plug drive 1 mac , mounted automatically.
in osx re-partition drive , reformat exfat.

plug drive 1 in rpi2 , sda connect/disconnect loop.

ok maybe wrong drive 1.
try drive 2. re-flash sd card , repeat steps 1-5.
, connect/disconnect loop new drive.


lost. thing have not tried using 2nd sd card distro, working on now.

experience similar?

it may usb power issue, need quality psu 5v2a, if psu seperate usb cable ensure quality cable.

add config.txt following

code: select all

max_usb_current=1
