Okay, a few notes in reply to a bunch of different things.

I haven't tried USB OTG Watcher, but Stickmount, at least, is dependent on the kernel for filesystem support and read/write functionality. Not sure why it won't mount EXT based file systems, but I would think that would almost have to be a Stickmount issue/limitation, since the internal storage is EXT4, so the kernel by definition must be supporting it. There is absolutely no reason why this would not be possible that I am aware of, and it's easy to test, too. If you can mount an EXT USB device manually by typing the mount command into the terminal, then Stickmount or similar can do the same thing. In fact, that's all it's doing, scripting the mount command.

Okay, Busybox is a set of tools. Installing it gives you access to those tools. Some programs require those tools. That's 'what it does'. Asking what Busybox does is like asking what the Microsoft Visual C++ Redistributable thing that a bunch of Windows programs installs does. For the user, not a lot. It provides extra commands for other programs to use, a lot of programs rely on it, but most users won't directly make use of it.

And any Busybox apps you see are only installer/uninstaller apps, there is no Busybox GUI that I'm aware of, it's a Linux based, not an Android based program. Many ROMs come with it completely and properly installed, but if you're doing it yourself, you have to both download and run the app before it's there. You can then get rid of the app and it will still be there.

I'm looking at buying a Nexus 7 for my trip to Africa, main purpose to copy photos from my memory cards (CompactFlash) via card reader and putting them onto my external HDD.

My few questions:

* What sort of speeds are achievable with an external HDD?

* Is an external 2.5" HDD able to be powered up by the Nexus 7? Do I need to buy any particular brand of external HDD?

* Can I use a USB hub and connect both cardreader and HDD together, and copy it from one to the other direclty (without using the internal memory of the N7 as cache)?
[Nexus 7 General] Milamber33:
1. Not sure, never measured.

2. It might depend on the drive, but I have a 500GB HP USB3 drive here that I've just checked does work, so it's at least possible.

3. You should be able to, yes, but the chances of doing it with an unpowered hub are somewhat slim. You could try, but I'd be surprised if the Nexus 7 could power both things over USB at once. With powered hubs, on the other hand, I don't think there's any real limit to the number or type of devices you can hook up to it.

mine works fine with the samsung galaxy note OFFICIAL usb otg cable. a cheaper cable from play.com called trixies if my memory serves me right was rubbish an doesnt connect well and needs more force both on the nexus 7 and the samsung galaxy note.

my nexus 7 is unrooted and can copy or stream files from usb stick with nexus media importer app or nexus photo viewer app. since i am unrooted i cant comment on writing to external memory via otg. i can read / stream from flash drive and powered hard drive. havent tried unpowered portable drive yet but will try soon. can read / copy from camera (olymus c 5050) from compact flash card with FAT16 bt cant read xd card with FAT12 format. can read internal memory of my samsung galaxy note on my nexus via usb otg only in usb mode and not in MTP or PTP modes.

but can write or read or stream to external memory wirelessly using the samsung optical smart hub (dvd r/w drive / portable router) along with the smarthub app from the play store.

see demos of these on youtube. see my tagline for link.
[Nexus 7 General] tangcla:

[Nexus 7 General] Jdbye:
I have one and they are rather nice. It works connected to the N7 with a USB-OTG cable too using StickMount, however it probably drains the battery fast since it is both powering the HDD and charging at the same time.
[Nexus 7 General] bubblesmoney:
Yes I could use it too but like i said earlier connection wasn't secure and sometimes would disconnect in the middle of doing something and file gets corrupted. Never happened with the samsung galaxy note official otg cable. People don't need to lose data for saving just a few quid. I was just saying that. If yours works fine then good. Also people don't need to modify cables if they buy the right ones as the right ones fit properly in all my devices

