Does you external HDD have it's own power? I would expect the Nexus 7 to not be able to power a physical hdd vs a usb flash drive.

If your external hdd is formatted NTFS, you will need a custom kernel. Or reformat the hdd to FAT32.

USB Hard Drive connection

Has anyonebeen able to connect successfully an hard drive to TP?
I've tried by all manners without success,even with the docking ... no luck.
Would thisbe possible if we root TP?
for your usb drive to be mounted by the thinkpad, it has to be formatted in fat32. not fat or ntfs.
Ive got 2 hard drives (1terabyte and 500GB) with loads of data on them and are both formatted ntfs. I connected them to my thinkpad, they powered up but did not mount. I wasn't ready to reformat my hard drives with data on them so i didn't try.
However, I think I've got a 2GB usb stick lying around somewhere . I'll format it to fat32 and post some feedback here later.
oh and before trying, go to settings-->storage and enable usb storage devices. otherwise no device would mount on the tablet. even when formatted properly
as darkhandsome18 mentioned, yes but the harddrive has to be formatted in Fat32. Windows XP, Vista, and 7 don't allow you to format harddrives over 32GB within windows. However, you can use a thirdparty utility to format drives that are over 32GB in size to Fat32.
i personally use Fat32formatter (its commandline based) to do this w/my drives.
http://www.softpedia.com/get/System/Hard-Disk-Utils/FAT32format.shtml
i did verify that my 1TB external usb harddrive did mount on the TPT, i have not tried to run any videos or music from it though.

i have tried 4 ext HDD (ntfs and fat32), and all of them is not working.... (except for draining my battery for powering the HDD.. )
but for usb flash drive, that is a different matter, is it easily recognized by my TPT..
there is 1 unique problem that occurred to me, while trying to copy files from/into my TPT, there's a notification that file copy is successful, but when i check the file, it's size is 0 bytes..
this has happened to me 3-4 times, unfortunately, i dont know where's the "glitch" is coming from, as i can't replicate the problem anymore (i haven't got any update at all)
I have 2 different 500gb 2,5" drives. My samsung drive works fine playing music on the TPT. The WD drive I have only works sometimes strangly enough.
Normally when I use playback from hdd I use my supercharger power which connects throught the docking port or else the TPT just gets sucked dry of power as the hdd draws almost 500mA's.

If your external drive is formatted at fat32 and has its own power source, you will have success using it with the TPT. But if you are depending on the tablet's USB port to supply enough power to spin the disks in the external hard drive, you will get varying results, depending on the power requirements for your external drive. USB flash drives work fine because they have no moving parts and a low power requirement. As zeb crs stated, you see a huge power drain on your tablet when trying to use an external hard drive without its own power source.

[Q] Setting up OTG

Hello there, I'm currently looking for a usb OTG cable, will get to test one later this evening.
I have a question: What do i need to do to set up the storage on the tablet side? Do i need to get an app that configures the new storage or is it just plug & play. I'm asking because I will try to test the cable to see if it works. Can I just use Solid Explorer to access the external storage after i plug in the usb cable with the attatched card reader and 16gb microsd hc class 6 card?
My nexus7 3g is rooted, currently on Jr4 Rom.
Oh and another thing.. is the nexus7 limited in terms of microsd size and speed class ?
Thx allot.

Get StickMount from the market - https://play.google.com/store/apps/details?id=eu.chainfire.stickmount&feature=search_result
Plug and Play
Use a file manager to find it
Stickmount is the way to go, but you must be rooted. The Nexus Media Importer app lets you access external storage as read-only. You have to pay, but don't need to be rooted. I'm using a 32Gb microsd class 10 and it works great as read/write and streaming with Stickmount.
64GB Sandisk microsdxc the N7 will read if microsd card formatted in NTFS using stickmount. Mine works fine.

