[Q] Mount HDD without power source? - Nexus 7 Q&A, Help & Troubleshooting

Hi,
Is it possible to mount an 2.5" HDD without an external power source?
I would like to buy an Western Digital HD Elements SE 1TB 2.5 USB 3.0 but I do not know whether it is working with my Nexus 7 or not...
A usb stick (with an usb OTG) is working but a real hdd needs a lot more power.
And a self powered hdd (with wifi) is not an solution for me.
Thanks in advance!

It depends. I had to splice 5 volts of power into the usb cable of my older usb 2.0 ext hdd to get it to spin up and mount, but some others I know say they dont need ext power on their newer usb 3.0 ext hdds. But, I dont know if it is all usb 3.0 drives.

Let's say, I buy a 2.5" hdd without external power source but I have no luck and it can't be mounted (not enough power). Is it possible to somehow plugin an external power source, so the hdd can spin up and mount?

That means, a usb OTG is wokring fine with usb 3.0? Usb 3.0 is compatible with usb 2.0, but I was a bit concerned that the usb 3.0 to usb 2.0 to micro usb 2.0 combination may cause problems.

I know I'm reviving a thread a bit here, but I have a WD Elements USB3 1TB drive and an OTG cable.
When I first got the drive and cable, it all mounted and worked great. It wasn't until I hooked it up to a PC for the first time to transfer stuff to it that I started getting issues.
Now, I can use it with the PC no worries, but it won't mount on my N7. It'll sometimes flash up that there's something, but then nothing. Is the format wrong? Should I go with making it ext4 rather than NTFS?
Been hunting for more info on it, and will continue to do so, just hoping that someone else has come across this and has a fix or some idea on what's going on.
Thanks

My guess: The Nexus 7 has not enough power to spin up and mount the drive. You have to use an powered hub (e.g. Y-cable with external power source).

external hard drive?

Hi people,
I read in a review that you can connect an external hard drive to the nexus 7 (the usb powered ones) via a USB Host Cable.
Could any of you tell me if this is correct or not? As i have an Archos 80 g9 and i know it cant do it off the micro usb only the USB 2.0 slot it has.
Thanks a lot for the help

Yes, it is possible but you may need to provide external power to the drive. Use a powered usb hub or something like that. The Nexus 7 most likely won't be able to output enough current to power a spinning drive.
Ah ok, so you are saying that you plug the usb host connection from the nexus to the usb hub and plug the hard drive in to another port on the hub?
I just want to know if this works as 16GB isnt much space when you want to take it on a trap to watch films.
cheers
you need to be rooted. my understanding is flash drives or micro sdcards are good to go, not sure an external hd will work unless powered as previous poster alluded

Since N7's have been out for a few days, has anyone tried hooking up a portable hdd using a micro otg cable? I could plug my portable Toshiba hdd into my Acer A500 tablet without rooting and it would read the contents of the drive just fine. I would watch movies and view pictures as if it were an sd card. Wondered if the N7 unrooted could do the same?

No it does not mount the external storage nor does it have an option to do so. You need to root and install chainfire's stickmount app for this to work.

Hi. I decided to use a wireless drive to store all of my music, movies and documents. So, I purchased the Seagate GoFlex Satellite Mobile Wireless Storage. You can use with Android or IOS devices. I love it.
Yes, its a no-go out-of-the box connecting to a USB thumb drive or a powered HD with a microUSB OTG cable. This doesn't really surprise me, though, because they would need to dynamically detect the device type and mount it on the system. What I haven't tried is a USB keyboard. Anybody do that?

does usb 3.0 work? or do i need to buy a usb 2.0
I've tested mine with an old 60GB WD Passport and a new 500GB Freecom XXS. Both are 2.5" USB powered external HDDs, and both worked fine.

great thanks for the info. btw is the new one using usb 3.0 or 2.0? do u know if usb 3.0 will work?
I just plugged in a full-sized USB keyboard using my OTG cable and it works fine. I can touch type, use the cursor keys including ctrl+arrows to skip words, bring up menus with the context menu key just to the left of the right-hand ctrl key, etc, etc. I'm sure it must be using up my battery at a faster rate, though.
Edit: It's just occurred to me that there's a problem with using a USB keyboard to type when the N7 is in portrait mode: finding a stand to hold the tablet upright at the right angle when the USB-OTG cable is sticking out of the USB port at the bottom of the tablet.
Mind you, it's great being able to type at full speed without a soft keyboard hiding a large chunk of the screen.

You can get OTG cables with a right angled micro-USB plug on them, which might help your stand problem. I have one on its way as I was concerned about knocking/bending/snapping the straight plug when its sat on my lap in portrait mode.

