Hi guys,
I hope this is the right section to post this issue.
Does anyone have a solution to completely erasing data from a sd card, my problem with my sd card is that i am not able to delete files from the card or add any new files. I am able to copy files from the sd card to the pc though. I have tried formating it on various computer operating systems as well as on an android system.
What i get is the format completes but after reconnecting the card to the pc or phone, all the files that were previously on the card have somehow returned and the files are not corrupt or anything because i am able to view images and play music from the sd card. Is there any method I could use or is it time to let the memory card go?
Check for Errors
Try check your SD card for errors on the computer (Mount it first).

Hi JBMorris, i have tried mounting it to the computer still no luck, I used a program called active kill disk to format it and check for errors but the program freezes on the verify and checking for errors section. I think something about the sectors not being readable so I might as well get a new sd card and thanks for the suggestion!

I think you had encrypted it with some device before.... So if you insert in that device and remove encryption...
But if you have factory reset your device and remove encryption key.. Then it will be very hard (may be impossible) to format it or change permissions

Hi killwish, that makes sense it is possible it was encrypted before as i used a different rom, so would you advice me to install the previous rom and try to format it?

Bro you have flashed new rom... And encryption key is deleted.... So now I think it is impossible to do what you want....
May be some hacker will help you... Wait if someone give you the solution
now you have only 1 option left
try replacing it from service centre for free

Oh.. Yeah it is the solution.. If your card is in warranty
You should format your SD card through CMD
To format a memory card from command prompt, follow the below procedure:
Connect the memory card to your PC through card reader.
Click on Start > Run > Type CMD and click on OK.
Assuming the letter of the memory card drive is G.
Now enter this command.
format /q /x G: and press Enter.
Note: Don't forget to replace the letter "G" with your drive letter.

Hi Snehashish, i have tried using the cmd and get an "access denied error" even though i am using cmd with administrator rights. It seems to me there's nothing i can do as i have tried formatting using different methods.
Replacing Card
Hi guys,
Thanks for all the effort, my card doesn't have warranty and I will be replacing it, what I have learned from all this is to stay clear of encryption if you not sure of what it fully entails!
Cheers Fellas!

Format my sdcard but the same files comes up after re mounting the card to pc.
+try to copy files to it and un mount frm pc but after re mounting again they are lost.
i tried to format it with
1 windows disk manager
2 Sd Card Formatter
3 CMD
4 mini tool partition
But after i re mount sdcard to pc or phn those files appear again.
P.s tried to scan with Kaspersky virus removal tool and with microsoft security essential but no virus found.
Any help?
Whats the file?!?! Maybe it is a default system file that is required for it to work!

Instead of formatting, you can try wiping the entire disk (in mini tool partition you get 5 different ways for wiping a disk). Theoretically every bit of data is gone afterwards

Sounds like they are system files that the phone automaticly copies to your sd card when it is remounted, if this is so, then it is normal, if this is not the case then try a different sd card.
If you change the File System then all files should be gone too
Boot up a Linux distro, pop in the SD card, and run "sudo dd if=/dev/zero of=/dev/((YOUR_SDCARD))" in a terminal, where ((YOUR_SDCARD)) is the name of the device file representing your SD card (make sure that you know for sure that the "of=" parameter is pointing to your SD card's device file; "sda" is often not an SD card, but is actually your first SATA hard drive).
Assuming you got the right device file as the output file, your SD card should now contain nothing but binary zeros. You can also create a text file with a witty message and write that (change the "if" parameter to "if=/path/to/your/file".
Godspeed.

this method sounds for nerdy, i might wipe my c: or d: or might brick my sd card, any other simple solution?
also thanks for your help.

