When I connect my GS3 to my Asus Transformer via USB I can not see the internal or external SD card. Eventually I get a message on the GS3 that I need to download Windows software for my PC. Is there a way to simply connect these two devices via USB?
Question question regarding USB OTG Cables/Micro SD Card Readers. I know you can view content on them (movies, music, documents, etc). However, can you write to the flash drive/micro sd card? Basically, I'm curious because I know I could store roms on the flash drive or micro sd and play them from there, but I would like to store saves to it as well (so saves would not have to be stored on the Nexus 7).
I'm interested in the Meenova MicroSD Card Reader (I go for the card reader over a USB OTG because I do not need a large flash drive - a 64GB micro sdxc is sufficient), just curious if I can write to it as well or only read.
Thanks!
I've had no trouble writing to my Kingston 16GB SDHC through a usb reader.
The only thing I would mention is that you'll need a custom kernel to access NTFS file systems. Also you should note that the kernel in question needs to have write enabled for the NTFS module. This had me stumped when installing a kernel without it enabled, and it only ever mounted it read-only. Of course, if you're using FAT then you don't need to worry about any of this.

I'm close to purchasing the Nexus 7 2013. The one thing holding me back is the USB drive issue. I want to be able to access the drive via the microUSB port and read&write to it like I would on a PC. You know, open an excel file, modify it, and close/save. All on the USB drive. Are you saying that can be done easily enough? I don't mind rooting, either. Don't want to but can if necessary.
Thanks. So from your post and reading a few other posts, unless you're rooted, you cannot write to NTFS (only read), but you can write to Fat systems. I really don't plan on having any files greater than 4GB so I believe Fat will work. Thanks!
I recently got around to unlocking and rooting my nexus v2 and every time I plug in the otg cable with SD card it will not pick it up but yet when I plug in my 2tb passport it picks it up but it will not let me play off it any suggestions

You're using an SD card reader, I gather? I've tried two (with multiple cables) but never had luck with SD cards, only flash drives.

Go figure all that work just to get a flash drive
A flash drive is less convenient than the SD card you already have, but it doesn't need an adapter for the USB OTG cable.
Maybe this will help--or not. I have been able to access an SD card via OTG connector and card reader. It's been a fickle set-up. This is what seems to work for me.
Rooted stock 4.4.4 + Stickmount Pro (haven't tried it without but will in a bit). ATM, I'm on 3.4.0 ElementalX but usually run Franco so I don't think kernel has any effect. Connect all hardware--card in reader, reader and OTG cable, OTG to N7. Reboot the N7. When it reboots, Stickmount shows that the sd card has been mounted. From ESFile Explorer, I can go to storage and see the card plus access it's content. I can unmount and remount the card, but if I unmount the device and remove the OTG and/or card, I have to reboot before it can be remounted. You can see in the pic which reader and which card I'm using. If it works without Stickmount, I'll report so. Otherwise, assume Stickmount is required.
I have purchased a week ago a Galaxy Tab S 8.4 (T705M) and I am using a 64 Gb MicroSD in it.
I upgraded to 5.02 (OTA) since June/26.
I have problems with external MicroSD when the tablet is connected via USB to my PC (Windows 7, Home, 64 bits).
Whe trying to copy files from the PC to the tablet external MicroSD, the operation is very, very slow and some files (existing previously in the external MicroSD) disappear. Very annoying.
I had same problem with another Tab S I purchased by January and I returned it to the vendor. In that case, the tablet was on Kit Kat (as it is sold).
Yesterday, after the Tablet erases several directories from the SD, I turned off the tablet and extracted the SD. I tried to fix the SD directly connected to the PC but the SD appears as "read only".
After trying for a while I gave up and I formatted the SD (extFAT) and copy the info from a backup I did before putting the SD in the teeth (fangs?) of the tablet (yeah, I guessed the tablet would be as a wild beast when managing SD's). The "re"formatted microSD behaved as a charm, all info copied without any problem (but it took almost 3 hours copying 50 Gb at about 7 Mb/second).
On the other hand, I used this same SD card in my old Note 8 (Jellybean) for more than a year without problems.
Now, I guess the only way I have is extracting the SD card and edit its content only connecting it directly to a PC.
What can I do to calm down the beast and edit external MicroSD connecting the tablet via USB without losing information and with a reasonable speed ?
Any suggestion ?
Root your device and apply the sd card fix. Also 7mb/s seems about normal for a cheap micro sd card.
I have not had any problems with files disappearing, have you confirmed your 64gb microsd is not a fake.
I have a Samsung 64gb microsd, and i got around 9MB/s copying a movie from my notebook to my T800 10.5"
John.
Thanks for the comments.
My card is Verbatim Class 10 and it worked perfectly in my old Note 8. It works really as stated for a class 10 SD (10 MB/s at peaks as stated in https://www.sdcard.org/developers/overview/speed_class/) but, as with any device, speed depends on several factors (file sizes, buffer in the source PC, etc) and the average obtained is really about 7 MB/s or so.
I guess the problem is related with something in Lollipop (but Tinderbox says has no problems) or, more probable, driver in the PC.
Tinderbox, are you using Kies to transfer ? are you transferring from a PC or a Mac ? which class is your SD ? have you enabled "USB debugging" ?
I purchased an 8 GB SD in order to make some tests. This SD is Class 4 and formatted FAT32 but anyway I will test it to learn about this riddle....
In the mean time, any suggestions are welcome and I repeat, thanks for the answers.
UPDATE:
Sandisk SD (8 GB, FAT32) worked perfectly, no erases, good speed (Class 4, speed tablet connected via USB about 4 MB/s).
Next test planned: reformat Verbatim 64 GB using FAT32.
I am on kitkat 4.4.2 and i dont use kies, I just drag and drop my files from my notebook to the tablet, I did not need to enable usb debugging, my 64gb is full of video, I copy them virtually every day and have had not problems.
I think i read about another 8.4" owner having problems with his microsd card i will have a look for it.
I have only ever bought Samsung memory cards for years and i have never had a problem.
Have you tried re-installing the device driver, you can do it from the kies menu.

