Hmm, Cameron, do you only use it for backup, or do you allow regular filesystem use of the drive? I'm wondering because I imagine any use of RAM drive devices (CD or DVD - I have both - but don't use the RAM side of the 2 DVD drives I have) as standard filesystems would mean the discs would be throw away material VERY quickly unless you used a UDF filesystem - otherwise the high hit blocks (directories and filesystem specific blocks) would exceed the 1400 rewrites (or whatever the limit is on your media) VERY quickly? e.g you copy 30 files to a directory - you *can* update the directory block 30 times I would expect you have considered this - but could you give us a run down of your decision to use ext2? Is there a UDF filesystem that you can just put in fstab? (I am assuming that UDF was designed well - I have never looked into it) > | 3.
