File system error? - Nexus 7 Q&A, Help & Troubleshooting

I was copying a file from my computer to my nexus 7 and it didn't seem to be copying after a while so I stupidly unplugged it.
Now a ton of folders are missing from my main storage. Seems like file system errors but not sure what tools to attempt to fix it with.
Thanks for any help.
Decided to just backup and do a wipe and reset of my tablet.

Have you tried looking at them with ADB?

shows the same folders that my N7 mounted as a media device and File Explorer app shows. A lot of stuff is missing.

I really wish I could fix my tablet :crying:
I'm scared to use it until I fix it.
Here's the folders it shows now, there were about 15 or so folders before, such as data, screenshots, videos, documents, downloads, and many others.
My tablet is rooted with clockwork mod recovery installed with motley anykernel nexus7 1.1.1 GPU 484 build 219

I've done the same stupid thing to a flash drive a couple times and windows check disk was able to repair it -_- I don't know what the equivalent tool for android would be though.
If I could only mount it to my computer as a mass storage device instead of a MTP device but N7 only gives you a choice between MTP and PTP
also hidden files makes no difference

Flash won't rewrite

The flash storage on my nexus 7 seems to not be rewriting like it should, when i pull it up in Windows i can see and delete things from the MTP interface. But when i use a file manager (OI File Manager) i can see the files once more and get an error when i attempt to delete them. i have done the Backup & Reset option within android after attempting a full data reset in ClockworkMod Recovery. At this point i am scratching my head. i am downloading another rom and will flash and post what i get from that.
Anyone else have this strange issue?
I've noticed this as well, anything I delete with ES File Explorer still shows up when it's plugged into my macbook but isn't actually accessible, I'm still on the stock ROM.

Nope, not even rooted, not really a big issue since I mostly use airdroid to transfer files but it would be nice to fix it.

The next thing i am going to do is return to stock, a complete re-flash to see if it empties the storage, I am posting all my theories so that anyone with the same issue could easily follow.
Success!
Using Wugfish Nexus Toolkit, my problem appears to have been solved. whether it is a perminant fix or not has yet to be known.

Apps can't see media files

I don't know why but all my media apps cannot see the files but when I browse the file tree I can play them from there... this started happening about 2 weeks ago... I have tried different ROMs, reloading the files from my computer and fixing permissions but it still is broken...
Any advice would be great...
Apps in question are Google music, n7 player, win amp...

Check for a file called .nomedia I think it is, and if it exists, delete it

What folder would I look for this file ...

I think the. Nomedia files is not the problem... cause i remove it already... n it didn't work....
U have to transfer the data using on windows 7 or 8...
they'r support it... files u'r copying from usb, from cloud will not show up on gallery.... it happens to me.. but, i can play it tough.... try this apps... wifi file transfer....
Upload the data depend on the files type... it should be work....

So I decided to crack flash some ROMs and for some reason after flashing miui my files are back and visible... I flashed back to paranoid android and it works again... not sure why but thats how I got it to work
Sent from my Nexus 7 using Tapatalk 2
I had the same problem the other day... not with the N7 but with another android phone. It turns out after a google search that somebody said the recent ROM Manager update sticks a .nomedia file at the root level of the sd card causing nothing to be found. Low and behold, there was a .nomedia file at the root level. So I deleted it, but it seemed not to work. I gave up and decided to back up the sd card and wipe it... but after several minutes of copying files over usb to the pc, the media files appeared again after I unplugged the phone. I guess it just takes a bit of time.
If it is in fact the fault of ROM Manager, whatever possessed the developer to put a .nomedia file at the root level of the sd card is beyond me. Nevertheless, I've uninstalled it - not because of this, but because I rarely ever use it.

Backing up files( starting to get annoying)

Had my Nexus 7 for a month or more now and decided to start rooting it, but problem is that I'm trying to copy all my files to my Mac Book pro, its copying then stops, barely copied any files with android transfer so I dual booted to windows 7 and same thing, I have more than 10 gb of files on my Nexus 7 but only see 6 gb worth of the copied files. All the folders are there but it seems like it doesn't have all the contents inside. Anyone having similar problems, I rather abandon rooting then deleting my files. But there are apps that's necessary for me that requires root. Thanks

I think there is a max file size issue with stock android on nexus.. Try to copy the largest file by itself and see what happens . Also get a log file of the process to see where its giving errors or stopping and why. This can help you get better response from on here other then people guessing..
If you do not know how to get the log files. You should google it. As running custom roms its a Must to know as well as many other terminal commands..
Good Luck

Make sure the Nexus isn't going to sleep during copy. I found that if I had the device plugged in and it went to sleep and I tried to go back to view the folders, I had to wake the Nexus up again otherwise it wouldn't detect anything on the internal storage.

