external hard drive? - Nexus 7 Q&A, Help & Troubleshooting

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?

yes could u test it out? i was thinking of buying a portable hard drive but not sure if it will have enough power to use it
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.

[INFO] USB host works with female to female USB gender changer

I bought a USB female to female adapter to plug on the end of the charging cord, some things work, some things don't.
List of devices that work:
HTC Hero - Mass Storage mode (works 2 out of 5 tries aprox.)
Logitech G9 - Works, although only default buttons (left, right, scroll, middle) seem to work
SanDisk Cruzer 4GB USB Stick - Works
Generic Logitech wired keyboard - Works, although not all keys do.
List of devices that DON'T work:
Logitech Wireless Keyboard K250
USB external DAC
Generic Logitech USB mouse
I hope it can read usb flash drive too !!! already bought my female-to-female adapter too
I just tried hooking up my HTC hero with mass storage enabled and it seems to be hit and miss? It recognizes it 2 out of 5 times or so.
How about finding and wiring USB from the 40 pin connector
It is a given the 40 pin connector has USB. Does anyone have pinout / mating connector info?

Don't have any on hand at the moment, I will possibly have access to an ext HDD tomorrow though and will check it then if I can.
That's great news. I did like having USB host on my GTab.

NTFS SHOULD be supported, but yes mine are all FAT32/FATex/ext4
i will have to try again, i built a gender changer, tried it with one mouse, and it did not work so i assumed it would not work for anything, i'll have to try some thumb drives or something.

it seems really picky, it recognized my G9 mouse but not a generic logitech one.
Just speculating, but I would guess that it isn't up to spec. So devices that have looser requirements will work (say it can take 4V instead of requiring 5V), but devices with stricter requirements fail.
did you try a all-in-one type card reader?
or connect digital camera to it?

No, Usb mouse is supported by HC. You can use one with the dock. This is more likely a power thing. The port's main use is power in and data, not power out. It may have strange limits.

Picked up a USB female to female plug today, and proceeded to plug in various drives, mice, Phoness etc, but no sign of anything happening at all. Is there something else I'm missing here? Cheers.
Can anyone with an SD/card reader see if it's recognized?
I'm going on vacation soon and would love to back up my photos to the TF.
Thought about this 2 days ago and bought one yesterday. Tried to plug in my Inspire 4G, external USB HDD and USB jumpdrive. None of them worked.

I tried a multi card reader and it didn't work. I didn't try a card reader that reads only SD (don't have one) but I doubt that it's gonna work given everything else I tried didn't (usb mouse, usb flash drives, Nikon DSLR)

Galaxy S2 USB OTG

Ok, in theory Galaxy S 2 supports USB On-The-Go which means, it can be a USB host device for things like pendrives, digital cameras etc.
Granted of course, that you have the necessary cable.
Has anyone tried this feature?
Also, does the connected device have to be formatted as fat32?

FYI, mouse and keyboard are bluetooth.
I agree with the reviewer, big black mark on Samsung for not including the required cables with the phone for USB and HDMI.
at about minut 4 he says that usb mouse and keyboard doesn't work.
this is really a bad news for me

I am also afraid so When my phone arrives, I'll test it with ntfs & ext3.
Update on USB Mouse - some are working. Check my thread in the accessories forum for more details.
Hi there,
Got my £2 cable from Hong Kong (ebay purchase today).
Works great - even runs my 500GB HDD (this has to be plugged in to operate anyway - not sure USB powered HDDs will work).
If anyone's interested, the item description was:
Micro USB Host Cable for Nokia N810 OTG on the go N 810
No mention of the SGS2 - but I can verify that these work just fine!!!
Jamie
Any Nokia compatible OTG cable seem to work. I've successfully tested several different cables (all from eBay) with usb sticks, optical mouse and usb based memory card reader. However, usb based wifi sticks, fast ethernet dongle and tv-card didn't work. We probably need some new drivers and possibly more power (an usb hub could fix this).
I bought the Nokia USB OTG adapter too. With FAT32 Sticks ists working. But without NTFS support it is nearly useless for me.
umm...i have a nokia n8 and i took off the OTG cable that came with it before selling it in favor of buying a new Galaxy S 2.
However, the nokia OTG cable is perfectly rectangular, whereas the Galaxy S 2 cable connector is a bit "broken off" two edges, hence, using them is impossible together...but i managed to get them to work (in the shop where i tried the Galaxy S 2 at least, i didn't buy the phone yet).
I used a rasp, and filed off the edges of the Nokia OTG cable carefully to match the "broken edges" as the Galaxy S2's connector shape...took that cable to the shop where there is a working Galaxy S 2 unit, and connected it with a flash disk on the other side aaaaaaaaaaaaaaaaaaand......it worked !
If you have the caution and a rasp, i think Nokia's OTG cable should work too..they're cheap off ebay too, aren't they ?
Just ordered one of those off ebay (The Nokia N8 compatible one). Would receive it by tomorrow. I hope it works!
Here is mine ****ty review of USB mouse, USB keyboard and USB lamp.
http://www.youtube.com/watch?v=xQn1DCA0PRQ
here's mine, got it also from ebay.
If you can't get it to recognize USB mass storage I would suggest using USB Mass Storage Watcher: https://market.android.com/details?id=com.skidmrk.umswatcherotg. It will let you mount any type of external storage (NTFS, FAT 32/16, EXT, etc... It's free.
Also, this is a good USB host cable: http://www.amazon.com/gp/product/B005GGBYJ4?ie=UTF8&seller=A76FR6O1NBAXV&sn=T & S Electronics, LLC
I seem to get a "Clear USB" error when I plug in certain usb drives. I'm not sure if this is related to the drive being NTFS or if it is above a certain size. I can't for the life of me find any specs on the whole feature, including its maximum output power.
Could anyone shed some light on the subject from their trial and errors?
Thanks,
Alex
It works with a lot, but not all USB devices.
It doesn't read NTFS format.

