I have been using NG15 for over a year successfully w/o issue. I backup my entire computer daily to a 3Tb Western Digital hard drive. Been using E:MyBook. Suddenly NG15 successfully saves but WD hard drive is 'unavailable'. Hard drive is healthy.
Reassigned via Windows XP to G drive. Backups still fail to be saved.
This must have a simple solution. Anyone have a suggestion?
