Trying to copy several, small files from my SD card

Hi,
I’m running into an odd problem.
I have a Google Nexus 7 Tablet. I’ve unlocked and rooted it with the Toolkit. I’m attaching it via USB on a Windows 7, 64 bit system. I’ve installed the PDANet drivers.
I’ve made a back up of my tablet using Titanium Backup. Within the Titanium Backup directory are many small files, that I’d like to copy back onto my desktop for safe keeping.
However every time I copy the directory over to my PC using Windows Explorer, only a fraction of files get copied, I’d say about 20%. I’ve tried it several times, but, can’t seem to get it to do a complete copy. I’ve tried selecting the entire directory and the all the files (select all) without success.
When you plug in the micro USB cable to your tablet, does it automatically go into mass storage mode (though I have selected Mass Storage mode as my option).
I’m coming from several Samsung devices and I know there are a few ways to enable mass storage mode on them, and at a minimum, you have to choose to mount the SD card. Is there something similar with Asus devices?
What am I missing?
Thanks!

I rarely send files via the USB port... normally just use the wifi connection. Just sent all the TI backup files via AndFTP to a server over WiFi and it only a little more than 5 minutes.
I then for the first time, hooked up the N7 to my USB to transfer the files to my notebook.
Didn't make any changes.
Created a new directory on my Notebook (Win7Pro) and then opened the drive on the N7, found the TitaniumBackup directory and selected all the file (not the directory holding them).
Took about 5 mins to move the files which was about the same as the Wifi transfer.
Not errors, and all the files got there.
Not sure if that helps you...
Oh. the N7 is rooted with TWRP recovery on it but otherwise Stock.

BTW.. this morning I tried this app which is a sync app between my workstation at home and the Droid. Worked good enough I upgraded and now have a number of manual syncs setup (droid to computer)

Hi krelvinaz,
Thanks for taking the time to test that for me. I did exactly the same procedure as you. I'll play with it some more and see if it was just a bad driver install or something. Perhaps I'll try it on my laptop at work...
And thanks very much for the link... that app does look promising indeed. I really appreciate that it doesn't sync with the cloud, but with my pc. That's great.
Thanks again for your help!

Update:
Ok, well I tried to copy the same files on my work laptop, which is running XP, and without any additional drivers, and it stopped at exactly the same place, at one particular file.
I then deleted that one backup file, and tried to copy the directly again, and it worked. I then tried again on my Windows 7, 64 bit desktop and it too was successful!
I guess that file was corrupted or something.
I'm glad I figured it out, and thanks again krelvinaz.

I got my N7 today. Just plugged in USB to my computer and copied my "backup-apps" folder and my MP3 folder from my phone. Moved very fast, now I have about 150 .apk's I can install if I have recognition problems with the Play store, and 2000 songs.... using up my "16" gb fast... about time to root and add stickmount.

Nexus 7 File copying errors

Hello,
I've recently purchased my Nexus 7 and it's a great device, except for an infuriating problem.
Yesterday, I was able to copy files straight to the tablet from Windows. Today, every file hangs at 'calculating' and then proceeds to crash windows explorer and require me to pull out the usb cable.
I have tried usb debugging on/off, renaming the files to give different extensions and still nothing copies over. Only tiny files manage to, at around 600kb each.
TL;DR: I was able to copy multiple file types to my Nexus 7, now I can't copy anything bigger than a tiny photo.
Thanks!

Isn't MTP "great"? Wish Google will get it and bring back to USB Mass Storage.
We all remember how bad file-copying by ActiveSync was and that's why UMS took off as a much more robust solution.

Do you know how to fix the problem though? I can RAR my files and then copy them, but that is impractical.

I've tried using bulk file copy programs, but it says the destination is invalid.
I wonder if that is because the PC reads the Nexus as a media player, and not mass storage.
Has anyone fixed it yet?

Same problem here. WiFi Explorer works to copy the files. Not as fast but worked for me. I use the Pro Version, here's a link:
https://play.google.com/store/apps/...mNvbS5kb29ibG91LldpRmlGaWxlRXhwbG9yZXJQUk8iXQ..

Have you tried simply renaming the file extension to something different until you get the file transfered over?
I'm stuck at work or I would take a look at it myself.

Have to agree with you, MTP is hopeless. I've tried to copy a Titanium Backup folder numerous times and it never does a complete copy. How pathetic is this!
I've had to resort to using SMB with Ghost Commander and that is very slow! There must be a better way! Help!

mtp is horrific...

Same here. It copies about 70% of the files from the Titanium Backup folder in Nexus7... and then stops (as if completed). But when I check the destination folder on my PC, 30% aren`t transferred. How can we have such pathetic file transfer, in `this` day and age?