New USB Adapter! Need help.

I just got the usb adapter and it work fine with a mouse or keyboard. The problem is I didn’t get it for that. I got it to plug in an external usb drive and for that it is useless. I have tried no less than five different usb drives and the tab sees them as a usb drive but I can’t read or write to them. They are all Fat 32 and under 32gb. WHAT AM I DOING WRONG? Or is there something wrong with the adapter?
Thanks.
I'm able to transfer files with no issues at the moment.
I had success by using a file manager app I got from the market, then navigate to /usbStorage/sda

Make sure to be working in sd card usb area because if you look in the regular usb area it does not show up
If the drive is a spinning harddrive you need to use a powered hub. Plug the external drive into the powered hub, then plug the hub into the usb adapter. Then plug the adapter into the tablet. I hope this helps you.

[Q] External HD for NookColor

I'm looking for a...
>very portable external hd
>that has 320GB to 1TB
>that can be connected to the NookColor (which means that it has a micro usb cable or a mini usb to micro usb adapter)
>and can be mounted/navigated using the NookColor's File Manager Apps (Astro/Root Explorer/File Expert/ES File Explorer etc.)
Is it possible or am I dreaming?
You are not dreaming. The requirements are as follows:
Purchase a micro usg to usb(female) adapter. These can be found through amazon, where I got mine) or ebay. About $3.50
Be running cm7 (I am running 7.1 rc1 n144) and have nook tweeks installed.
Find an external hard drive with its own power supply. Usb will not power the drive through the nook.
I run flash drives and sd cards through a powered hub and have connected an old passport external hard drive (the ones with the external power supply) and a maxtor hard drive (I believe they called them book drives) which had an external power source.
Dal, Verygreen, and the rest of the excellent devs here have taken a little e reader and developed a 7" tablet that can rival almost any tab on the market at this time. Buy your adapter, a powered usb hub, and start playing with the usb host mode in nook tweeks. You're gonna love it.

Good luck with the webcam. I have tried 2 cams; a logitech quick cam pro and a MI el chepo cam. Checking dmesg, both cams were recognized and assigned an IRQ but the software does not know what to do with them. I have tried ooVoo, tango, skipe, and yahoo messenger video plugin. The cam is not recognized by any of the programs. So far, that is the only issue I have had with host mode. Hopefully, the devs will come up with a way to get cams to work but, for now, I am content. I can connect my Nikon camera to the nook and dump my pictures directly to the gallery for review and editing or copy them to a flash drive for storage. There are new uses for this nook every day.

I don't think the Nook will power an external hard drive via the USB port, so you'll lose a lot of the portability you're looking for by having to drag around an external power supply.

Do you think you can recommend one or at least link me into a site that has one? Preferrably a 1TB, and is very portable (small). I'm trying to do my own research but it's hard to find an external HD that requires external power supply. All of the HD's I've seen so far is getting it's power from the USB itself...

that second picture looks like it has some different components from the first. I really like that setup far better than the first picture, could you either post or PM me all of its components?
I believe using a powered hub with any hard drive will work. Also I have a USB hub with a micro usb input, that could be used with a mini-b to micro-b cable. I think that would cut down the clutter.
Here are a few of the components I have been using for usb host mode. As previously posted, yes, a powered hub should work with one of the new compact hard drives.

[Q] Mount HDD without power source?

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.

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).
