ok guys this is driving me nuts. I have my desktop as my main pc for my home-group.. i have my 1.5tb external connected to that as well as a internal 1.5tb. now i have both drives set for advanced sharing everyone read right for my home group. i see them perfectly fine and can transfer data too them pics apps. no issues even music. but issue is when i try to run a backup from my laptop to this location for my one drive first off when setting up backup ask for credentials. i have no password on my homegroup. so i use my pc name and my pc password for my laptop, i start the back up always goes to 57% then fails with Error Code 0x80070005 - Access is Denied. wtf am i doing wrong lol. i can access everything on them under network drives in my computer. i don't get it. I really dont wanna have to set up my network passworded at home cause of fear my xbox 360 wont work right. i do alot of media sharing to it. can someone point me in the right direction here what i need to do to get backup working correctly? I dont know if it matters but i also back up my pc to this drive. but theres still over 800gb free.
