(I wasn't 100% sure if this belonged in the external or internal hardware forum. Feel free to move it, admins, if needed.)

Background:

I own a Samsung galaxy J3V (recently updated to Android 7.1 about a week ago) that I've owned for about a year. I got a micro Sd card soon after and have used it to transfer games over to. (I don't know the model of Sd card, I think it was an off brand and I have a picture of it below).

About a month ago the phone got factory reset from the debug screen (I won't go into why that's another story) and I restored the apps using google. 

 

Problem/Attempted solutions:

When I came to start using the SD card again it showed up as corrupted.

  • I tried formatting it using the android function a few times with no change after the action. 
  • I plugged it into my windows 10 computer with an SD card adapter, and it works on my computer. 
  • I still tried using CHKDSK to fix the drive(when I did the cmd program came back to tell me the drive had no issues), but my phone still says the card is corrupted.
  • I tried deleting all the data off the Micro Sd card using my computer- still doesn't work.
  • When I used windows to try and format it I got the "Windows was unable to complete the format". 

Still won't work on my phone

 

 

 

I don't care about the data on the Micro-SD Card at this point, I just want to be able to use it.

Do you have any possible solutions?

You could try zero wiping the card then partition and format as FAT32.

 

You can zero wipe using the diskpart command but the safest way is to use Partition Wizard. Attach the SD card and then zero wipe. Be very careful you are selecting the correct device. You do not want to zero wipe your hard drive. Use the zero quick option. All steps are virtual in Partition Wizard and do not complete unless you click Apply. This lets you back out of any mistakes.

Edit: Select Primary  and Fat32.

 

Edit Edit: If the formatting using Partition Wizard does not work then use the SD card formatter.

John,

 

          Just another tool (and free) that can be used to zero wipe a USB drive (which an SD Card is treated as) is ImageUSB.exe that comes along with MemTest86+.

 

          Their readme file describes how to use it to reclaim seemingly "lost space" on a drive that was used to put bootable MemTest86+ on.

 

          I know you've talked about using MemTest86+ for memory testing before, but I wasn't sure if you knew about this feature of the ImageUSB.exe option to do what you describe above (and with all the precautions about making sure you've chosen the drive you think you've chosen).  Another arrow in the quiver.

That's news to me. Thanks for the heads up. 

 

Edit: I think you are referring to Memtest86 and not Memtest86+ which is a different program. I downloaded the zip file from Memtest86 and that did have USBimage in the zip file.

 

The standalone version of ImageUSB can be downloaded here

I downloaded the program and opened it up. 

Bellow is two pictures, the first one looks just as the program should, though I had another drive selected to test (I didn't perform any action). But when I select the sd card (second picture) it gives me no operations possible and I can't do anything.

 

I'll take a look at what britechguy posted tomorrow when I have the time.

That is because Partition Wizard is calling the disk as bad. If Partition Wizard determines the disk is bad no operation can be performed on the disk.

 

Can you do a format on the drive using the USBimage.exe program. You would select zero USB in step 2 then write.

I had used the USB-images to zero write the card: https://s8.postimg.org/krq5p83xx/Screenshot_56_edited.jpg

It still didn't make a difference, the phone won't accept it.

I also noticed something, the Sd card still had files on it. When I deleted the files and came back a few min later they are back again.

At this point I think you'd be very safe in considering that card not only merely dead, but really most sincerely dead.

It's seeming so.

Thank you for the help anyway.

In your first image the adapter has a slide switch. Was this switch in the lock position. That would prevent the micro SD card from being written to though I think your image shows the slide in the unlocked position.

If you have a bestbuy near you then check out the 32GB micro SD card on sale. U1 for $9.99