[Q] USB Storage is acting weird

When I connect my Nexus 4 to my PC things get a little weird. I've attached an image to show my problem. Some folders (for instance TitaniumBackup) show up as 0kb files. Also, some files that I deleted like the LTEhybrid zip still show up in explorer. Trying to delete the file does nothing in explorer, likely because it doesn't exist. Sometimes I can't copy files to or from my phone. I'll get an error that my phone is no longer responding or the copy dialog box will simply disappear. I'm hoping this issue can be resolved without restoring to factory settings.
I should note that changing to PTP seems to function better, but I can only access DCIM and Pictures.
Debugging on or off makes no difference. I'm running stock rom 4.3 rooted, although I've had this problem for as long as I can remember. The file system works perfectly fine on any app on my nexus 4. Does anyone have any ideas as to what is wrong or how it can be fixed?
Thanks.
I've not found a way to fix as of yet. It's a bug in mtp.
A quick reboot will force it to update properly then you can get your files. But the bug will happen again

Rebooting does not help. I've tried using a program named MyPhoneExplorer which seems to work well. I can copy things to and from my phone's storage and everything is displayed accurately.
Would it be safe to assume it's a problem with windows and not with my nexus?

Can't download anything... Also can't move or delete files with root explorer

I am having a problem downloading anything from Google chrome app. It starts off getting the download setup and then automatically goes to queued and continues to stay that way....
Also having problems with downloading the latest chrome update in the Google play store. It just continually just sits in the downloading state and never changes.
I also can't remove or delete files with root explorer. Says process was failed no matter what I do.
I am running a clean install of pure nexus 12-1 build with, pure nexus gapps, and kyro 5.8 kernel.

check unknown sources in security, clear google play services cache, set root explorer to read/write (r/w instead of r/o or read only). These should have been done upon installing the rom and root explorer but can't hurt to check redundancies nonetheless

All of these things were taken care of before I put together the post. I checked the unknown sources, wiped cache for google play services, also set to R/W for root explorer. I have also tried to clear cache on google play store and tried a older version. Went to into recovery and wiped dalvik and cache, then rebooted and no change. Also wiped everything but internal storage and reinstalled everything with no change. Thanks for looking into the post though! Any other help would be greatly appreciated!
If you have any backups, I'd suggest you restore them
I just tried a clean install of Pure Nexus rom 12-1 and Pure Nexus gapps with no other apps installed or changes to settings and its still the same results
I have also came to find out that I cant move files around when connected to a PC on MTP mode. BUT I did find that I can move and delete files all I want in recovery TWRP. It seems to be only a problem when booted up and running that wont allow anything. But when in recovery its doesn't? Any insight would be GREATLY Appreciated!
Now I have flashed everything back to the latest stock img but did not relock and unlock the bootloader again. Followed the instructions in section 9 of this guide http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928. Also did not wipe internal storage. Then continued to boot the phone with STILL the exact same problems!!!! What is going on here?!!!
It also force closes my camera when trying to save the picture.. But it will take the photo..... My bluetooth will not connect to my huawei watch.. any ideas at all? anyone!?

Yes...when you returned to stock, did you wipe your entire internal memory, or just flash the stock rom?

Sounds like you need to format the internal storage. Backup everything you want via an otg usb in twrp the format internal storage and c if that fixes it...

I did not wipe internal storage. I didnt think that was the issue. I flashed everything back to stock but did not lock the bootloader again. What is otg usb? I have already backed up my devices files on my computer.
So do u guys think I just need to format my internal storage, reboot and then just reinstall my internal storage via usb when rebooted?

Yes, but do not just throw your files back onto your device.
Do as indicated below, or as close to this as possible...this assumes that you've properly backed up your files, and ready to nuke...
1. Either dive into TWRP, or via fastboot (or a toolkit like Wugfresh), wipe your internal memory
2. Factory reset your device
3. Install whatever rom you want
4. Only copy the contents of your folders, NOT the folders themselves.
Item 4 is critical, inasmuch as your device automatically recreates folders on your phone, including downloads, etc.
The folder labeled camera inside the folder labeled "DCIM" only gets created after you've taken a photo...so you can see why just throwing folders and files back to your phone creates a hot mess.
One drawback of using TWRP is that when restoring files from your computer to your device, they'll have a date of 1970 or something similar...the upside is, of course, is convenience and speed.
Good luck!

You have an alternative...rename the folders on your computer to something like "downloads2" or something similar, and just drag the entire folder.
But yes, do not, under any circumstances, copy the folder of the same name.

I'm a weird one and always eipe my internal storage. When I came from stock to this I doenloaded all the files I needed including the latest vender, erased all partitions under advanced wipe besides internal, then flashed the img's and zips "Purenexus and gapps" then formatted internal. Been doing it this way for years and have yet to ever have a bad flash or problems. Cant say the same for people trying to keep their stuff. I always say if it is important, back it up. I always put my pictures on the pc before I flash roms. But that's just me. I don't want files left from the previous OS because i've just seen problems arise because of it.
great job mic and jrb...