Has anyone figured this out yet? I have about 1 Gig of TB files...

Currently copying the files to a separate folder on my computer then cutting those files onto my nexus
7 works for me but is bothersome most of the time.

I just copied a 350Mb folder of files to the N7. It took 30 seconds. Then I copied it back to my desktop and it took 21 seconds. I'm stock, rooted, 4.21, usb debugging on with MTP, using the original usb3 cable plugged into a rear usb port. There must be something else going on with your devices.

I also noticed that problem. But discovered that it only show up when you start "Play music". If you have started the app and would copy something just reboot . works for me!
Nexus 7 32G, European stock rom

I have the same problems as stated before. But i also noted this: when i add a new folder anywhere on the devices memory with Astro, for example a folder with pictures and shortly after i want to copy that folder to my PC. The created folder is missing and nowhere to be found while browsing the device via usb in windows explorer. Even after rebooting the pc and nexus7. Its like the index of files doesn't get refreshed often. When i tried again a few days later, the folder appeared in explorer just fine.

Only time I have seen this problem was when I tried to copy files directly to the root of the storage directory. Try copying to an existing folder on your nexus and see if it still fails.

I shut off my Bluetooth and the problem went away.

Had greater luck with this renaming or, zipping the files. It seems if the file extension isn't recognized as being handled that it will be denied after it finishes copying.

I had the same problem two days ago ... ijust ignored it and the next day everything was working fine ... i guess try restart PC and Tab both

Try this
If you have wifi, try Airdroid! Worked for me! & when the cheapo charging port gets loose, get a "Qi" charging station. Lay your device on it and it charges right through the case, wirelessly.

That worked for me. That's really strange...

[SOLVED] This device has either stopped responding or has been disconnected.

Whenever I plug in my S4, it seems fine. Drivers are installed correctly since I rooted fine and that also means the USB is fine.
The problem arises when I try to copy any file to my phone. It plugs in, allows me to switch it between Camera (PTP) and Media Device (MTP). I have tried turning USB Debugging on and off when transferring files and on both Camera and Media Device.
When I copy a device into any folder or the main card or phone directory, it starts copying, the green bar stops and then after a second the following message comes up:
"This device has either stopped responding or has been disconnected."
It allows me to Stop copying or Skip this file... which is the only file.
Any ideas on what is causing this and what I could do to try and fix it?

Use a different cable or usb port. Something is causing the phone to stop communicating with the computer. Also, make sure you don't have any power saving features enabled that may be turning of power to the usb port in Windows.

I've tried that and it still has the same issue.

Just unrooted and performed a factory reset. My phone is totally stock and doesn't allow me to copy any files onto it.
Does anyone have any idea?

[SOLVED]
Solved this by taking out my SD card, restarting my phone, putting the SD card back in and formatting it.
You can format by going into Settings > More > Storage > (Scroll to bottom) Format SD Card

That's right, it was not easy to find... Thanks!

Effectively, you have to turn off the ENERGIE ECO on your Tablet.
another way to see that the SDCARD is not responding, is to browse inside the Folders. They seems to be empty.

i was getting the same problem,so i uninstalled the driver and then connected the mobile .
secondly i also have installed wondershare mogile go on my mobile and pc , so when i connected my mobile to pc after uninstalling the driver the mobile go pop up came up for usb installation and it asked for installing the usb driver for mobile go ,it asked me to swithonn the usb debugging ,and it installed the driver then it just worked fine .
may be it was a mobile go problem (any software) or Driver Problem but it helped so no need to format,reset or remove your card . just try this and tell wat helped.thank you.
This is a Driver Problem.

All I had to do was plug the usb cable into the usb port that i installed the device to. My PC won't read the phone right from any other USB port. I hope this helps

Im not sure if this thread is too old or not, just wanted to give my imput on the matter, so I ran into this issue just today but i had never had it before, turns out it was the file, I did everything I could think of : played around again with the USB port selective suspend feature and it wasnt that, plugged into other USP ports, want that, untill I tried copying something else and BINGO, the file got copied, so I tried with a folder full of different files like word, excell APK files etc...and they all went through fine, so next i tried a lange file a movie and it went though fine. the file in question was a nighlyROM apparently it was corrupt, or didnt download properly. So my suggestion is to check if you can copy or transfer other files.:good:

it didn't work for me

you have to fix permissions
it happened to me on my gt-n7100 (Galaxy Note II ) with android 4.4.2, you have to install TWRP (Team Win Recovery Project see how then reboot into recovery select ''advanced'' hen ''Fix Permissions'' that worked for me
you can use chmod to fix this it works too

This did it for me. I already had TWRP installed and after quickly doing this I was able to copy to/from my SD card. It also fixed the problems I was having copying/moving things from internal storage to the SD card using ES.
FYI, It also caused XPosed to break until I rebooted again.
THANKS SO MUCH!

