Hello there,
I have recently experienced a very serious problem in my Z1 running Lollipop. I lost every single file located in my internal and external sd card, such as photos, .obb files from /android folder and everything else. The problem occured when I connected the phone to PC via MTP, and deleted the, phenomenically, empty folder tree from my internal sd card '/emulated/legacy'. After that, Windows Explorer didn't respond, and after restarting my PC, I realised that both memories were empty. I immediately disconnected my phone, run a file explorer and experienced the same results. I even rebooted to TWRP, which approved the loss of my data.
What I think that caused the problem: The deletion of the 'empty' folder tree, as it corresponds with the one located in root/storage/ of my phone, and appears to be the mount location of both internal and external sd card, and which, somehow, made it way to the insternal sd card.
What I did: I immediately removed the MicroSD card, and powered off the phone, in order to prevent the 'free' space to be overwritten. After that I created two system dumps. One of userdata.img (mmcblk0p12), and one of the whole system mmcblk0, in order to try recovering my data. Then, I installed Ubuntu and TestDisk to check the two dumps. What the program recovered were the thumbnails from the /DICM/.thumbnails folder, some images and videos from programs cache (such as ads), and even some tagged faces from pictures of the Album application, but not the pictures themselves. I also tried the same process, but by using Recuva on Windows but nothing changed. Finally, what I tried, was mounting the insternal memory as mass storage under Ubuntu, by using Go-mptfs, but I wasn't succesfull as I experienced problems during the installation and device mounting process. I didn't find any scripts for Lollipop in order to swap the two partitions on the device itself.
Is there anything else I can do?

I'm relatively new to this but up until now I've had no problems so far... So I just upgraded to the latest version of Jamal's 4.4.2, following the proper install method, clearing data and caches in CWM.
I DL'd Titanium Backup and tried to change my backup location to where I store my apps which is on my SD however upon selecting /extsdcard it says that 'this folder is not writable'. Using a file manager and attempting to access external just displays an empty folder. However, going into settings-storage shows that the SD card is mounted and displays the correct size/available space.
If I unmount then mount the card it seems to function again, I am able to access the files in a file manager. That is until I go back into Titanium Backup. Now it does something different here if I press 'DETECT!', it finds my backups and displays the correct amount and path on the external however upon selecting them it takes me to the appropriate folder and says 'This folder is not writable' and 'this folder is empty.' and Use the current folder' is greyed out. The external sd is then back to displaying nothing in the file managers again.
I've tried wiping and re-installing the ROM, but it still carries on doing the same thing. I've searched in the ROM's thread and other places and I haven't been able to come up with any solution so I'd be grateful if you could shed some light into this issue and possibly offer a potential fix?
this issue is hard.Im not a developer,but I think you need change an another firmware or change a new TF card.so you can know what's the problem.But I have a damaged TF card have the similar problem.but due to I have no important file in it ,I throw it out
hope I can help you
Howdy, couldn't find this anywhere
htc Advantage 7510 running MichyPrima ROM for years. Internal (built-in) flash drive developed one corrupt directory (the backup directory for SPB backup, natch) and got filled up, before this had plenty of room. The bad directory now appears to contain subdirectories and files with gobble-de-goop names, dates, etc. and when I try to delete any or all of them it tells me either that the file name contains illegal characters and therefor can't be deleted, or that the file is a system file and access is denied (of course the files are not write-protected). Trying to get at it and delete it while connected to an XP desktop also doesn't help because it is not recognized as an external drive, but rather as a sub-directory of a "mobile device", so I get similar errors. All other directories are fine, and most of my installed , configured software resides on this drive, along with a lot of data (I've got all that backed up to the desktop computer). I also removed some files from other directories to make some room just in case this was complicating things.
Is there some utility that will let me make an end-run around this and just delete the directory and its contents? I really don't want to format the entire drive and start over from nothing.
TIA for any advice!

Remove corrupted directory from internal flash drive checkout following link for more details.
This won't help.
As stated above, only the removable micro SD card can bee seen as a true external flash drive, not the intenal memory.
The only solution would be a Windows Mobile tool similar to Scandisk.
Now you really can't find anything to solve your problem, you can still backup all your data and hard reset your device : it should set it back clean.
I kind of concluded that myself. Just hoping someone knows of that elusive utility that will let me work on the drive as if it were a regular removable drive. I REALLY don't want to go the formatting route.
Hello, I really have no clue and hope you can help me. I even don't know how to search the problem.
Yesterday I wanted to transfer my DCIM folder with lots of photos and videos to my PC using STRG-X. I already had one DCIM folder there, so I chosen "integrate datas in this folder".
I left my PC and when I came back, I couldn't find even one picture on my PC neither on my phone.
Still, the phone says 24,17 of 24,64 GB on internal memory occupied.
Where could the files have gone? And more important, is there a way to dig, where the occupied space is and to retrieve these important files?
I am happy about any help! Thanks!
First question I have is, we're you transferring the DC I'M folder from the phone's micro SD?

Hello,
first I transferred the DCIM folder of the external micro sd which only contained 6 photos. Then the folder which got lost is the DCIM folder on internal storage.
Addon: when i open the explorer now in win 10, the windows applications crash and reload after 2 seconds. it used to open a "shortly used" tab; luckily I got a direct link on the desktop to a specific folder from where i can navigate.
It seems win 10 messed up something...

Ah ha! You're using Windows 10. I read on another forum here that another user was having issues with accessing their Note 4 via USB (MTP) while using Windows 10. I can't remember how they got around things though.

Hello,
There is a possibility that internal memory card has some kind of corruption in boot record or file system itself, which is usually fat32 file system on those media devices. It is difficult to diagnose it without physically looking at it. Our company has dealt with such data loss situations before and can attempt to recover lost images. Do you know if this phone internal memory or is it some kind of micro sd card or sd card inside of the phone?

