OTG Volatges or Amps for HDD

hi everyone

I was wondering if anyone knows how to increase the voltages or amps for OTG to make power HDD successfully

I have 1TB and 2TB HDD
both are working with my Note 3 N9005 and Note Edge N915S without extra power

but for my Note Pro P905 they both need external power
the Note Pro does not provide enough power for them

so
I want to know if there are files that need to be edited to increase the power supplied for the HDD through OTG cable or do I need a custom kernel

thanks
