See the only solution known is the post directly above yours.

 

Btw . . . there is no screen shot "attached". Not that it would help or make any difference. Return it and get another.

I got solution, but I can't figure out why it works.

 

I have Scandisck Ultra 64GB microSD and becouse of W7 it format it to 1MB.

 

Solution

But your "broken" microSD card to Android device (tablet, phone etc) and it should say that you need to format card and when I formated it it started to work correctly. Size is now 64GB again and I'm happy.

 

btw. Gurus, are you using linux at all? It wasn't so hard to just try what happens if you but it on different platforms or different OS....

I found something really stupidly simple to use... I got an IOGEAR SD Card reader from amazon... Amazon IOGEAR MicroSD Reader Writer This into a WIndows 7 or Windows 8 machine showed all the missing data off the SanDisk Ultra 32 GB MicroSD HC I card... After the data was recovered I was able to use the SDFormatter to clear the unit completely...

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

Hello,

 

I have the same problem, hence I ended up to this forum, by google. Honestly, a bit surprised. I searched for the keyword '8gb sdhc read as 30.6mb', and only a few (2-3) of the hits that happened to other brands. Most of the hits are sandisk. 

 

Well, starting from the past, I've been using a sandisk compactflash (CF) for my DSLR, with zero problems. Today I bought a brand new sealed in box 8GB SDHC class 10 from a sandisk dealer, and this very same thing happened, right off the bat. That's the difference, while this problem happened to others' older card, it happened on my brand new card. I guess it can be considered a blessing, as I don't have any data yet to be lost in it. 

 

Card reader is Transcend rdp8k, also with zero problems prior to this day. Tried in both windows 7, and XP SP3, and an old blackberry, all failed.

 

Tried every possible solutions I could google in the past few hours. From Formatter 4 to regedit (found a thread that suggests editing the registry to fix locked mobile drive)

 

I'm going to ask for a replacement tomorrow, but honestly, by what I've read so far around the net, I'm kinda reluctant to exchange it to another sandisk. I still believe sandisk make a helluva CF, but for SD cards... I also got a problem with a sandisk cruzer blade 16GB thumb drive, but it belong to another section of the forum of course.

 

Just thought I'll post here to add 1 more voice to the '1%'...

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:

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

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.

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

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?
