Lost data on storage card after upgrading

Hi people I have a big issue...
...After I flashed a new ROM on my Polaris, if I browse to my storage card for unbackup my data the storage card results with no file but the it's no empty but no files are shown... Even on my computer the Memory Card is half full but there's no file inside... Using recovery data software the problem cannot be solved...
Please help me
Thank you guys

put the card in a sdcard reader and use any undelete tool for windows (this is where you find one using google) it works on sdcards just like it does on harddisks

I did It with several software and with microSD-SD adapter or microSd-USB adapter but only few useless file are displayed... it says that there's 2gb of free space but no files are displayed...

im pretty sure that leaving the sd card in while flashng isnt recommended
unless ur flashing from card and i didnt think that that was possiible

Are you formatting the sd card as fat32? by default windows will pick NTFS.. worth a look. The phone needs Fat32.

What type of MicroSD card is it?

And where did you get it from?
Is there any possibility it could be a fake? So actually a low capacity card like 2GB (or lower) pretending to be 32GB?
I used to have a program which would write to every sector on the card and prove it's actual size, very handy for checking cards from ebay, but I can't for the life of me remember what it's called!

Make sure you are not quick-formatting the card and that you have set FAT32 as the file system
If you can copy files to the card on a computer and then use them, the card is ok. Maybe try the files on a second computer to double-check.
You can also try filling up the card with data... I once bought a 4GB card and only 2GB were working :|

my SD became write protected.

Hey everyone,,
I have a 16g micro SD card and it was fine until one week ago, I used an android app for downloading torrent called uTORRENT. I started to download a movie on my mobile left it for about half hour and when I came back and checked the downloading progress I noticed that the downloading stopped and a message was shown on the downloading line that say: write to disk error.
After this my SD card became write protected and I couldn't delete or download any thing to it.
I tried several ways and programs to remove the write protection from my SD card but I couldn't.
I also cheked my SD adaptor and it was unlocked. I couldn't delete or format the memory even on my computer.
Please help me with my problem.
Thanks...

Your SD card's partition has a error..
Use MiniTool Partition Wizard Home Edition, a free software, to recover the partition after you connect it to your PC using a card reader, just to be safe. :thumbup:

Hey guys..
Thanks for your replay, I tried mini tool partition wizard and when insert my SD card and choose it to operate on it all the options become in gray color and I can't select any option. Even when my SD card partitions are shown with the rest of my computer partitions.
I also tried to format my memo from non android phone (Nokia phone)..but I couldn't because the format option don't shows when I insert the card.
Also I cant delete any thing from it and it says disk is write protected or disk is read only.

some sd cards(microsd too) have a hardware switch ont hem that write protects them, chek that, if it's locked then unlock it, and just to be sure, back up the contents to your computer and format the card in your phone, then copy the data over thru usb to ensure the computer doesn't format it(depending on your OS it might)

When it greys out, just choose 'create new partition', enter the total volume and then apply the changes...simple as that, make sure to apply every change, it should be on the left pane topmost options..let me know if you're stuck

SD card Issues

Hello every one i got this phone doogee dg310 before couples of days.
Everything is fine just one a little problem. When i put my external sd card its working. Than i try to plug phone via usb and transfer file to sd card everything is good but after 3 time connecting to pc and doing file tranfer and when i disconnect from pc i got problem. I am try to open any of files explorer and its get crash. and I am trying restart phone nothing helps. And even when i try put another card is the same. But the strange thing is that when i formating my sd card with computer and put back to phone is working fine and another card working fine until iam using file tranfer with usb 3 times. Phone andorid is kitkat 4.4.2 Maybe you know how to solve it ?

You haven’t mentioned about the storage capacity of your SD card. If your phone can support 32 GB then I suggest you to use 16 GB SD card. Try to connect your SD card with another PC and try again.

My phone spports 32 gb cards and mine card is 4 gb. Maybe its kitkat fault because i read that another people have similar problems with sd card and they are using a kitkat android.

I am trying to use sd card adapter and its the same problem and when this problem apear no sd card working until format, it even show that not sd card are turned on even internal.

I think it's crushed. Use a windows 7 based PC and connect sd card to it . Press format on the pop up menu and also press recover bad sectors . In most cases it will fix your problem . Search on internet for any mem. card repair tool and that might be help you .

Ok thanks I will try. Maybe you can recomend good tool to repair sd ?

unfortunately but its the same bug i am connect to my laptop with windows 7 and format and also scan for bad sectors and trying this with usb and after 4 time transfaring files i got the same problem

sd card write problem

hi yesterday I unexpectedly remove sd card (samsung) without unmounting from htc u11 now I can not write to it. can not format the sd card from phone as well from pc. recently I updated my htc u11 to oreo also. I dont know is it because of unexpectedly remove of sd card or oreo update because I dont remember that after oreo update I use(means download something) my sd card. If anyone have the solution thanx in advance.

How old was sd card? Could be just bad luck, and card died, happen to me. And what pc - win version you tried formated? It should let you do it whitout any problems.

If the external sd card was being written to at the time it was disconnected then it will be broken. If it wasn't then try to recover it using a pc.
The oreo update won't have changed anything with the external sd card so you can rule that out.

Sometimes, when you pull out the memory card unexpectedly (also the pen drives or even memory sticks on pc) you can lock the card. It denies to write on it. This happens due to the chip controller of the memory card. The only solution is to repair it on PC with special software tools from manufacturer or from russian/chinese/vietnamese forums which can reset that lock 'flag'. That sw contains drivers to raw access the chip controller.

thanx for your reply I use it(minitool partition) and also easeus but no one work. They show that your disk is formated but when I check in explorer data is still there. Is there any other software or method to format.

Try to search something like that: 'mass production utility', usually under this name you can find utilities to access the chips. It is time consuming to find what chip/controller your card use and find an utility which can access that chip since samsung do not publish such a tool...
You can try ChipGenius or another sw to find details, you may digg in sites like 'http://www.flashdrive-repair.com' to find a way of repair.