Has anyone got any recommendations on which external USB HDD to use for file storage? I am looking at a 500GB hard drive for travels.
[Nexus 7 General] groovdafied:
Why not opt in for those wifi hard drives from Seagate? I heard it allows internet passthrough and it's 500GB. You connect to the hard drive via wifi...no wires, no fuss. I don't have one (yet), but I'm looking to get one.
[Nexus 7 General] veeman:
You can't connect to it on an airplane though. You have to have wireless completely shut off.
[Nexus 7 General] groovdafied:
Why not just load some content onto your tablet for the flight and keep everything else on the hard drive? How long does your flights usually take?
[Nexus 7 General] tangcla:
Battery life... my primary use for USB-OTG is to transfer photos from SD/CF cards (via cardreader) to external HDD.
[Nexus 7 General] Milamber33:
I haven't done any comparisons, but I have a couple of 2.5" 500GB USB3 drives from HP which work fine, and can be powered by the Nexus 7.
[Nexus 7 General] Ryan35310:
I'd rather do this then mod a Nexus 7 for extra storage.
[Nexus 7 General] rudeguy:
not me

I had 2 phones whose data ports came loose. I don't trust anything dangling from my phone/tablet.
[Nexus 7 General] bubblesmoney:
Then as far as I am aware your only options are WiFi devices like Wii drive or NAS or seagate goflex portable drive or use apps for servers on your phone with microsd slot or portable routers or Samsung optical smarthub, the last one which I recently started a thread about and works fine but it needs power as does not have a battery.

If you are a user who either

a) doesn't always have a solid stable fast wifi connection [someone who travels]

b) installs big apps like MC3, N.O.V.A. 3..

c) loads lots of videos/movies/shows on the device for watching

then there is absolutely NO excuse for buying the 8GB model.

You really are only getting about 6GB with the 8GB model. N.O.V.A. 3 alone is 1.7 GB.

Also there is a terrible downside to consistently using USB OTG: You cannot [as of now] charge the N7 while using OTG, so if you stream a movie off a flash drive, or especially self-powered spinning 2.5 portable hard drive, you will eat up your battery faster than streaming it off the internal storage.

In my mind, I would never even consider buying an 8GB Nexus 7 in a million years. Unless of course, someone was selling it for like $100, NIB on craigslist, in which case I'd resell or gift it to a friend.

If the N7 had a MicroSD slot, things would be drastically different. You can install apps to the sdcard with root/custom roms, but it still is better to run the apps off the native storage. If google had a 32GB model for $300, I probably would have bought it, even though it costs them NOWHERE near the extra $50 for the extra 8GB from the 8GB to 16GB model.
[Nexus 7 General] wizardknight:
One downside I could see, is that you could be forced to choose between wireless internet and wireless HD storage. I know it can probably be setup so you can access the hd from the wireless internet access point, but it is something to keep in mind.
[Nexus 7 General] WinDroidGuy:
Bluetooth tethering works loads better and gives you better battery life...that's what I do with mine, thinking of picking up one of the wireless ones, but I don't see any use for one now. I have tons of cloud storage and always have an internet connection.
[Nexus 7 General] Serial_Noob:
No, you access the internet through the drive. Both the Seagate Satellite and the Kingston Wi Drive have settings to let the drive act as a WiFi repeater.
[Nexus 7 General] WinDroidGuy:
My simple setup :)

Don't mind all my millions of microSD cards, they were all free from previous phones that they came included. I have well over 200GB of storage there and 150GB cloud storage and a few external drives. I don't think I'll ever run out of storage :D lol

[Nexus 7 General] biggiestuff:
I had a question and I couldn't find the answer via search but does the N7 have trouble detecting drives in a usb 3.0 enclosure? I have one but cannot read the drive. I have a SSD drive in it. The drive can be detected if I use a sata to usb adapter though. I'm thinking I need to return this 3.0 enclosure and get a 2.0 one.
[Nexus 7 General] Milamber33:
I can think of 3 possible reasons off the top of my head:

1: The problem might be power. I think the USB3 spec allows for higher power draw from the USB port, which the N7 might not be able to provide.