try formatting it on android on the SD card , that might help
SDFormatter 3.1 View attachment sdfmt3_1.zip
Did you try FULL format not QUICK? It will remove bad sectors from SD Card.
I got a class 10 micro sdcard yesterday but when I tried to put music on it the write was like 2M/s. The computer froze in the process so I took the sdcard out before the process was finished. After I restarted my computer the computer wouldn't recognize the card anymore (no show in Computer). It wouldn't be recognized on my phone neither. It did show up on my friend's computer but if I clicked on the disk icon, it asked me to insert a card.....so I guess it might be corrupted because I got it out before the transfer was done.
So is there anyway to format the sdcard (micro sdcard)? I know there are many software that can format the sdcard but they won't work since the computer won't even detect the sdcard....
Wish I knew this as well. I have a corrupted 16GB Micro as well. Trying to format using SDFormatter tells me that it's in read-only mode or some nonsense like that.
Try this first:
http://hddguru.com/software/HDD-LLF-Low-Level-Format-Tool/
Even though windows won't say anything when it's inserted, doesn't mean it wasn't detected, just means windows couldn't mount it. Insert the sdcard and theh download and run the program, selecting the proper drive to wipe.
If that doesn't work u both could try linux. Download any live distro, I recommend slax. Burn it to a CD and boot ur computer from it with the micro sdcard inserted via adapter.
Then use this command with variation to ur specific hardware setup
dd if=/dev/zero of=/dev/???# bs=1M

SD Formatter has revived many of my cards, it will also re-partition them and format it to a single FAT32 (or FAT if its a small card) partition. All you need is the PC to see the device (such as the card reader) in device manager. Also, if you have a supported card reader (90% don't though) it can do low-level functions such as Flash NAND (of the SD Card) erase.
If it doesn't show up, I would agree to try the /dev/zero method under linux, followed by a SD Formatter wipe once the card is back to appearing in device manager.

So I understand you want you files and the card to work on the phone?
The phone supports FAT32 file system, if i'm not mistaken so you should format it to that.
Does a pc read the files on the card? Cause if so, then first copy them to you pc and after formatting back on the card.

Does the pc see the card and tell you it needs to be formatted or doesn't it even show on your pc?
If it doesn't even show up, you could be talking about a broken reader of your computer or a broken card.
If it shows up but you can''t acces, than it might be recoverable.

If your laptop's card reader is ok then check it form the device manager. Do you remember about setting any password to your MMC??
I've seen most of the PC doesn't show a password protected MMC.

Try testdisk (cgsecurity.org/wiki/TestDisk), maybe it can recover your partition table.

Hello!
My 128 GB SD card (Sandisk) had corrupted files. Every time I delete files, they appear again. I even tried to quick-format the card on Windows, but the files appear again. I also formated it without quick-format which took about 24 hours and the files were again on the card.
Is there a tool that could delete everything? A partition manager maybe?
Is there a way to find logs of what is happening exactly to that SD card? The card is 17 months old.
Thank you!

Use this tool in your PC and format sd card in FAT32 format.
@Droidriven: I deleted the partition, but was unable to create a new one. As a result, I was unable to format it again and Windows does not assign any drive letter. Thus, I was unable to use chkdsk. However, Android still recognizes the card, but I cannot make any changes to it. Even when I format it again on Android 7, it says "format succesfull!", but the old data is still there.
@ Ashwinrg: Thank you! But now Windows does not even recognize the card because of the reason I mentioned above.
Update: I manually assigned a drive letter, started CHKDSK, but it says that during "examining the map bits of the volumen" ("el mapa de bit del volumen" in Spanish) errors have been found, but the lost archives cannot be recovered.

To fix the errors
chkdsk X: /f
Where X is the SD assigned letter
To recover some deleted files or files that you couldn't move from SD card you should have used programs like : testdisk or photorec to restore them before you did a format.
@-Hope-: CHKDSK does not work because it throws some error messages.
How do I know if the card lost its abbility to write data? All I can do is read data. I don't want to recover data. I just want to fix the card.

Hello
Seems that the SD is write protected
We can try to disable the protection using diskpart tool in windows
Connect the SD card -via card reader is a recommended step- or if your laptop have a buildin reader
Open a CMD (admin)
Type diskpart then enter
Type list disk then enter
You will see a list of disks and partitions etc..
Type select disk <number of the disk> for example
select disk 2 then enter
Type then
attributes disk clear readonly and enter
Then type exit and enter
The method is explained here with pics on wikihow
http://www.wikihow.com/Disable-Write-Protection
There are some other methods you may try too

Unfortunately, I think after all of this, your card might be too corrupted to repair/reclaim. You might be chasing your own tail with this but I guess it is worth continuing to try.

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.

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.
