3.5" HDD not getting power

Bjartskular

I have a 6A 5V psu.
I'm trying to connect a 3.5" HDD to my UP squared, but the HDD does not seem get power when using the 2 pin jst connector.
I have two UP squared, the pentium 08/128 model, but neither of them seem to power the HDD.

If the HDD is powered, though I can't head any sounds from it, then I still have the problem that it doesn't get detected on either board.

3.5"disks are 12V.
The 2 pin power connector is 5V only so you can only power 2.5" disks
