How to repair micro sd 16gb card? It shows 31mb

Hi,

This worked for me: put the micro-sd card into any Android device and use native format utility.

Hey, have repaired your Micro SD card and also get your desired Samsung phone data back? After experiencing similar phone memory card format data loss troubles several times, I know the first thing you are supposed to do is to stop using this formatted card and then see whether the lost stuffs can be restored with card format recovery software.

Here is guide for you:

Recover photos from formatted SD card

I had a problem with a 64 GB SDXC card yesterday. It’s capacity showed as “1 MB” on all devices and showed both “NO SD” and “SD ERR” in my GoPro Hero 3+ Black (v3.0.0). I tried formatting using a computer (Win 8) with diskpart.exe as well as other reformat tools. No luck. I then plugged it back into my GoPro and tried reformatting it on there (settings>erase>erase all/format). This seemed to fix the problem and it now recognized it as a 64GB card on my devices and functions normally. 

That said, there seems to be no way to recover any data on the card. This needs to be addressed by SanDisk however I have not yet gone through the hassle of contacting them. 

This problem is when you protect you SD card with password, and try to format before without uncript using you default password, and then SD card only shows this 31mb. Maybe any software can format without decript, but how, and what program can do that?

HERE IS THE ANSWER! THE STUGGLE IS OVER.

AND YES I HAVE TESTED IT. IT WORKS!!!

You can use DISKPART in Windows, or the equivalent fdisk command under Linux/Mac.


DISKPART (Windows)

Start a command prompt, and start the DISKPART console. List all of your disks by typing LIST DISK, then select the proper disk with SELECT DISK # (where # is the SD card). You can then type CLEAN to clear the partition table on the card, effectively blanking it. MAKE SURE YOU SELECTED THE PROPER DISK BEFORE RUNNING THE CLEAN COMMAND!

To create a primary partition to reuse the space on the card, type CREATE PARTITION PRIMARY. This will then reallocate the previously “cleaned” space.

To format, type FORMAT FS=FAT32 QUICK, and finally, to reassign a drive letter, type ASSIGN.

If you’re unable to determine the proper disk, remove the SD card, run DISKPART and LIST DISK, and then re-run it with the SD card inserted. The SD card is just the disk that has been added.

Note that the above commands are not case sensitive; I used caps to match the convention DISKPART displays.


FDISK / CFDISK (Linux/Mac)

In a terminal, start fdisk /dev/sdx where /dev/sdx is your SD card device (may depend on the Linux distro you’re using, see below). You can then delete all existing partitions on the device by typing d, and then adding a single new partition & format it. You an also just type n to create a new partition table, and start laying everything out.

cfdisk is also another viable tool, which is basically fdisk with a greatly improved user interface. In both cases, once the drive is formatted, you will lastly need to mount it.

If you’re unable to determine the proper device, remove the SD card, run fdisk -l, and then re-run it with the SD card inserted. The SD card is just the device that has been added.

I found a solution that worked easily for me.

My SanDisk 2Gb was offering me only 34Mb and I didn’t even formatted it.

So I tried formatting and nothing worked.

I found this How-to Geek answer and followed the steps and I recovered the whole 2Gb.

Formatted it as NTFS afterward because it is more up to date and you won’t get the “Need to format” message anymore.

At least, I didn’t get it after format.

So here is the address :

http://www.howtogeek.com/170794/ask-htg-how-can-i-reclaim-the-full-capacity-of-an-sd-card/

I made myself a copy of the steps in case it happen again and

I added the lines 

"Redo the List disk again and you will see an asterix aside (on the left) of the disk 1 and that tells you chose the right disk."

Right after 

Whatever commands you execute after this point will only make changes to the selected disk; now would be a good time to double check you’ve selected the right disk just to be extra safe.

Because it would be unfortunate to wipe out all my C:\ drive instead of the SD Card.

Make sure you see the little asterix aside the SD Card Disk number ID and then do a Clean command.

After, you format and there you go.

Hey Guys!  I had an 8GB that only shows 1.8GB.  I had used it in a garmin GPS to update the GPS unit.  Well it went in with 8GB and came out with only 1.8GB. The garmin can only use 2GB, so it partitioned the chip for 2GB.  But I found this really brilliant video that shows how to re-partition the chip and it worked like a champ.  here is the youtube web site.

good luck, but be careful what you are working with, cuz you could mess up your main computer drive if you’re not.

I am having the same issue here with 2 Micro SD cards and the other 2 don’t show up at all in anything. 

Big ups to you bro, I created an account just to give you some kudos. I tried going through the cmd prompt and diskpart then clean then create primary partition. And none of it worked, this is brilliant, thank you!

I’m almost certain it was because of password protection, it was in my orange pi running retrorangepi but I have no other Linux devices to set up a correctly positioned drive. Dunno why Android works, but it does
