external hdd to galaxy tab 7.7 stock jelly been - Galaxy Tab 7.7 Q&A, Help & Troubleshooting

I can get the external hdd to be read by my tab I've hooked it to a USB reader and is powered 5v and it's still saying blank USB drive detected, and I also have the drive in two partitions fat32 and ntfs format Nothin picks up, and have downloaded apps to assist in it to be recognized still Nothin, I'm running stock rom jelly bean 4.1.2.any help out there thanks.

Firstly,make sure you have Root access..
get super user.
download paragonNTFS from the playstore..
Connect HDD to the Tab..via usb otg host dongle
Open Paragon App,grant permissions to superuser..(remember forever)
it will either auto mount your drive to /external sd card or /usb drive or you can mount it manually to where you want to mount it.
The thing here is Ive never tried a HDD with a FAT32 and NTFS partition on the same drive before.not sure if this will give probs but should be able to do it.Try removing any external sd cards and look in location of external sd card for content of fat32 partition.you will always have to mount the NTFS partition with something like paragon it wont auto mount by it self like fat32 does..
Check settings / storage and look for your hdd volume info there
if its not there then you have problems.

P.S..
How exactley are you powering the Hard drive?
make sure its not connected to the power wires of the usb host cable
adding power to this seems to upset the host connection for me.
for a 5v hdd you would have to use a powered hub or from any usb as long as there is a seperate power source plug for power and differnt plug for data.
the newer hdds seem to have gone this way now but the older ones dont use this and run power through the data lines power source.you can try use a y cable for that type of hdd but run through a powered hub would be better.
maybe through up a pic of what you are running or some more info eg what drive and app to mount it.stick to paragon it works for tab 7.7.no need for anything else.

This is my set up,I'm rooted on stock though.

[Q] USBOTG doesn't work

Hi to all!
Here's the problem that I have.
After upgrading my Xoom (US 3G) to Tiamat 2.1 Hammerhead USBOTG stopped to work. When I try to connect flashdrive via this cable it blinks only once and that's all. The folder USBOtg is empty -> nothing is shown (but I know that there are files). I tried to format flashdrive to various filesystems (NTFS, FAT32) -> no result.
Another strange thing after upgrade is with MicroSD folder. It shows me only old data. All new one that I copied to it via PC it doesn't show at all. AND!!! PC doesn't see the content of folder with name "external" on Xoom but when I copy there files from PC then Xoom can see them.
May anyone advice any steps to return usbotg and microsd in normal working state?
I tried to re-flash Xoom with previous various versions of firmwares (mods) -> the same situation.

Two different issues--if you read the release notes with the Hammerhead Rom, Team Tiamat removed the USB Mass Storage enabling that had been in earlier Rom, due to various difficulties. So that means you can no longer use your PC to copy files into the micro sd card in the Xoom, but you can cop files directly to the sdcard using an adapter or card reader. Your Xoom should still have access to the files on your micro sd card at mnt/external1.
The usbOTG works fine for me but it needs the help of an app like USB Mass Storage Watcher OTG or Drive Mount. Both will work. It also helps to reboot with the drive plugged in the first time if you are having a hard time getting the Xoom to recognize it.
Thanx! Drive Mount helped me with recognizing and mounting flash drive (but only after Xoom reboot with drive plugged in). USB Storage Watcher OTG crashes everytime when I start it with drive connected -> with disconnected it starts normally but won't see any after-connected drives. Ssems that I'll use Drive Mount program
As for MicroSD -> even connected directly to PC and copied some files to it Xoom still sees only old data. Any ideas?

Actually, try checking the folder mnt/external1 (1) as this is HC3.2's official mount point. The Microsd mount point is an artifact of an older Rom.
i am using hammerhead rom with tachi kernel.
yup the usb otg not working.
tried both usb watcher and drive mount.

Make sure that you are using a REAL usbOTG cable.
A real USB otg cable? What needs to be special about the cable in order for it to work?

This is where I will suggest that you do some research. Start with this forum and then search elsewhere. Just today I have answered this question 3 times. Search on my name and you will see my posts with your answer.

