Hi: Recently I noticed Sun Solaris used CDs with a UFS File System. So I decided to try UFS and Ext2 on Optical Disks. It should work on CD-RW, but I had spare DVD+RW disks, so I decided to get more ambitious. Note that DVDs use 2048-byte Sectors like CDs, but they're handled in Error-Correcting Blocks of 16. You can't expect DVD-RW to work, because DVD-RW only writes complete ECC Blocks. But DVD+RW (like DVD-RAM) can update individual Sectors. FreeBSD UFS1 wouldn't work this way. The FreeBSD Handbook gives instructions for DVD-RAM, and obviously DVD-RAM has a different layout. But OpenSUSE Linux seems okay with Ext2 on DVD+RW. I copied a large Subtree and checked the result using diff -qr. Does anybody have thoughts about this idea? Like: Any disadvantages which haven't occurred to me? Obviously if you're recording Personal Information on Removable Media it might be preferable to use a format which isn't readable under Windows.
