Anthony;

Hmmm.  Boy, I'm sure sorry about that (data loss).  I reviewed my 2  
cents posted on Dec. 30, 2010 to be sure the "back up up your home  
directory in its entirety (rsync, tar, etc.)" was suggested.

Looking to the future: since we've been speaking of disk cloning here  
on NMLUG, that's a great way to ensure one has an entire backup of a  
system before reinstall (if one has two drives of equal capacity or  a  
second destination drive to copy to of greater capacity).

Another good trick for the future is to use RAID-1 (two drives,  
synced) and then add, sync and remove a third RAID-1 member before  
doing the reinstall  There are means of converting single drive  
installs to RAID-1.