Your cable will never work because it is not OTG. OTG has a different pin configuration to allow the Xoom to function in usb host mode. If you are handy with a soldering iron you could make one, but why not buy one, they are availble. Here is my Google search for USBOTG Xoom to get you started: http://www.google.com/search?hl=en&source=hp&q=usb+otg+xoom&aq=2s&aqi=g1g-s9&aql=&oq=usbOTG

Any roms work with NTFS external HDD

I have tried EOS and CM10 but system can't recognize my seagate 1.5 TB external hard drive. It shows something connected to the device but can't mount it and can't see the content.
I use external power for the hard drive so I think the power should not be a problem.
Is there anyone have any ROMs suggested that may work with NTFS HDD?
Thanks,
HJ

[Q] Need some help with OTG

Hello,
I just bought a SD-Card USB reader, an active USB hub and an OTG cable. I want to copy my holiday photos from SD Card to an external USB HDD via Nexus 5 with current CM11. The HDD has 160GB. When I plug in the SD-Card USB reader directly or through the USB hub I can read, write copy files from or to it. My 160GB HDD doesn't work. I tried to format it with FAT32, exFAT or NTFS in different sizes. I used ES File Explorer. There I can see both USB devices but when I try to access the USB HDD ES File Explorer loads and loads an loads but nothing happens more...
How do I ahve to format the USB HDD to get this working? Are there any limits on size, format or even hardware?
I think cm11 on nexus 5 cannot handle two otg storage device at once. Try stickmount app from playstore.

otg usb write access

OK, I've been able to connect my USB drive to my phone and view movies and files, but today I wanted to write to it and it says permission not supported. I use stickmount and ntfs mounter to mount and have tried es file explorer and astro. Neither will let me transfer files to USB... I have had the sdfix installed forever now, and I can write to my SD card, but just won't let me write to USB through org cable... Any help?
The only USB drives I've been able to use OTG with the M8 are flash drives (which don't require external power). Are you using something that needs power?
I've used powered and an unpowered western digital my passport 2tb harddrives and been able to watch movies off them even in ntfs format, but my ntfs USB flash drive will only read, no write at all... I'm going to try formatting it back to fat 32 and see if I can write to it when I get home. I thought i wrote to it before, but i recently formatted it to ntfs to put a movie on it... I'll post back tomorrow.

[Q] Mi 4i USB OTG Not Working

Hi,
I am extremely sorry if this is not the right place to ask this.
I got my Mi4i on the first flash. As soon as I got the phone, I did the MIUI 6.5.3.0 (LXIMICD) update. I did not check the USB OTG before the update, so not sure if it worked before the update or not. When I tried USB OTG, the Mount USB storage option is greyed out - always. I tried 2 different USBs and 2 different cables - still no luck. I am starting to suspect if its something wrong with this ROM release, as lots of areas in the setting is greyed out for me (for example, in the Headphones and Audio effects settings, the equalizer settings are always greyed out). So, have any of you tried USB OTG on MIUI 6.5.3.0? Any insights?
Yes I can assure u that USB OTG is working fine on MIUI 6.5.3.0
Check if the USB is a fat32 or ntfs?
Ntfs file system doesn't work with mi4i
Format the pen drive in fat32 and try again
I also tired a sd card reader it works brilliantly
Audio settings will be greyed out until u plugin headphones. Try any earphones or headphones then check if it still is greyed out

Thank you for the reply but I am still facing the issue...
Yes, the file system is Fat32 and the mi4i is still not recognizing the USB. Since the USB OTG is working fine for you, I suspect my OTG cable might be damaged ( weird- I tried 2 different cables).. Maybe I should try a different OTG pen drive?
PS: You were right about the audio settings, those worked when I plugged in the headphone..
same problem here.keyboard and mouse working but no usb drive with same otg cable. Otg card reader also not working.

If you're USB or SD Card is of huge capacity it may take time to load so I would suggest you to wait for a while, Android checks if the storage has an errors. It doesnt show in MIUI though. But wait for a while after plugging in.

I have sandisk otg 64gb and it works without an issue. Make sure it is formatted with FAT. Other FS like exFAT and NTFS wont work, not sure about Fat32 though.
Hope this helps.
I bought a new 16gb Sandisk 3.0 OTG usb and its working fine for me now.
What's working:
* FAT formatted USB flash drives
* USB Mouse
* USB Keyboard
What's not working:
* NTFS formatted USB flash drives
* Portable USB hard drive
* USB Gamepad
I have an OTG cable lying around. Will soon test Linux file systems (ext2, ext3, etc.). Give me more suggestions, and i'll test it on the Mi 4i.

Aren't there root apps which enable ntfs support by installing a ntfs-3g driver?
The functionality is kernel-baked and not all kernels support the ntfs-3g driver. Also Xiaomi seems reluctant to release its sources anytime soon. There are alternatives like Stickmount however.