Doing this now, thanks so much! Wonder why that happens.
Didn't work unfortunately. Other files seem to be moving over just fine. All except this 1.6GB file (checked space, that's not the issue), where I cannot send either to Internal or SD Card. Maybe it's a corrupt file?

Yeah! Exactly! I was trying to copy an unfinished movie that was still downloading in torrent. It was stuck at 98.8% and it was playing fine in my computer. Only this file was not copying in my phone. and anyways i couldn't get it to my phone because it never downloaded 100% due to lack of peers, and i could copy other files. This means MTP mode does not allow to copy corrupt or half files and there is no mass transfer mode now a days...

I was able to copy the unfinished file by mounting External SD in TWRP btw....

I've changed the file type which was a (.zip) to a (.mp3) and transferred the file. It worked.

This is the answer to this thread!

Guys this is dumb but instead of moving the file that wasn't working onto my SD card, I just moved it to my phone and it worked the first time.

Another fix - go to usb options, set to use as USB 3.0 device
Since this is the first thread that seems to come up when I googled the issue, I'll post the fix here...
though I'm on a Galaxy S5, not the S4. I'm guessing it's the same deal.
When I plugged in with USB and tried to copy a 1.2 gig file, it gave me the error message, though many large files had worked in the past.
I tried a reboot, pulling the SD card, and making sure my USB hubs didn't have the "let windows shut this off to save power" option checked.
So I tried pressing the "Connected as a media device via USB" notification when I slide the notification bar down. There are 3 options, MTP, PTP, or USB 3.0.
I changed to USB 3.0 and the file copied fine, and much faster too, about 1.5 or 2 minutes for 1.2 gigs.

This actually works.... - Raj

Unable to backup to computer

Wanted to backup internal storage to pc, which I have done several times before but doesn't seem to work at all now.
Windows 7, have adb drivers installed. Tried copying files thru adb pull, copy on twrp mode and normal mode to pc but it doesn't copy all files and folders.
Have tried installing Huawei drivers and same results.
What am I doing wrong?

Don't have another. For now used third party app to back it all up.

Which app did you use if i may ask?

I'm glad I searched a little more; I was about to start a thread but since my problem parallels yours fairly closely, I'll post here as well.
My problem has been trying to transfer nandroid backups from my twrp folder onto my PC. My drivers are functional and everything; my PC has no problem identifying my nexus, and my nexus is available (once plugged into my PC) to be opened, where I can view the files. I simply went to my twrp folder where my backups were and I tried just dragging them into a folder I had created on my desktop.
At first it just gave me a short, simple error message. So I created a couple folders within this folder, each with the name of the corresponding backups I have saved on my phone. I tried copying the files one at a time, and realized it was the very first file (boot.something.win) that was the only one unable to be transferred... The other file sections from the backup seem to have no problem.
I ran into similar issues with my type-c flash drive when I tried moving the backups onto it. It left out the first file, and changed another one of the files-- I'll try and grab some picks, or at least find out specifically what changes were made.

Boot your phone to recovery then plug it into the computer and then u can copy your TWRP Backup's to computer fine.
This is how I do it

Niiiice, yeah I will try that and see what happens. For some reason it wouldn't transfer to my type c flash drive i n recovery, but we'll see. Actually now that I think about it, I might not have ever gotten around to trying that yet, either.

File transfer not working properly

Hello guys, i've got some problem with file transfer both in pc to op5 and op5 to pc with USB, i don't know why but apparently the problem affect only medium to big files. I can transfer little files like jpg, while i have some problem with mp3, sometime work sometime not, if i insist generally work. If i try with huge files like the OTA now that i'm trying to upgrade the oxygen is not working at all. I suppose the drivers are properly installed since i can open the folders inside pc. Obviously the debug usb is active, i tryed to enable mtp in developer option (is normal that there isn't any mtp selection in the four transfer available? even if enabled mtp i still see "recharge" "file transfer" "photo transfer ptp" "midi"). I usually select file transfer, i don't even know what MIDI is and ptp is only about photos. The phone is rooted with the last official twrp and last magisk, the os is OOS 4.5.8. and is still encrypted. PC is with windows 10
edit: i can't even copy/paste those big files from a folder inside the phone to another one always in the phone.

Might be a long shot but try doing a simple restart of your phone and computer and see if that helps
