Wanted to ask those who already have their tablet and dock whether you can plug a USB external HDD (without its own power) into the USB port and use it, or whether external HDD need to have their own power supply? Does the USB port on the dock provide enough power to external HDD?
yes, I've got a 500GB passport and it works great, I stor my movies on it and had no problem playing directly from the hard drive

Thats brilliant news as I have a passport drive as well....just waiting for my dock now.
and it can read and write to ntfs formatted drives. so no 4gb limit.
yep..my western digital portable works perfect on TF.. not sure about those requires additional powers..but it makes sense they should work well too
sweet, i was worried that the dock wouldn't provide enough power to my passport. Man i love those little drives
I've got a simpletech 160GB formatted NTFS and can't find it on the USB port. Any help?
Thanks.
I was able to get my Seagate Freeagent GO drive to work perfectly through the keyboard dock. In fact, I had an SD card, USB mouse and external HD all going at the same time

What would be the difference between a 3.0 usb drive and a 2.0 usb drive? I think the usb ports on the TF are 3.0. TIA - sheureka
interesing.. I can power the drive fine (which is more than I can do from some of the usb ports on my desktop ).
usb 3 seems to have more connections and more power... i noticed that the ps for the tf is 15v vs 5v for standard usb.. I don't know about speed differences though. there are some threads on blown ps's with extension cables too so there is something specific here.
so. i think it's great that the usb here can power a hdd!
Its running usb 2.0
Sent from my Transformer TF101
Need to be careful. Many people are using USB connectors to do things that are very different than spec. Bottom line a physical USB connector may not have USB signals & power on it.
I think it's the drive as it runs fine on my computer, reformatted it NTFS, and even with plugged into both usb ports it still doesn't read in the TF.
USB powers it, tried usb mouse okay, sd card in kb is fine too.
I don't have a problem getting another hdd (maybe one listed here as working).
any other thoughts appreciated.
I am having a similar problem with a WD 500GB and an Oyen esata/USB 2.0 enclosure. Drive works fine on powered USB 2.0 port on my laptop, but not on the Transformer. The drive powers on, the Removable Storage notification flashes, but the drive is not recognized.

Speed and power required. USB 3 is a lot faster.
USB 2.0 ~60MB/sec
USB 3.0 up to 640MB/sec
Prime 1.5 solved the problem. Apparently some custom kernels cannot handle NTFS.
my transformer would freeze if I tried plugging in a drive with multiple partitions, not sure how many partitions it supports formatted the drive to one partition and all is well
I have a Maxtor 3200 Personal storage 500GB with own power supply and it works.
I also have a Seagate 1TB Expansion Portable drive USB2.0 powered and this also works.
Powers up hdd but no recognition
TF101 3.2.1 Build HTK7.US_epad-8.6.5.13 stock
I am having similar issues as Adam. I have a 1TB Buffalo Ministation. My win vista pc also didn't see it initially... had to download the driver. Then I formatted it with a 32GB FAT32 partition and did the rest NTFS. My dvd player couldn't see the NTFS so I tried it to exFAT. Took all night, and still no compatibility (had to try). So now I formatted it back to NTFS. The transformer hasn't been able to recognize it in any formatted format. Not even the FAT32 bit. But it does power it nicely.
Hope someone has a trick up their sleeve, this little hdd is so portable!
SOLVED! I plugged it in on the other side (which is the left side of the dock) and VOILA! I have NTFS and the partitioned FAT32 access. How nice Now to figure out if I can somehow use it without the dock.....
I have a 2.5" 750gb Seagate Momentus HDD and a 2.5" 120gb OCZ Vertex 3 SSD both can be powered just fine by the TF. Using the Vertex 3 drive uses less power than my Seagate Momentus because there are no moving parts so I prefer it.
Incidentally, the TF uses USB 2.0 ports, not 3.0. You can use a USB 3.0 cable as it is backward compatible to 2.0. My Vertex 3 has a USB 3.0 type interface on the external enclosure it's housed in but it kicks back to 2.0 speeds while plugged into the TF which is more than enough while watching movies from it.
Hi people, I need some help
I have a external hard disk 2,5" with USB port, I formatted it in fat 32 for work without paragon NTFS and similar apps
My p3100 with cm10 recognize it perfectly but it doesn't power the hard drive without add an external alimentation like an USB charger for smartphone
It's sad because I always need a wall socket for power up my hard drive
I know there are a lot of 2,5" hard drive that they can required less power than my, but I can't buy another hard disk only for my tablet
So, this is the question:
Can we change the max power output from the galaxy tab or it is hardware limited?
I think about a ssd hard drive but at least 500gb it costs me A LOT! And I need from 640 to 1000 GB
Another method is to buy a portable USB charger but I don't know now how much time it can power my hard disk, I need to do some calculations.
So, what I do? Buy a USB charger or try a method to change the max output from the tablet?

I think a methode like changing output to make harddisk work need a custom kernel and that needs a long wait and may not appear so i think you need to buy the usb charger (cheap) if not working return it
Sent from Galaxy S2 or Galaxy Tab2
Perfect so for the moment I do some calculations and find a USB portable charger that can power my hard disk for about 7/8 hours!
It is a good idea to increase the max power output because if I connect an USB wireless receiver for the mouse and a flash drive tablet stop power out so I think galaxy tab 2 can power out from 50 to 150 mA only
Hello guys ,

Apparently someone have had success with a 128gb HDD... No external power needed...
waiting for a case then will try with my new 128gb SSD...
I am considering buying an Otg pen drive to expand capacity as well as keeping some important wip data off device, but want to know if anybody has tried them in 32 or 64 Gig capacities and how is their form factor as don't want it sticking like sore thumb that could likely damage the USB port. A unit with micro USB on side would likely be better suited, if anyone came across a model that kind?

I am using 3 USB thumg drives. 128 GB and 64GB. SandDisk and Kingston they work with no problems.
Also Meenova MiniMicroSD card reader with 64GB micro SD that works without the OTG dongle.
All work fine.

Thanks,
Do your thumb drives have internal OTG /,MicroUsb (as i don't want to use a dongle cable).
Just Might as well get that Card Reader anyways as that opens up a lot of possibilities.
Thumb drives require dongle.
Meenova goes direct but as for now only 64GB.
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.

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:

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.
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.

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 ?
