OTG Volatges or Amps for HDD

[BuHaneenHHHH]

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

That's odd. It reads my three 2TB WD Elements drives without issue... Even two of them at the same time over a hub works without issue.

Over a hub with external power right?

It works with external power

But try connecting one of them directly without power

It will not work

The hard drives works with My note 3 and note edge without the need for external power

No, just a regular USB hub without external power. This one: http://www.saturn.de/mcs/product/_ISY-IHU-1000-4-Port-Hub,48352,278643.html?langId=-3

But I do believe it depends on the drive itself. I have an Iomega 500Gb drive that won't load without external power, while my 2TB Western Digitals do.

Which variant of the note pro do you have? Is it the P905?
If it is p905, then which rom are you using?

What cable do you use to connect the hub to the tab?

And which models are your 2tb hard drives?
Because i have wd passport 1tb and elements 2tb
Both are not working with tab but working with the phones

P905, P905XXUANC3/P905DBTANC3, pure stock. (Yes, still on KitKat.)

USB Cable is the official Samsung ET-R205UBEG OTG cable.

The two drives are both WD Elements USB 3.0 2TB. Both formatted as EXFAT.

I had a WD Passport once, but it had problems with my old TF700T due to the backup partition and the autorun.

Do you connect any power to the otg?

I did not test it on kitkat because i directly update to lollipop

Nope. No power to be found on a train or in the garden, sadly.

Ah. That could be it.

Buy a portable charger ��


Gonna try to get it back to kitkat and test it

Or see the difference in kitkat kernel vs lollipop kernel

update:

got back to KitKat (P905XXUANC3)
and it does not work without power also and I lost the LTE connection :crying:
flash drives are working fine
only problem is with the 1 tb and 2 tb hard drive
(I don't have a smaller hard drives to test for now)
going back to lollipop and gonna try to find a solution

Bah, I'd really hoped that would work...

I have a portable powerpack, a 15600mAh Asolar Xstorm. It's just not very convenient to have to juggle a 12" tablet, portable harddrive hanging from an OTG cable, as well as a powerpack the size of a 6" phone, alongside my already 5.7" phone, whilst switching trains and standing in crowded carriages. :laugh:

Can you take a video showing that you have a 2tb hard drive connected to your Note pro without external power?

I need to show the technician of Samsung so that they will fix my note pro on the warranty

The only drive I have with me right now is formatted in NTFS. (Because the piece of crap Windows XP Dell PC I have to use here is too old to recognize EXFAT, and FAT32 doesn't support 5GB Photoshop files.) All it does is give an Unsupported file system error. (Which makes sense, as I haven't rooted)

Edit: Okay, borrowing a drive from a friend to check, this is a 1TB WD Elements in EXFAT...

Edit 2: That somehow won't load. Device just says it's blank or unsupported. I'm confused, why isn't this one working?

Can you try with your hard drives and make a video?

I can't make a test because my portable drives are all formatted ext 4 or ntfs, but I'd check the portabla case itself: many portable cases show strange incompatibilities: a different chipset and/or usb chip can be the culprit. Unfortunately the only way to check this is to open the case. WD may have changed something in the hardware or the firmware, if any, over the time and this could explain why some drives work and some not.
My suggestion is to check the compatibility prior to buy a portable drive.

 

[BuHaneenHHHH]

It is not the hard disk itself
the problem is with the note pro
i have many 2tb & 1tb hard drives
all of them work well with my phones
but none work with the note pro

Not the hard disk but its case. It is the combination of case and taget device that makes the difference. Some of my devices do not work if attached to my modem but do work attached to to my laptop or desktop pc, others do the opposite. The only case I found to be compatible with all my devices is a thermaltake one, that I bought because it was listed in the compatibility list of my desktop's motherboard.

hi everyone

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

thanks

my hdd also requires a battery pack to function over otg. its a 500gb usb3 toshiba. i went round and round with this for months and could never solve the problem. mine is the verizon unit, and i think that has something to do with it as any other non-verizon note pro sees the hdd with no problem, no power pack needed. (even works fine with tab pro wifi model and galaxy s4, s5, and s6). didn't matter how i formatted the drive, it still wouldn't see it without the power pack.

quite frustrating.

This will depend mainly from the Hdd that's inside the case.
I personally assemble my portable hdd's buyn a case and a low power hdd (Wd green or so on). It's very simple and you know what you have. Doing this way I never had power problems even with usb2 sokets.
Keep in mind that an usb3 Soket is rated at up to 1 Amp, while an USB2 socket is rated at max 0.5 Amp. I don't believe that any portable 2.5" HD will absorb all that power , but I would not be surprised if on a tablet the available current was much less, to limit the maximum discharge rate of the battery with consequent risks of dangerous overheatings.
In any case I guess that on the Market there are cheap usb gadgets able to measure the absorbed current from an USB socket. Ebay or Aliexpress can be good sources for such gadgets.

I've posted this problem on other thread too but the question is related to this thread too, hence I'll ask.
My smartphone (an Asus device) is able to power up HDD (2tb Seagate Slim BUP) by itself and can read and write files too(I use Total Commander app along with a 3rd party plugin to read and write to NTFS drive.) Problem is my smartphone's battery drops 1% every 1.5 mins when HDD is connected to it directly.

So I want external HDD to draw power from external supply ONLY (from powerbank or 2A charger) and not smartphone. Ofcourse phone will use some power but primarily HDD should use external supply power.
Is it possible to do this ? If yes, which hub or cable should I use ?

I had bought a OTG Y cable but on connecting micro usb end of cable to smartphone, phone started charging itself and HDD turned off. I tried both 5V 2A charger and powerbank with same output.

Is there such thing as a hub or OTG Y cable won't use external power if smartphone is capable supplying required power? Or the cable was faulty? I'm new to all this so could you tell what went wrong ?

i think you should buy a usb hub that can be powered and connect it to the otg cable and connect the power to the hub not to the OTG Y cable

i remember using a Y usb cable like this

i connected the hdd to the tablet using an otg cable and connected the extra usb from the Y cable to my laptop usb port (because it was short and the laptop is closer than the charger )

using this method my hdd worked on my note pro
sadly i do not have the tablet anymore to test it out now
