[SlugLUG] Removing an old drive and replicating it's data

[Eric Carter]

Ubuntu (my current OS) is installed on hda (an 180 gig drive)

I have an old debian install that I'd like to keep around for backup
purposes on hdb (a 19 gig drive). It's currently mapped to
/home/ecna/oldhome.

I'd like to (in as little effort as possible) copy all the data over
to hda and be able to find it in the future at /home/ecna/oldhome and
pull hdb out of my machine. Any tips on how to do this painlessly?

I'm not sure what the process would be called, otherwise I'd just google it.

Thanks,
EC
