD) is not 'ejected' properly. On method, given background burning, would be to image the RW disk, erase same, and reburn after reconfiguring the image. Granted, it's not like having a large floppy, but it probably wouldn't be much slower. -- SuperMacs is sponsored by <http://lowendmac.com/> and...
