cp -a /hda1/* /hdc1

ext2

Is there something more suitable for copying 500-1000MB of files?  I tried 
dd between identical drives, with bs=64k or larger.

I spend time in three places, have 2-3 computers with the same software at 
each place, and keep anything I need to access online at a shell account 
where I do not have root privileges.

The computers are all free because our friends need newer ones for 
Windows.  We are setting up linux/Opera for other friends on 500MB drives, 
when their 20GB XP drive dies.  I will set them up as user for added 
security.

I have never heard of gvim before.  I compiled busybox vi but have not 
learned to use it.  I use pico in console mode and am trying to learn to 
write simple rtf, maybe by changing the keycodes for the function keys so 
F1 is bold-on and F2 is bold-off, etc., to avoid needing X at all.  I 
could not find a console wordprocessor for linux, and wordperfect and VDE 
don't work correctly in dosemu or qemu.

If I do have to use Opera, does it matter whether I load X and dial as 
root or user before using Opera as user?

Thanks to all of you for the helpful ideas.
