I'm attempting to recover some files with Photorec from a USB hard drive (to another), and since I didn't want to leave my laptop on just for this, I plugged it in to my Pi 3.
I have the official Raspberry power adapter (2A), a Pi 3 and a 2'5 hard drive from an old laptop. Plugged it in, booted the Pi and plugged in the other 2'5 hard drive and the Pi couldn't power both, they kept going on and off. Tried with the "max_usb_current=1" setting, same thing.
Thinking it would consume less power, I un-dusted my old Pi 1 B, connected to the same PSU, and the disks are powered fine here. However the thing here is that Pi 1 B actually seems to be more power hungry than the Pi 3 (source: http://raspi.tv/2016/how-much-power-doe ... ed-to-pi2b)
So my question is, am I doing something wrong? Is my Pi 3 somehow broken? (it isn't even half a year old and didn't even went through heavy usage like my Pi 1 did).
Between the two Pi's, the PSU and SD card were the same. Both always connected to ethernet.