Or, just turn the tablet upside down so the cable is pointing up. The display will rotate appropriately.
I think but not sure that you'll want cm10 for the rotate from any angle thing...

how did you manage it ??did you use nexus media importer
Without a custom kernel, the external hdd won't work with Stickmount or NMI if it is formatted NTFS. I haven't actually used NMI, but others have posted about the NTFS issue.

Asus Vivo Smart ME400 micro-USB port

Does the Asus Vivo Smart ME400 micro-USB port support USB devices like flash drive - keyboard - mouse - HD & CD drive? If yes, where do I get the right USB adapter for it? THANKS.

Use a regular OTG Micro USB to USB adapter
I've been testing my micro USB port with a micro USB to USB OTG cable I have.
Logitech G700 mouse works.
Kingston micro SD to USB adapter works.
Corsair Vengeance 2000 headphones works.
WD 500GB USB 3.0 hard drive works.
Samsung Ultraslim DVD drive does NOT work.
The Samsung DVD drive did work on the full sized USB port on my Samsung 500T tablet. But on the ME400, the light lights up once when I plug it in, but never installs the device and doesn't have any power afterwards. This is a USB powered DVD drive.
Surprised the external hard drive did work when the DVD drive failed. But it showed up fine, had some videos on it, was able to play videos from there okay.
I have another external DVD drive that is powered externally, I imagine that'll probably work fine, I'm too lazy to find it and plug it in (it's an old giant clunky beast).

I think the port only puts out 500ma. The DVD Drive is most likely over that. However quite a lot of modern 2.5" HDDs (your external hdd) are just below 500ma in power which is why it works.
I'll try with my Aluratek dvd writer later. It has a Y cable so may need more than 500mA.

My Samsung DVD drive is powered from a single USB cable (no y splitter for extra power). So I'm guessing the micro USB port isn't even outputting 500mA. It worked fine on the Samsung Atom tablet and I doubt that USB port was outputting more than 500mA.
Guys i have this tablet for about 3 years now and now i face a problem, the tab do not charge anymore and does nothing, not even the orange light of low battery, he does give light of charging, but no life, is this a battery problem? Even if battery is dead shouldnt give life with the charging cable and turn on?

How do I power an external HDD so that I can use OTG?

Hey guys!
I have a Transcend StoreJet 500gb external HDD that I want to connect to my Nexus 7 (2012). Flash based usb sticks work fine, but this hard disk with the actual spinning platter doesn't. I found out that you need to "power the hard drive with a usb hub".
I don't have a usb hub, so I thought of this. Since my External HDD has a usb cable with two usb connectors, can I plug one of them into the Nexus 7 battery charger and the other one into my nexus 7 with a OTG cable?
Can I power it properly like that?
Or is it dangerous?
If I only connect it to my nexus 7 it makes beeping sounds and doesn't get detected. Not much power output on the Nexus 7....
Please help!
Thanks in advance.
You need a powered USB hub, they aren't that expensive.
Sent from my Nexus 7(2012) that has zero issues.

Yes you can do that, it is not dangerous. I power my external WD Passport HD by plugging one usb connector into the pc for power and the other into the OTG usb cable. My drive won't spin unless supplied with the additional power. I have also tried it by plugging the connector into an a/c adapter instead of the pc usb port, which also worked fine.

Hi all,
I have a similar problem with my N7 attaching a small USB powered HDD to watch HD movies stored on that drive. Thing is, when I attach the HDD on my USB OTG cable, all i hear is a repeated "clack..clack" and nothing happens, the HDD doesn´t start. So the other day I got my Nexus 5 and for fun I tried to use the SAME HDD with the same cable and same adapter on the N5 and it worked flawlessly! Starts up, Stickount mounts it and boom!
Now how can it be that one device can work with the HDD and one not? I´mm guessing it may be related to AC voltage levels, but shouldn´t the Nexus 7 be able to deliver the same or even more power to the HDD than the Nexus 5?I don´t get it....
Thanks,
Kusie

USB OTG Output current

Can anybody test the Note 3 with a USB OTG cable and external hard drives?
If you are rooted and using the app "Stickmount" https://play.google.com/store/apps/details?id=eu.chainfire.stickmount, one should be able to mount a FAT32 partition to their phone.
If you don't want to format your hard drive to FAT32, then using the app "Paragon exFAT, NTFS & HFS+" https://play.google.com/store/apps/details?id=com.paragon.mounter would allow to mount another partition type.
It would be very interesting to find whether the Note 3 can provide enough power to external hard drives (portable hard drives with no included power supply) during the read and write processes.
Even though a USB 2.0 OTG cable is all that is available (to my knowledge), it would still be very useful to have the full 500mA available on the USB 2.0 portion of the Note 3 USB port.
Most smartphones have much less than 500mA on tap for the OTG connections.
I was able to connect a 500 mA (2.5" 5400 RPB SATA) from ADATA hard drive to the Note III!
Really unexpected. Connected the OTG connector first, then connected the drive to the female USB A port on the connector.
On my Note II it would try to spin up, squeal and spin down.

