[GLLUG] Establishing Software RAID1

[Robert Youngs, Jr,]

Correct.  Writing a new file system in any instance will erase any data 
present.

Amazon is usually a decent place to get cheap things.  I'm not sure 
about anything locally.  I was recently at MSU Surplus, but I did not 
see any SATA cables.


Cheers,
