Basically i want to mirror my drive onto an old backup drive so that if this drive drops dead, i just plug the other one in. Im running xp pro, sp2 and norton ghost 9. My primary drive is 80gb with a 68gb partition and a 12gb. My backup drive is a 28gb. I have 25gb of data on the drive i want to back up, me 28gb drive is empty and quite obviously has more then enough space on it to back up 25gb of data, unless my maths is suddenly bad and 25 no longer fits into 28. I am selecting the drive copy since i want a working backup copy, not an image. So why the hell is ghost telling me there is not enough space on the destination drive to back up the data?!?!?!?!?! I select the destination drive, click next and get the most rediculous unhelpful error box saying "Unable to update settings. The selected destination is too small to hold the data. The parameter is incorrect". WHAT THE HELL? things like this really piss me off. Theres CLEARLY more than enough space for 25gb of data on an empty 28gb drive. I previously tried acronis trueimage 8 only to be told the same thing. now either im imssing something or these programs are too damn stupid to do very very basic maths. I have tribple checked how much data is on this drive and there IS only 26560mb used, the destination has 28105mb free, and this is according to ghost itself, as well as windows explorer.
