when I try a new backup with my Win 7 Home premium 64bit OS I do the following steps:
1) USB plug-in of external hard disc
2) Call up of Control Panel / System and Security / Backup and Restore
3) In the Backup and Restore window Click the button "Options"
4)Then in the appearing little display choose --> "Change backup settings"
5) And give administrator confirmation.
The search process then is running for several seconds, After that appears a new window "Set up Backup" which shows (instead of the expected external hard drive) only my DVD RW drive as possible location for the backup. When I click "Refresh" in that window the last consequence is that after a short search appears the knockdown announcement:
"The parameter is incorrect. (0x80070057)".
Nothing else happens. What can I do?
I'm really thankful for your help
