Okay so I have an OTG adapter.
I try one USB Flash Drive which works fine currently, but my other, the one I had just spent all night uploading files too, comes up as corrupted when I plug it in.
It still works just fine in my computer, no errors found, so I don't know what's wrong.
Does anyone know how I can fix this? Without reformatting.
Misleading title - you say corrupted SD card but are talking about using an OTG adapter.
In any case if you're talking about a USB flash drive or a card you're reading via an adapter: If it were me and as you have stated - it works fine on the computer - then I'd copy all the files off to my hard drive using a computer, format the flash drive/card in exFAT format on the computer and then copy the files back onto it using the computer . . and then test it on the device via USB OTG. You could just copy a folder or two onto the reformatted flash drive first just to test to see if things are going to work as expected before going through all of the effort of copying everything.

Has anyone tried setting up their sdcard to be a bootable USB Drive that oyu can boot a PC from?
Idea being:
1) Install bootable systemrescuecd or memtest on your sdcard
2) Plug your phone into the pc via usb, mount your sdcard as usb mass storage
3) Turn the computer on and have it boot systemrescuecd or memtest from the phone's sdcard.
I've tried it, but my desktop, eeepc or laptop do not see the Captivate's USB mass storage as a boot device. It has been done on a G1 (since I can't post links, google "g1 pc boot" and click the first link) and I'm trying to do the same on Captivate.
Any ideas?
I dont know, but it seems to me that you would have to make the internal sd card in it bootable. I'd try using the HP USB formatting tool. I use it all the time to make usb thumbdrives bootable. After doing that I'd think you might be able to boot from it.
I did. I didn't use the HP one, but I used multibootisos, which worked fine on my physical thumbdrive. The same process didn't work on the captivate.
Possibly a partition of the drive might work. Then you could format iit to work for your needs.
Nice idea btw

I'm thinking there is an issue (atleast with my phone) showing up as 2 drives. I dunno, I'm fussing with it and getting nowhere.
You get two drives because you have the internal memory and external memory mounted.
When you boot you computer, you need to be able to select the specific usb device to boot off of in bios. Usually you can hit F12 during boot to select it.
Right.. as I said, it worked fine with the physical thumbdrive.
I get why the captivate shows up as 2 devices.
I know how to select the boot device and all that. I'm saying neither of the captivate drives show up as a bootable device despite being setup exactly like the physical thumbdrive that does work as a boot device.

Not 100 percent sure but i beleive someone said that you need to boot the device with the usb plugged in for it to recognize some drives?

It should be listed as usbdrive using your favorite file manager. Usually under
...
...
sdcard
sdcard2
usbdrive
Its not like windows. It doesn't pop up with a window when you plug it in. Flash drive must be formatted fat32. Android doesn't like ntfs

I do see the USB drive bit it's always empty. USB drive is fat32 formatted.
Using a USB mouse works great. I don't get a popup which notifies me about a connected usb drive like my archos 101 did.
Did a little discovery:
When connecting the tab to pc with a usb cable only then a "mount usb" message pops up.
Then a usb drive will work.
Now how do i get the gtab to mount the usb drive ?
I don't think any of these roms are gonna give you a popup when you load a usb drive. I just plugged one in on tnt 3.1 and it reads it thru file manager. I was on vegan beta4 and did the same thing yesterday
Edit: usb disk not usb drive
When you connect a cable from your pc to the tablet the pop up is to allow the tab to unmount the internal sdcard so your pc can read it.

I do not understand...what is location of the usb files then ?
Open iFileManager and hit the icon that looks like a house. Scroll down and you will find a folder named usbdisk. That is your usb drive. Open the folder. I'm assuming the usb drive is plugged in

/usbdrive is empty.
It becomes populates when i insert a mini usb cable and connect it to the pc.
This give me the mount option and only then i see files under /usbdrive.
idk then, I never had a problem reading the usb drive on vegan beta4. Sorry I can't help
OK, found it.
I have to unmount the sdcard first. Then the usb drive shows with files.
Thanks.
Cool....You may wanna drop a note in the vegan thread on what you did. Maybe others have had the same issue.

