Hey guys I'm having problems backing up my computer. This is the situation. I backup my Windows 7 Ultimate Seagate 3TB hard drive on a 2TB external hard drive by WD. I backup using Norton Security and Windows backup, two seperate backups. I've been doing this with success for 6 Months. Now I can no longer backup using either method. Both give me the option to select my external hard drive, but then both say it doesn't exist. My external hard drive is FAT32 and always has been. This is also important because I move the hard drive from windows, mac, xbox 360, ps3, and other blu ray devices. FAT32 is very compatiable friendly. Last thing of note is I installed a second hard drive, same model as original. The new hard drive is now my primary hard drive to the BIOS/Boot. I have Ubuntu 12.04 64 bit installed and use GRUB to boot into either Windows 7 or Ubuntu. Had to use Ubuntu to allow windows to feel safe and not wipe everything on the hard drives like a mad man. My external hard drive isn't too full and I can access its data on windows 7 BTW. So........ I need to fix my backup, any suggestions?
