USB OTG Hard Drive not recognized - Verizon Samsung Galaxy S 4

Hi, I am usign custom roms for my phone. I have a external 1tb external hard drive that I want to save all my backups into through TWRP. When the phone is on either AOSP or the Standard Touchwiz Rom, I am able to access the hard drive through Root Explorer and Change things whenever. When I go into TWRP, however, I am not able to acess that Hard Drive. I am on TWRP 2.7.0.1 right now. I was not able to check mark to mount the item and when I tried switching to OTG usb cable, it wouldnt acess the Hard Drive in TWRP. How is this possible? I was able to acess flash drives in TWRP (but their size is too small and its useless). I really want to use my big hard drive so I can get some extra space back on my phone again. Thanks for the help!!

The 1TB hard drive is almost certainly formatted NTFS (or, less likely exFAT). TWRP is evidently not recognizing it.
You could reformat the external drive as FAT32, but it won't be able to handle large backup files (more than 4Gb).
Or, you could reformat it as Linux ext4.

[Q] USB OTG support in recovery

OK, so the DNA has support when booted into the OS for USB OTG cables/thumb drives... is it a pipe dream getting the same feature in recovery?
I've tried with both TWRP and CWM to no avail. When in the phone's OS, the mount point is located at: /storage/USB but that doesn't appear in either recoveries.
My reason for asking is simple: Considering the DNA's weakest feature is the storage space (both the relatively small amount and lack of SD Card slot), it would be beneficial for many to enable it so that when performing nand backups, ROM/Mod/Script flashes, etc. in recovery, one could actually store all of those items on the Thumb Drive rather than the internal storage. I'm finding it very painstaking to have to perform these types of items, having to copy/paste/move/delete them on and off the phone's "SDcard" folder... it's also somewhat of a risk if your phone somehow gets hosed and you didn't move your files off of the phone prior to the hosing.
HTC may not have given us more storage options (dare I say like the iPhone, where you can get 32/64gb+ space), but with USB OTG we can use a thumb drive as our sdcard.

Have you tried poking around in /dev or similar folders for the drive?

UMS on Android 4.3 gives "Please insert disk into removable disk"

Hello,
When I updated my S3 to 4.3 from 4.1.2, it was terrible. It was very laggy, my screen didn't show when pressing the Power Button or the Home Button, and I thought that resetting to factory might fix it. Well, I was so desperate to make my phone work better that I didn't realize that all my files were on the internal storage, I don't have an SD Card. So, I've lost everything.
Now, I'm trying to recover some photos, but I can't connect my phone as USB mass storage to use a recovery soft on Windows 8. I rooted my phone, installed USB Mass Storage Enabler app, but it shows two drives (H: and I, but I can't access those. It gives me "Please insert a disk into Removable Drive (LETTER"
Please help, I did everything I found on forums, but still nothing. Those files might be lost, but now I have another battle.. Making my phone available in Mass Storage.
And by the way, it still works terrible with 4.3. Hate it so much!
Have you installed USB drivers ???
Have you read the stickied storage/ recovery thread ??

Unfortunately I think USB Mass Storage in the way it is implemented in 4.x for the moment can only share the external SD, the internal one is never visible.
IMHO the only approach to recover "something" is to get an external microSD larger than the internal partition and create a block copy (with dd under adb in CWM/Philz recovery for instance) of the entire "internal SD" partition - that one will be an EXT4 (Linux) partition) and there is a very, very small chance that you might recover some stuff from it (I doubt but who knows).
Yes, i have the Samsung USB Driver for mobile phone (1.5.29.0)
No, didn't read the storage/recovery thread.
Oh well...
Such error happens if transfer breaks unexpectedly. Think what file did you send lastly and delete it, it should fix your issue.
If you can't remember or it did not, formatting your external sd card will fix it for sure.

Ah, you're talking about internal one.
Well, then your magic program doesn't work properly. Perhaps you could try boeffla kernel and it's UMS.

Is there any way to use my phone's internal sd card as a boot drive?

I have a Galaxy Prime 3 which is basically a cheapo version of the Galaxy S5. On my old S5 I had TWRP installed which was extremely useful for mounting the SD card as a USB drive and then plugging it into a PC to boot from it with install iso or utility iso.
It is not possible to get TWRP on this J320A as far I as have found, and the only app purporting to do boot from sdcard over USB (drivedroid) did not work for me. Is there any way I can use my phone to boot a PC over USB cable? I know its much "simpler" to use a flash drive or burn a CD/DVD but I like hacking things to their fullest. Any suggestions?

Help with my N9

I was running the Pure Nexus ROM but took the decision to try a new one, that's when the trouble started.
Before semi bricking the N9, i updated the version of TWRP on it to 3.2.1-0 and installed supersu as it wasn't rooted prior to messing it up.
IO think the trouble started when TWRP was asking for a password, and it didn't match the PIN i had setup. Anyway, i d/loaded slimrom 7.1.2 and gapps to root of SD card, did a factory reset and wiped, system, dalvik and cache. When i went to flash the new ROM, i couldn't see the zip file in the root folder.
If i look at the root folder in recovery, i see one of the images below and the other when rebooting the tablet.
When i try to connect the N9 to my windows 10 PC it is not being detected, i don't know why do to about this to try and go down the adb route.
I have installed Android Studio to try and move things on, but i don't know what to do next, or even if anything can be done.
I am almost sure i had the OEM unlocked before flashing the rom.
Can someone suggest what i should try next? I won't be able to check back in for a day or two due to work, but i definitely will when i get the chance.
TIA
Did you format data? To remove encryption. Format, not wipe.

Gave it a go, no luck unfortunately. The sdcard is as the attached image.
I have ordered an OTG cable, hopefully i will be able to flash a rom that way on TWRP.
Edit: i was able to borrow an OTG cable. I formatted it FAT32 on windows PC and copied across the rom zip file. I rebooted into recovery on N9, and tried to mount the usb drive, but it is not appearing on the list of devices. When i pligged the same OTG cable and attached usb drive into my phone, it picked them up, so i think the otg cable i am using is good.

If you formatted data, there won't be anything on sdcard. You'll have to either push it with adb, or as you said otg.
Or download the factory image and fastboot flash to start over. Or sideload the full OTA zip (they have full images of ota zips now).
Got it sorted in the end. Embarrassingly the reason the tablet wasn't detected by my Windows PC is because the cable was a little lose.

At least you got it. And a little tip, you can screenshot in twrp just like in the os. Power + volume down

How to Emulate windows to show as usb device on Android

Ok so this is what im trying to do... I want to backup TWRP backups and swift backups directly to my windows 7 pc but it seems the only way to do that is to have a USB device. I know i can backup to an actual USB device and copy or move it from there but i go thru otg cables like crazy and atm i dont have a WORKING one so i wanted to backup directly to pc. Is there a way to emulate a thumb drive on windows to connect it like that in situations like this?
It is not possible. You can only backup via TWRP to internal memory, external microsd or via usb.
Thank you. I appreciate that.
