I have a 1 terabyte Seagate Backup Plus external hard drive. Just had it a month. It started blinking and is not recognized by the laptop. I have another one exactly the same and it works fine. Switched the cables - no change. Drive still blinking. Any way to save this? I just put a lot of music files onto it and was just a about to back etc. Looked through Seagate tutorials etc but don't see much to fix it. Much obliged. T Leve
