[TriLUG] image of hard drive question

[James Jones]

Hi!

Here is a question from a newbie at hard drive backups. ( ME ) I am
planning to create a mirror image of my windows xp hard drive to place
on a shelf for use if original hard drive dies.

The question -- If original hard drive dies, is there any known
software that will NOT run from the mirrored hard drive? ( assuming
nothing else in original computer has changed )??
