Didn't know that, but good info.

Hadn't thought of that, good idea.  So I'd keep drive 2 as ext2 and do a
new install on drive 1 with ext3, then put data on drive 1 and redo
drive 2 under ext3.  Sounds like a good plan.  It also means I don't
have to have the CDRW to do this, but it would be nice.

Yep, just doing backup of data from 1st HD. Will be pursuing dump and a
cron job beginning next year to auto the backup.
