Hi All, I have a bit of hard drive cloning to do so I took out my slave and replaced it with a new 2Tb drive today. After a re-boot, I am now getting the non-valid warning. I have looked around here and tried a couple of fixes but can't seem to get it to validate. Could someone please help me out?? Dan077 I got it licked! Thanks to all of this community for all the useful knowledge on this site. Muchly Appreciated!!