2: The USB OTG implementation in the N7 might not be entirely compatible with USB3 for some reason.

3: There might be some issue with the enclosure. Have you tested the exact setup you're plugging in to your N7 in a PC?
[Nexus 7 General] biggiestuff:
The enclosure reads just fine on a PC. The power light does light up on the enclosure so there is power going to it but like you said, there might not be enough power. I'll exchange it for a 2.0 enclosure to test it out. It's not too big of a deal but I wanted to know other people's experiences here on the board.
[Nexus 7 General] scandalousk:
Just ordered 2 cables(can't hurt to have a spare one). I made sure before hand to see if it would work on the nexus 7 (which it does) according to other people. I'll get it tomorrow and I'm and I'm going to combine it with a small 750GB usb hdd so I'm all set. I'm really glad that 720p and 1080p films won't be a problem any more. I have to admit, I was kind of bummed that 16gb was the max for a nexus 7, luckily this solves that little inconvenience.
[Nexus 7 General] anthon:
I think that a hard disk will drain the battery very quick, and It might be bad for the tablet to keep it plugged too much time

It is better a flash drive, like a SSD hard disk or MicroSD cards with a reader (I use this option)

[Nexus 7 General] vulcanize:
I got an OTG cable from amazon for 9$ after reading multiple reviews about the ones under a dollar. Paid more perhaps, but no regrets because it is working fine with both my Nexus 7 tablets.

Below is the details about it:

T & S Electronics Micro USB Host Cable (OTG Cable) - Xoom, Galaxy S2, Acer Iconia A510, Toshiba Excite AT305, Google Nexus 7 & more

http://www.amazon.com/gp/product/B005GGBYJ4/ref=oh_details_o04_s00_i00

One thing I need to mention is that the first time I hooked it up to my 2 TB GoFlex external hard drive using "Paragon NTFS & HFS" it worked fine - way better than "StickRoot" app (as for "NTFS mounter" - it never worked at all).

But ever since then the Paragon app has been unable to connect it to the external drive even though I am able to plug and use SD cards and jump drives.

Maybe an issue with the GoFlex perhaps. Still checking it out.

Cheers :)

I'm using this one: http://www.amazon.com/gp/product/B005OOJPKS/ref=oh_details_o00_s00_i00

I bought it because there were reviews saying that it worked with the N7, and it does :)
[Nexus 7 General] Mechanio:
OTG and charging are mutually exclusive by definition (or, at least, as implemented in the N7)... when an OTG cable is plugged in it pulls down USB_ID (the extra 'sense' pin in the micro-USB connector), which tells the SMB347 (the power-management/charging chip in the N7) to do two things: set USB to Host mode, and - as per OTG spec - turn off charging via USB and start driving up to 750mA out to power the OTG device. No single, unmodified cable will ever do OTG and charging at the same time.

People here are trying various hacks to modify cables and/or the N7 to do this, with varying degrees of success and certain tradeoffs.

(I should add that the SMB347 is configurable, and people have figured out a simple kernel hack that stops the N7 from disabling charging functionality when an OTG cable is plugged in. That means it also doesn't power the OTG device, so you'd have to hack an OTG cable or the N7 itself to provide power. More info @ http://mehrvarz.github.com/otg-power-nexus7.html)

---------- Post added at 07:44 AM ---------- Previous post was at 07:29 AM ----------

When I heard some cables were problematic I bought the following OTG cables from Amazon to test; all work fine with the N7, no problems.