Hey. I just got a USB Flash Drive and tried connecting it to my GTab but no dice. I am running Vegan 5.1 and using ES File Explore. I navigate to the root directory and see sdcard, sdcard2, and usbdisk. Sdcard and sdcard2 has my internal storage and my micro usb storage files respectively. But nothing pops us in usbdisk. I tried removing the microsd, rebooting with the USB inserted, and unmounting the microSD but no dice.
Any hints?
Thanks,
Scott
Update: So I tried going to settings and unmounting the sdcard and now I can see the USBdisk. Odd. If I want to transfer data from one drive to another, I cant accomplish that because the SDcard is unmounted. Also all my appdata and stuff are not present. Any way to have both of these drives mounted at the same time?
Thanks
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.
i am using micro usb male to normal usb female.
cable is gold plated and branded.
but others have also mentioned that usbotg not working after they updated to 3.2
though i never tested on 3.1

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
Hi All
I have tried a USB Flash drive on my Moto G, and I am able to read all files fine on the device, however I can't write anything to the usb flash drive. I have rooted and tried Stickmount, but this isn't working still. Just wondering if anyone else here has any ideas or success? Thanks in advance!
-J
*Edit - It seems to be working now! See post 5. Very strange!
Others have the same problem, not me, I can write, read here:
http://forum.xda-developers.com/showthread.php?t=2537439
Usb Stick has to be formated in FAT32 and not NTFS. This is maybe your problem.
Hi, thanks for the replies! I am formatted in fat32, and I'm using one of those small Meenova microSd card readers. Shaftenberg, what size if your microsd, and how is it formatted? I am using an 8gb one, but still have no luck.
OK this is weird...after fiddling around with it, I've managed to get it working! Basically I formatted the drive to exfat, tried it with stick mount, didn't work. I then killed all the stick mount processes, and manually deleted the 'usbStorage' directory. Reformatted the microSD to FAT32 on my computer, then I tried it again. Stickmount automatically mounted the microSD, and this time, I was able to write to it! Don't know why its decided to work, but very happy that it does. I tested copying files across, now downloading a linux torrent directly to it, and its working great.
Glad you got it working
I had a 4GB USB stick with fat32.
I have a weird issue when trying to copy multiple files from pc to phone, using an USB cable. In about 95% of cases, the copy process gets stuck at a random file... ("Copying..." and the file name is displayed meanwhile). After some time I get an error message "Cannot copy file <file name> . The device has either stopped responding or has been disconnected. Stop copying? / Skip this file / Cancel" . The file is always a different one.
The more files I try to copy, bigger the chances to fail. If I choose Skip, the copy continues but chances are it will get stuck at another file and so on.
Files are pictures, movies mp3s, it doesnt't seem to matter.
For the moment, the workaround is to repeat the copy process until the number of files in destination matches the source...
I can copy just fine anything (lots and lots of GB) from phone to PC, using the same USB cable, without adjusting it, before and after the failed copy from pc to phone.
Phone is Samsung S10e up to date
PC is a Windows 7 x64, all 4 USB ports behave the same.
USB cable looks fine as far as I can tell
I wonder if someone experienced something similar or has some idea on what to check.
For the next week I am limited to the hardware mentioned above.
What prog you use to copy?
Update:
Changed cable, no difference
Tried on another win7, same behaviour (error copying to phone, on random files)
Tried on win 10, copy from phone fine, copy to phone does not show error, yet randomly some files are not copied to phone (?!).
I used windows explorer to copy.

Make sure you get a high quality cable. Post a link to where you purchased your cables to warn others ^^
Both of them are original Samsung cables.

wow.
Having experienced similar troubles copying from PC (Win10 x64) to previous phones (S4mini) via USB cable, I now avoid this method. Instead, I copy files from PC to 64gig microSDcard in a USB thumb drive adaptor. Then I put the card into S10e and sometimes copy from card to internal storage. It's actually faster this way than from PC directly to S10e internal storage, especially when I want the files on both of my S10e's. This phone is really fast moving files from its external to internal storage.
