I have used a Maxtor OneTouch backup drive for years, but I'm not sure what I am doing. I have the drive hooked up and when I hit the button, my pc displays an EMC Retrospect Express HD 1.1 window as it always has.
I deleted a bunch of backup files on the MAXTOR to clean it up and I have only left one backup on it. If I click on My Computer, it shows that my C: is 56gb with 28gb free space. And my E: (MAXTOR) is 93.3gb with 84.9gb free space. So lots of room to store backups!
If I click Setup > Comprehensive Backup (Recommended) > Next > choose My entire computer > Select the disc to store your backup(choose Local Disk (E:)) > Next > Select the days (choose any day and time) > Finish, it says Cannot save setup, check the selected drive to make sure there is enough free space > OK. It goes back to the Welcome page and shows that the is 1 restore point available. Automatic Backup is Off.
If I click Back up Now, a Disk is not available, Cannot start the operation because the disk to which files are being copied is not available. OK
If I hover the mouse over the Retrospect Express HD icon in the task bar, it says: Retrospect Express HD will back up all files on my computer...
But if I right click the icon and choose Back up now, a window says Disk is not available. Cannot start the operation because the disk to which files are being copied is not available. Huh?
Same thing if I open it up and click Back up now.
So I can't do any new backups. I need some help! Any ideas or knowledge? I posted this same info on the Dantz Forums site for EMC Retrospect and haven't gotten any responses.

I sure don't know where Retrospect lists that feature.

Some utilities have a checkmark/tick in their Options or Properties to allow:

Place icon in Notification area.
or
Place icon in Taskbar.
