I have exact same problem, Using Windows 7 and Xp on the same macahine. I've been working on it for 2 days now and can't find a solution and so far have'nt came accross anyone in any forum who has encounterd this. The weird thing about this one is that Windows 7 backup rejects my backup device but reconises my hard disk, yet disk manager does the opossite. I suspect the conflict may be that to run xp on Windows 7 drive you have to set your hdd in bios to compatabillity mode, and also that to run 2 OS's on one disk can cause a drive letter conflict if sharing files between both OS's from a third partition. If i get to the bottom of it I'll let you know or if you have found a workaround or anyone else can help please put me out of my misery.

oh btw if your desprate to back up your machine as i am, you can use the XP backup console as an emergancy messure, you are backing up the fault aswell but maybe there will be a fix in the near future.

Welcome wd5fdl,

This thread is about 6 months old, so for your problem we need as much info as you can provide to us. Tell us about your hardware. How many drives do you have? are they IDE or SATA ? How about a screen snip of Device manager, any Yellow Exclaimation marks ?
