Hi. I tryed to make a system back up but it keeps failing with error code0x80070002) (windows cant find a backup devise) went into disk manager and found that my external hard drive that I had plugged in to make the backup on was present and working fine, the strange thing was that i couldnt see my internal hard drive, I did the command promt "devmgr_show_nonpresent_devices=1" this enabled me to see the disk in devise maneger but windows was telling me that the disk was not connected to the system? system restore wont work and like a fool i deleated my previous backup image to make room for the new one. I also tryed startup repair and this failed to find any errors, I should point out though that windows explorer shows my internal hard drive, which is the drive my OS is running from but disk manager refuses to show it and i dont get a "show hidden devices" in the view tab either. I also have XP installed on a different partition to run some old stuff i like to use and the disk manager in xp is also hiding my hard drive. any ideas??​

How much space do you have and have free on the back up partition?
Did it ever work?

Heres my configoration: I split my hdd into 3 partitions, Drive letters C,D and F. Installed xp on (D) win 7 on (C) and installed all my software on (F) from both OS's as to use less space so in essance both OS's were sharing the same program files folder. Do you think that maybe this has caused the conflict?
 

My Computer

Any changes could cause a conflict, depending how it was done. Check the hard drive, as above. What the link says is go to website of the HD mfg and get the test.