Thanks for your complete answer(s).
I have made several (a lot) of tests without any success. In all cases SD can not be written from a PC (when connected via USB) and erasing files using android app sometimes cause corruption.
The card is completely readable (a little laggy to begin to work after it was unmounted and reinserted). The card works without errors when connected directly to the PC.
These are the some tests I have made (reformatting and restoring the files between one test and the next, a real nightmare ):
1. Uninstalling Kies
2. Reinstalling Kies (and refreshing driver)
3. Uninstalling Kies and Samsung driver. Uninstalling USB driver and erasing it completely and let windows select the driver
4. Formatting the card in FAT32 via some software
5. Trying to format the card via command in windows (from the console). It takes about one hour and abort near the end with an error messages explaining that windows can not format FAT32 for this capacity
6. Even trying to partition the SD via DISKPART. I can create one primary partition (32000 MB) but DISKPART shows all disk allocated and do not allow to create another partition (either primary or extended)
Last symptom: I erased one file from the root directory of the SD using "My files" (the app preinstalled in the firmware by Samsung). The file disappear but My files shows a ghost file named with special characters.
When the SD is consulted via Root Explorer (an android file manager) or even connected directly to the PC, the ghost file did not show.
@tinderbox: could you remember who (or where do you read about) the other " 8.4" owner having problems with his microsd card " ?
Some body could suggest solution ?
Thanks for any help or guide.
Hi.
You did format the micosd card using the tablet, you cannot format on an computer and then use it in your tablet, the tablet uses it own file system, so you have to format the microsd using the tablet.
John.
Format the card to exFat in windows. It only takes a few seconds to format my Samsung Evo 64gb.
If it doesn't work then your card likely has issues.
Finally success
Thanks for your suggestions.
I tried almost everything:
1. Formatting FAT32
2. Reformatting in the tablet
3. Reformatting in the PC
4. Even formatting using a software from Verbatim website
The problem persists: SD Card is not editable (delete files, write files, edit files) when inserted in the tablet. SD works perfectly in the PC.
Finally I purchased another SD 64 Gb Toshiba Class 10. The SD package says it can work at 40 Mb/sec. The card write at 10 Mb/sec but it reads faster.
This Toshiba card works perfectly. I can erase or move files using android file manager (My Files app), I can write from the PC using tablet connected via USB to the PC. I can create files directly in the tablet (I used Jota+ to create a text file).
Verbatim card and Toshiba card specs seem identical, except by the speed claimed in the Toshiba package. There is some difference I am missing but definitively these cards are not equal (something in the card data bus ?)
I repeat, thanks to everybody who tried to help.
I only ever buy Samsung memory cards for years, and i test every one for errors and i have never found any, And if an Samsung memory card does not work in an Samsung tablet, well it is not going to happen, but people go for the cheap alternative.