I think I will manage to use it without stickmount.
I'm running a kernel that sais it will automount hotplug usb support. Does this mean that it will automount it just like stickmount pro does?
didn't actually get to test that OTG cable yet, maybe tonight.
Also, what do you think of the Rescan Media app? it's supposed to start the Media Scanner service on android and inform mx player and winamp about the .avi and .mp3 files on your sdcard or flashdrive.

I guess I have to change ROM to get it... Do you now is it possible on CM10?
Yeah stickmount pro is the way to go, my 500GB portable Samsung HDD works fine but wouldn't on my Galaxy S3 until I flash Siyah kernel again, I use Trinity kernel on my Nexus 7 and no problems
OTG cable - External HDD or whatever you use - stickmount pro and away you go.

I'm using "nexus media importer" on my unrooted device. It isn't a free app but if you just want to try it before buying, you can try the dev's free app "gallery connect preview". Make sure your usb memory stick has pictures on it . Open the app before connecting the usb stick. I had to try a few times till the app recognized my cardreader and sd cards. Without root i can't change files on the external memory, but at least i can watch movies and open files from it.
I don't know if the sd cards are in FAT or NFTS. I just take it out of my dslr camera and plug it in the cardreader connected to my OTG cable.

Rooted N7 mounting hard disk drive?

Hi everyone. I am very new to Android and this forum as well.
Just a week ago I got my Nexus 7 - my first android device! <3
I read online that I can root my device and install stickmount to get USB OTG support
I have done that successfully
I am able to use the SanDisk 4GB USB now - great
So I tried to mount a hard drive......but failed
I guess my Nexus has not enough power to use the hard drive.
But the thing is that my drive actually did power on (although with a strange sound continued in background)
Still stickmount failed to mount/detect the drive
The hard drive I used is not a popular one - is manufactured by a company named EIGHT
The model no is UH320
The drive is 320GB
As I read more information, I know that self-powered hard drive should work flawlessly.
I want to ask what is the problem? Any suggestions to get it work?
Or any hard drive that is tested and work with the Nexus 7?
Thanks a lot. Any help or advice would be appreciated
You can try a shorter cable. I have a drive that works on a 2 foot cable but only makes a clicking sound and never reads the drive on a 4 foot cable. External powered drives work OK.

Thanks for your advice. I wish to know if you can show a pic of the workable cable?
for mine, it is the "SANOXY Micro USB Host Mode OTG Cable Flash Drive SD T-Flash Card Adapter"
do you know what filesystem your external drive is formatted in? FAT32? NTFS? HFS+? something else? it might not be showing up because you don't have support for the filesystem the drive is in. small flash drives are usually formatted in FAT16 or FAT32, which is natively supported in android, so those will typically work. larger hard drives may not, since they might be NTFS or some other filesystem that isn't natively supported.
I have checked that my hdd is formatted in NTFS. It is 320gb.

It's also very possible that you have a bad cable. You may want to get your hands on another one to verify.
I have tried to use the same cable connecting to the laptop and it works fine. Anyway, I am going to buy another HDD and see if the problem can be solved. Any suggestion which HDD to buy?
I am looking for a 320gb or a 500gb HDD. Thanks!

Curious about the first sentence... you don't mean that you used the cable to connect the laptop to the hdd, do you? If so, that does not verify that you have a good otg cable.

How to run Fire TV apps from an External USB Drive

After trying a whole bunch of methods, here is the best way I've found to free up internal storage by moving apps to an external drive.
Complete step-by-step Guide with screenshots
tl;dr version:
1. Mount the drive with StickMount
2. Move the files and "trick" the Fire TV with FolderMount
does this work with XBMC?
those thumbnails are filling up the internal memory really fast

Yes, you can move XBMC's data with this method. But since XBMC is so customizable, modifying advancedsettings.xml like JJ-KwiK suggests is a better option.
awesome, thank you!
Sweet! Thanks for the guide.
So this guide will let you run apps from an external?? Sweet i need to buy a new one lol.. Thanks

xbmc run well from external drive
Hi Guys
Just need some input w.r.t. flash drives and external drives.
What is the biggest size flash drive or external drive we can use on the AFTV?
Fat32 or NTFS file system?
Do you need a powered multi usb device to make the external drive work?
Must you use a powered external drive to make it work in the fire tv?
Hope someone can clear it up.
I connected a non powered multi usb device on the fire tv. the Rii keyboard with bluetooth usb and my 4gb flash both worked on it, but my 1.5TB 2.5" does not want to pick it up.