Hi guys,
First of all, great forum and great place to learn a lot of stuff about ROM's.
I have been using the forums here for a while.
Now I have a problem with my Galaxy S 4.
Galaxy s4 :gt- i9505 (Beglium)
16Gb version
Custom Rom: optimized cm 12.1 -20160118
android 5.1.1
I had some problems playing my music files on the phone, so i connected the phone to my PC.
I deleted my MUSIC folder from my EXTERNAL card.
Then I saw There are a lot more random folders in the ROOT of my EXTERNAL card.
So I deleted the LOG files, some maps that where for AD's (like GO sms), etc.
As far as I know, I did not delete any system files or folders.
While I was in the external card, connected to the PC, I saw that my INTERNAL card had wheeeeyyy much more free space than 5 minutes before. ( normally 0.9Gb free... suddenly 5.72GB free)
So i disconnected the phone and reconnected it again.
Again same thing.
Again disconnected it and on the phone I could not find ANY FILES, NO pictures, No downloads, NOTHING
Basically, my INTERNAL and my EXTERNAL are fully wiped.
with easeUS data recovery I can see all my files and maps on the external, BUT almost all of them are corrupted.
I can not recover them/ preview them.
I have not tried the internal memory yet. It is now doing a DEEP SCAN on the EXTERNAL card, connected to my PC via a SD Card Adapter.
Any possibilities to save something from the external and the internal memory ?
Everything else works normally.
My apps work, my contacts are ok.
PC is set to show hidden and system files => nothing to see
Recycle been on the phone is empty
used some recovery apps from the play store => nothing
Many thanks in advance.
PS: I have already done a search, also on google. But could not find anything useful.
Try Deleter.
I run easeUS recovery all night on the external memory.
Got back 5% of my pictures.
Most ara corrupted.
Same story for the internal memory.
Other suggestions, tips are welcome.
If the data was deleted corrupted then it might be restored corrupted.
I suggest, from now on, to upload your photos Google's servers with the Google Photos app.
You have unlimited storage for photos up to a certain quality.
Yep, i have installed google drive.
Sh#t has happened
Will try to use some other applications for recovery.
Had some pictures i needed.
Any names of really good software to recover sd card of internal memory ?
I told you, if the data was wiped in a corrupted state, then it will be restored in a corrupted stated. Because that's how it was the last time before it was deleted. It's like a checkpoint in a game. If you die, you will revive at the checkpoint in the same state you were when you reached that checkpoint.
You could give Deleter a try. But it won't magically repair corrupted data.
Try a program called recuva: https://www.piriform.com/recuva

I won't recommend it. It failed to recover two videos from my SD card that I needed to recover for investigation purposes, even when status of these files were Excellent. After restored, these files were corrupted. The same thing went on my .OGG file that was deleted accidentally by dBpoweramp before Vorbis Comments ID Tag was applied.
Even my friend said that Recuva was unable to recover her deleted photos as it should be. Yeah, the same thing, corrupted.

I have used recuva many times but, as with any software, it really depends on the state of the data at the time the software is run.
When one is desparate to recover files, I recommend trying as many programs as possible.
Hey guys.
Today i will try many different software.
I am trying to find a way to mount my internal storage as a drive with a driveLetter, so i can scan it.
Now its mte/umte or something like that.
So it has no driveletter.
Hey guys.
I managed to retrieve some pictures from the sd card.
Software i used.

For the internal memory.
Digdeeper
And some other ones on play store.
Just search for " photo recovey".
Maybe someone can use the names, if they get in the same situation as me.
Thx for the tips guys!
Hi All,
I have an S5 SM-G900P w/6.0.1
I keep my photos on my SDCard. Recently after taking some lengthy vids, I ran out of space and it shifted over to local storage.
I backed up both external and internal DCIM/camera folders to my local machine. Then copied that backup to another backup drive.
I normally parse through the pics to make sure everything is ok before I delete the stuff from my phone, but this last batch was too big to do that, so I only skimmed through.
After thinking the copies were successful, I went ahead and deleted the pictures from my phone. I deleted via Windows 10 while looking at the folders via usb connection.
Shortly after I discovered that any of the files that were on internal storage (and some on the SD Card) were corrupted during the transfer. Their file size was inflated to approx 5.2GB each (normally around 1500KB).
I was able to quickly recover any of the corrupted files on the SD card using Piriform's Recuva. (maker of cCleaner). I mounted the SDcard directly to the PC and didn't use the phone.
However, Recuva won't browse the phones internal storage when connected via USB. Their FAQ says it can only browse and recover from physically attached drives. (no mapped drives, which I tried by using a webserv)
I tried several recovery apps on my phone itself. Disk Digger, Dumpster, etc. They didn't find anything.
AFAIK, I can't mount the internal storage on the phone as a physical drive like we used to be able to do on older phones.
At this point, I'm not sure what else I can do. It's been a day now, so the phone might have already written over the space anyway. But I'm curious if there isn't any other ways to recover those files. I hate losing pics of my kids.

Can I assume, seeing that you used "Recuva" that you are running Microsoft on your PC???
If that be the case.... will take a little time , and a good size USB Stick. and hopefully, you have a port left for USB3.0 for the S5..
That said, you could set up Ubuntu on a USB Stick (making sure when doing so, you use the whole card, so changes can be made)
Then making sure your PC can boot from a USB Stick, Power that down, Restart PC, Booting into Ubuntu. then plug in phone. Mount the it, and you should be able to find everything you are missing. (that said, I do hope you were using the Stock Camera App, and mot something else.... if so, the files, might be bad from the start, I hope this is not the case).
hope this may help you