Sanoxy $0.78US http://www.amazon.com/gp/product/B005GI2VMG

Sanoxy $0.88US http://www.amazon.com/gp/product/B005FUNYSA

eForCity $1.85US http://www.amazon.com/gp/product/B005QX7KYU

StarTech $5.06US http://www.amazon.com/gp/product/B003YKX6WC

I also bought 3 different cables from dealextreme in the ~$2US range, they too work with no hassles.
[Nexus 7 General] KrisPerry:
OK so I assume this kernel mod would only allow USB changing mode ie not fast ac charge mode.
[Nexus 7 General] Mechanio:
That part us, unfortunately, going to continue to be a problem: high-current chargers short the data pins to tell the SMB347 to enable high-current charging. You'd need a way to disconnect the OTG client (so its data pins don't get fried) whenever you were charging, which isn't any different from what we do now with external cables. Installing a switch to re/dis-connect the OTG data pins while charging allows you to mount the OTG reader internally, something a few here have done.

If power is diverted to DOCK_5V the only problem that still remains is that you can never plug the N7 into a computer as a client unless you can disconnect the OTG data lines via switch as before, AND disconnect USB_ID from GND to kick the device out of Host mode.
[Nexus 7 General] KrisPerry:
With USB low current charging will the device consume more power than the charger can deliver if I am using GPS etc

Hi

Hope someone can help me. I'm currently running stock ROM with motley kernel. Was wondering if its possible to write to NTFS hard drives using stick mount or USB otg helper. I have tried both apps but they only allow me to read not write. Thanks in advance

I don't have too much expertise in this area.

So, what? I buy this cord, and I now I can plug my N7 into things with normal sized USB ports?
[Nexus 7 General] mvmacd:
Yes you buy a microUSB OTG cable and you can plug in keyboard, mice, and if your kernel/rom supports it, flash drives & hard drives.

If you have stock ROM, I hear you cannot mount mass storage [flash drive, etc]. But if you have a CM10 rom, it has support built in for mass storage. Or if you are stock rooted, you can use apps like Stickmount, or if you have a NTFS drive you have to use usb otg helper
[Nexus 7 General] bennor3814:
While not free, the Nexus Media Importer will allow access to external media without having to root the Nexus 7. It does have some limitiations, exFAT and extN are apparently not supported (at this time), nor can you write to the external media it is read only.

What's the best storage with N7 ?

- usb drive (maybe nano stick)

- micro sd

- ssd hdd ( battery drain too fast ?)

I hope someone find a way to power N7 and mount drive at the same time :)
[Nexus 7 General] JaSauders:
Does CM10 support EXT2/3/4 file systems on external drives via OTG? Or is it oddly limited to FAT32/NTFS like stock rooted w/ USB OTG Helper is?

I never understood why Android USB OTG on the N7 requires FAT32/NTFS to work yet EXT* doesn't. That's like Apple OSX requiring NTFS to install OSX. Ya know, one of those 2+2=57 type of things. :silly:
[Nexus 7 General] Svardskampe:
I have looked towards all kinds of alternatives to fix the rather cramp storage space, and the best solution would be to set up my own cloudserver, some FTP-ish solution. Since new devices are kinda getting less and less SD storage spaces, I think this is quite worth the investment. It's also quite convenient to have a central server to take care of your files, as I have multiple systems in the house I can't keep track of all the synchronization and harddrive space lost due to duplicates.

Add: with ES file explorer the barrier between tablet and server is near seamless when I'm on my wifi. Music apps just pull their music from the server like its nothing, no extra effort at all :). And when I need something offline, I can just copy it on the go, without having to connect any wires and all that.

[Nexus 7 General] dmexs:
I'm assuming by the DOCK_5V you're talking about the Nexus 7's POGO pins? Is it possible use these pins to supply a full charge (not trickle) and use OTG host mode to mount a USB device via the normal micro USB port? Does http://mehrvarz.github.com/otg-power-nexus7.html help with this at all? (Using the POGO pins to supply a full charge, not a trickle charge.)
[Nexus 7 General] dmexs:
Tried some things this morning and I believe the answer to my question is unfortunately no. The POGO pins don't allow simultaneous full charge and OTG host mode. The best I was able to get was "Not Charging" in the battery settings panel. Sigh...add me to the list of frustrated car installers.