I'm using a 32GB USB Flash Drive and it works. It's NTFS. Spinning disk must be powered externally for both 2.5" or 3.5".
External SSD might work unpowered....I don't have a drive to test this theory.

I have two Toshiba 5400 RPM Canvio that are unpowered 2.5 and work fine, and a Seagate 500MB 2.5 in a cheapie external USB case that works fine as well.
Yeah I don't understand I've just found my Verbatim USB 3 external 2.5" works but my transcend external 2.5" doesn't. Both are the same size and both are NTFS. I checked and they both work on my PC. Guess it's luck of the draw for 2.5". I can't get an external 3.5" to work...Anyone else?

3.5 inch should be 12V so they would need an external power supply. As far as not seeing a powered 3.5 it could be one of a hundred different issues.

Images gone after moving Thumbernails to USB stick
Hello,
I 'moved' the Thumbernails folder, using the advancedsettings.xml method. After a new scan run I see all the movie-descriptions, but I do no longer, see any images. They are just not shown..
Any idea, whats going wrong ? I'm really new to XBMC
edit:
After the scan, I deleted the whole content in Andtroid/.../userdata/Thumbernails. The folder itself is still there.
(6GB usb stick/NTFS)
edit2: solution found!
xbmc: System->File Manager->Profile directory->Database delete the Textures13.db and restart the xbmc.
All thumbnails are displayed again!
I tried this method with NFSMW which is approx 4gb after updating and it copied everything over the my usb BUT when i mount it the game says my usb storage device has no room for an update -_- (even though the directory copied is the most up to date version and capacity is 16gb) also, this method does nothing to free up space on the FTV. I had to go in manually to my android/data folder and remove the directory to free up space myself. Might want to add that to the description.

You are mistaken or did something wrong. FolderMount moves the files AND deletes the originals. If the files are set as "mounted" in FolderMount, it will appear as if they are still on the Fire TV. Meaning, if you "ls" the original directory in /sdcard/, you will see all the original files. However, the files are not actually on the Fire TV. To verify this for yourself, go to Settings > About to see your available free space before and after following my directions. You will see your free space increase.

then how are you guys making it possible ?
must the fire tv be rooted ? before this feature is possible.
i think this is an important topic. as the device is now rooted, alot users would download apps, and they would need the space.
I would like to use USB harddrive with my XBMC.
please advice.

Samsung 128GB USB 3.0 Flash Drive Fit for FLAC music, does it works on the HU?

I want to carry my FLAC music library on the car, and was wondering if the 128GB USB 3.0 Flash Drive Fit from Samsung would work on android Head Units with 4.4.4, or do I need a Lollipop Head Unit?, or maybe a special format for the drive?
This is the USB drive:
http://www.amazon.com/Samsung-128GB...34&sr=8-1-spell&keywords=samsun+usb+3.0+128gb
This one doesnt heat up like the new sandisk 3.0 Ultra Fit
has anyone tried something bigger than 64GB?
what would you recommend for the format of the drive?
Thanks
I've connected an external USB 2.5" rack with an Intel 80GB SSD drive , and it works flawlessly. (my HU is Generic 4.1.1)

one other thing, what formaat are you using? FAT32, exFAT, NTFS?
Again, Thanks
I'm using FAT32, I don't think it will support NTFS, and there's no option to format the SSD as exFat.
it's working...so no complaints