Plan:
Minimalist data redundancy while photo-backpacking-airbnb-ing in Iceland and Scotland later this Summer. Plainly putting maximum effort into NOT having to take my 2010 15" MBP for backing up DLSR & HTC10 Stills and Footage. Shoot>Backup from Card Reader to internal 128GB Internal card via OTG>Export via OTG Cable to 1TB external and to Google Drive if/when WiFi available.
Gear:
*HTC10 (duh, ahhhmazeb***s so far after only a few weeks! RIP to my M7)
*Type C Adapter, RAVPower USB C To A Female OTG Cable, USB-C On The Go Convertor for New MacBook and Other Devices with Type C USB
*Lexar Professional 1800x microSDXC 128GB UHS-II W/USB 3.0 Reader Flash Memory Card - LSDMI128CRBNA1800R
*Transcend StoreJet 1 TB Military Drop Tested USB 3.0 External Hard Drive (TS1TSJ25M3)
*Nikon D4, Tammy 15-30, & 70-200
Troubleshooting So Far:
* Formatted Lexar as Internal, no problem...though since I have 8GB of space left on the built-in, it's only theoretical space at this point. (Maybe don't format as Internal?!!?)
* Shot test images with DSLR and was able to import from XQD and CF card readers to the internal SD/'0'/'Downloads' folder via OTG. I am now stuck trying to get the images off. Many of the RAW (.nef) files appear corrupted by the NEF Thumbnailer App. Of the few that I tried to transfer I could not see the external drive. It shows up at 1TB of usable storage after the 'Unrecognized please format device" error, even though it's formatted FAT32, ExFAT wouldn't work, or vice versa, I forget which.
* My go-to Astro File Manager (free version) doesn't see the external either. (Though I didn't try to 'Add Location' yet. Do I have the drive on me now...no. Bah. )
* Lightroom Mobile will not recognize it either and/or Edit .nef files...but it edits the HTC10's DNG files flawlessly which I LOVE! Would love to be able to edit my .nef's on the go, but that's a gripe with Adobe, not Android. Again cannot export to the 1TB External, that's the rub.
* For giggles I connected a Mouse and it actually worked on the OTG cable and the handful of fellow IT cohorts had some Friday-afternoon-geek-out giddiness last week. :highfive:
Thoughts based on limited Googling:
* It's a hardware based issue - The OTG cable I bought for $10 is crap and only partially works.
* It's a USB 3.0 vs. 2.x issue (supposedly this was possible on non-rooted Galaxy phones with a USB 2.x OTG Cable using The Thumbnailer App based on a post I found from a photographer back in 2013-ish.)
* It's a software issue and I need to root, which I've never been fond of.
* My other slightly unrelated concern is that my DNG's are not syncing to Google Drive. JPG's are there. Google Drive allows for DNG's supposedly?!?!
Thanks in advance for all that you do....stay awesome!

one thing to help out out is in your file explorer while the external cannot be accessed from it normal location. you can go to Root>Storage>"name of card" and be able to save/ upload from your sdcard there

Thanks afuller42. Do you mean while the External Hard Drive is not connected via the OTG cable... attempt to access the SD card Downloads folder? That's where the test photos are now?!?
Dear Ryan,
1. Make sure the OTG drive is formatted in FAT32..
2. If you are to utilize OTG memory on your hTc 10 - do not use any BS file manager - but only authentic hTc file manager:
https://play.google.com/store/apps/details?id=com.htc.filemanager
3. Make sure hTc file manager is running in foreground - before you plugged your OTG memory
4. Follow the normally needed steps by selecting OTG storage and granting the drive writing_permitions to hTc file manager.
5. Enjoy ?
