Go on ya Kelvin thanks indeed, my desktop Hard Drive is well under 1 terabyte.
It tells me that it is
1.09 TB free of 1.81 TB so do you think the unit you suggested will do the job, or should i make a bit more room for it.
I have only last week backed up the entire computers data, other than software programs that is to a WD external drive so all pictures and general stuff is in a safe place.
If the original hard drive dies today at least i can still put all that stuff back one a new one, however i would rather a cloned copy of the whole lot so i can keep that if the other one gets fried.
Thanks for your help i will get hold of one of those drives you suggested and go for it, got nothing to loose, and if i have problems i will ask you for some expert advice.
