I used a partition manager to create 2 partitions per HDD. Now trying to use your Drive Backup Program. On HDD I have 2 identical partitions, I use Disk 0 to give me OS partition of C: I have a similar partition on Disk 2 to give me D: ‘OS back up’ D: partition is empty, (see attached screen shot) http://s771.photobucket.com/albums/xx351/Tafflad/?action=view¤t=diskpartions.jpg What I want to do is take a partition back up of C: and put it in D: ... giving me a back up OS in case of future problems ...a typical scenario for the program I think. With D: empty there is loads of spare capacity ........... however when I click on the ‘partition back up ‘ button on your program, it initiates but throws up error : “Wizard did not find unallocated space where a new copy can be created ....” Do I need to delete the D: partition to allow back up ? ..... your help appreciated.