Awesome, good to hear. Have you tried large file writes and reads to and from the drive in order to see if it is able to complete a write operation? If it can handle writing a bunch of data without corruption, then it very well may have full 500mA output capability.
thanks for the report!
I was able to delete a file from a FAT32 formatted drive. No need to install anything extra. Even though there is a 4GB file size limit, FAT32 is unfortunately the only format everything can read without additional software.
Even windows can't read Ext3/4 without additional software - and the software isn't just click and install good to go.

Just wondering if anybody has any more info on the Note 3 output current? I hope it can power a Western Digital My Passport 2TB 3.0 as well as some DACs, such as the Musicstreamer II without providing insufficient power to those devices.
I went into a store and found that it will power a Western Digital 2tb my passport drive. It wouldn't read NTFS, so either root or exFAT may be required.
I confirm works well on my OTG usb 2.0 from S 2

[Q] Note 3 and My passport Ultra 2TB

Ok guys. I've been messing around for some long time using 4.3 rom and my 2tb passport but with no luck reading (or writing from it). I was under impression that phone has to be rooted for reading only NTFS format but....this is fairy tales if you ask me. Recently I upgraded to latest kitekat available and rooted but still no access to my drive. I tried 3 usb sticks (8,16,64) with no problem using FAT format.
I used paragon, stickmount but nothing helped me to work this out. I'm also having second doubt would I have more luck with exFAT format?
Anyone had similar problems connecting 2tb drive to their Note 3? And disk is spinning I'm positive it has enough usb power.
The phone can only support up to 1tb due to power restriction.
The only way that i managed to get a WD 2Tb drive to work with my phone/tablet was to use a powerbank. The phone doesn't give enough power out to start the drive up.
You need :
- 1 powerbank (the bigger the better, as it will also charge your phone/tablet)
- 1 USB Hub + OTG cable (or an USB Hub that can be used as OTG with the phone)
- 1 male-to-male cable
- the phone
- the external HDD
Connect to the USB hub the HDD using the cable suplied with it, connect using the male-to-male cable the powerbank to the USB hub and then connect the USB hub to the phone using the OTG cable (or if you have an OTG cable with USB hub integrated then it's even better).
Now, the powerbank will give power to all devices connected to the USB hub (the HDD and the phone), so it should work OK.
After that you will need to solve the NTFS reading/writing, for that you should be able to use the app you already mentioned.
P.S. when i was playing on the Tab2 with the above configuration, I also had to put an usb stick in the USB hub. For some reason the tablet didn't detect the HDD on the hub unless there was an USB stick too (never understood why). I don't remember having the same problem with the Note3, but i didn't test extensively so your mileage may vary.
Edit : an example of OTG adapter with integrated USB hub for Note 3 : http://www.ebay.com/itm/Micro-USB3-...-TF-Samsung-Galaxy-Note-3-N9000-/171300593212
Thanks for reply verszipo I was looking at this cable, hoping this could power up the drive while phone continues to operate itself without additional power. So Is it possible to have power supplied directly over wall plug instead of power bank?
This USB hub seams like nice idea.
Theoretically connecting like you suggested should work even if I leave disk in NTFS format using tools I mentioned before?

If external hdd is larger than 1 TB,
Use usb "Y" cable to add external power source to connection.
Hey!
I use 1.5TB HDD with mu N3 and it is NTFS...
Why cant you use USB hub with external power supply (try to find out if it is 1A or 2A? bigger = better), and at phone install total commander with plugin USB plugin for Total Commander (no root requided!!)...
I use a 2tb wd passport. No need for external power source. I use paragon to read and write to ntfs partition. My drive gets detected within a few seconds but takes several minutes to mount the drive. Maybe you just need to wait. I know my drive is mounted when the My Files app launches by itself and shows the drive contents.
I received my Y cable hoping extra juice could solve my problems but I have no luck at all. No matter what I use I can't make my drive read. I don't have any options to choose.
Maybe I should format my drive using different allocation size unit, I never formated it and it's not 4 months old. Maybe my phone has some crappy cache leftovers so I should use cleaner? Hell I don't know what to do anymore. Usb sticks are working fine all the way.
Ok update on topic. I mange to make it work. I formated to NTFS with default allocation size, nothing special. Using paragon + total commander plugin + total commander. Works fine now WITHOUT additional power. Only downside is that mobile battery drains way too fast when you connect storage on it. It does not matter if I plug in additional supply to drive or not, draining is the same. Anyone noticed this and any workaround for this.
Thank you guys for suggestions.
I mounted my CN memory usb3.0 3tb drive with paragon in my rooted sm n9005
It mounted fine to a folder in my int SD, and i copied ober 20gb of data
