Two reasons: 1) You would probably have to somehow format the medium before using it. As far as I know, the only mechanism used with CD-RW for random-access defect management is something called "Mount Ranier". I don't really know much about it, but some modern CD writers are advertised as supporting Mount Ranier. This implies that most CD writers don't. I would also expect that it requires special device driver support. 2) The CD-RW medium can only be rewritten a limited number of times, something on the order of a thousand times or perhaps much less. There are probably some well trampled blocks in a UFS file system that would wear out very quickly. Dan Strick strick@covad.net
