USB 3.0 drive keeps disconnecting and reconnecting when i move files

ok so im sure you have seen this all before, its a common issue, but a long time ago i have fixed this issue but i forgot how. i have already tried all the fixes i could find on the internet . i disabled "Allow the computer to turn off this device to save power" on every port, i also went to power settings and disabled use selective suspend setting on EVERY POWER PROFILE.
and i also updated the usb 3.0 extensible drivers and the intel series 8 intel chipset drivers. but everytime i plug my external HDD to my new laptop the first 3.0 port sometimes just keep connecting and disconnecting instantly, and on the second port it connects and stay connected but if i move a big file it will start flickering on and off ( small files i can move) and yes i know about the radiation that 3.0 devices output and i have moved the drive away from the laptop. last step is to disable wifi and try again.didnt work
ps, usb 2.0 ports work fine
