After writing any image with an OS for your raspberry pi, you may have notice that no matter the size of your SD card, windows can only recognize one partition with about 60 mb. If you try to format it in the Computer menu (righ-click on it and press format), it will only free the space in that partition, to have access to the full space you have two options (only one is needed):
- SIMPLE PROCESS: step 1 - SD Formatter
- ADVANCED PROCESS: step 2 - DiskPart

Step 1: SIMPLE PROCESS: SD Formatter

1 - Download and install this software (from the SD card Organization) :
https://www.sdcard.org/downloads/formatter_4/eula_windows/SDFormatterv4.zip

2 - Open the program, and select the right drive (in my case is G:), after that just click "FORMAT"

3 - You have just formatted your SD card! CONGRATULATIONS

Step 2: ADVANCED PROCESS: DiskPart

1 - Go to the windows start button, write diskpart and press "enter"

2 - Wait a few seconds and write on this order:
- "list disk" - shows you the disks that are currently connected to the computer;
- "select disk X" - substitute x with the number of the disk
- "clean" - deletes all the data in the SD (you may have to remove and reinsert the card after this step)
- "create partition primary" - creates a partition in the sd
- "format quick" - makes a quick format

3 - You have just formatted your SD card! CONGRATULATIONS

<p>Thanks. I saved may 64 GB SD Card. </p>
<p>Thanks a bunch to the person who made this! just saved an 8gb card from the trash :D</p>
<p>Glad I could help (:</p>
<p>thanks for creating this! i have a stack of cheap sd cards that we're going to try to breathe a bit more life into them by trying this. otherwise, we might go toward making some cool accents for crafting projects.</p>
It'd not working
<p>Dang! I threw away a few micro SD cards thinking they were damaged. Thank you for posting this.</p>
<p>thank you!</p>
<p>pls help getting this as answer</p><p>DISKPART&gt; create partition primary</p><p>No usable free extent could be found. It may be that there is insufficient</p><p>free space to create a partition at the specified size and offset. Specify</p><p>different size and offset values or don't specify either to create the</p><p>maximum sized partition. It may be that the disk is partitioned using the MBR disk</p><p>partitioning format and the disk contains either 4 primary partitions, (no</p><p>more partitions may be created), or 3 primary partitions and one extended</p><p>partition, (only logical drives may be created).</p>
<p>Mine is 128gb but is showing 119 gb is that normal? Thanks.</p>
<p>Yes, that space is system reserved for the features and running of the card</p>
<p>OMG!!! THANKS, I HAD LOST MY 64GB SD XC CLASS 10 GENERATION 3 SD CARD THANKS THANKS THANKS</p>
<p>Thank you so much, I saved my San Disk Class10 16GB sd card and everything works just fine now.</p>
<p>Hi </p><p>I tried this one but while formatting its showing that please release the write protection to SD Card and i have checked the sd is not protected in any manner and i have tried with the cmd , diskpart, and regular format, and with format tools also no use please can u help me on this .</p>
<p>Sometimes on micro sd card adapters there's a physical locking switch on the outside edge of them, make sure the switch isnt set to &quot;lock&quot;.</p>
<p>THANK YOU!!!!!!</p>
<p>thank u for this software</p>
<p>oh my god.. this tool just saved me so much grief haha. I thoguht my SD card was just broken.. thank you very much!!!!</p>

<p>Hi,</p><p>I 'd like to tell a story about my 16B micro sd card :)</p><p>After installing W10 IoT and it is broken to 64MB. I tried SD Card format but not success. I then did &quot;diskpart&quot; commands and nothing was changed.</p><p>I gave a last one with <strong>micro SD to USB device</strong> - not micro SD to SD device and it worked!!! <br></p><p>Regards,</p><p>-Quang.</p>
<p>My 16gb class 10 sd card is giving errors on my Kodi on Raspberry <br>Pi. The OS suggests I reinstall. It seems it cannot save anything on the<br> disk. If I apply a new skin it goes back to the way it was. Hence <br>playback stops after some time as it cannot cache the sd card. I tried <br>to sdformat and reinstall the kodi image as I've done sincethe days of <br>xbmc but I get windows cannot format error. I used every available <br>method, some gave some cannot format error, some showed success but <br>ultimately when I checked the disk, all files are right there. Nothing <br>changes. It seems the 248mb partition created by the image is fat and <br>the rest is linux which kodi created. On a surface analysis it shows an <br>error on the MBR. I am not sure whether its physically damaged though. I<br> even tried converting the linux partition ot fat32 on diskpart. But on <br>reboot everything is back the way it was and all files intact. I've <br>noticed a few commentors have mentioned a similar problem. I tried Testdisk-7.0, which so far has given me the clearest picture and some control over the process. But its all temporary. Rescan and you find the fat32 and the linux partitions as they were. Can anybody <br>suggest a solution or maybe suggest a utility to directly write to the <br>mbr like we had in the dos days? </p><p>Thank you.</p>
<p>Thanks i restored my Raspberry Pi SD Card it worked for me it was 63 MB and now its 7GB</p>
<p>My SD 32GB card is still working, THANKS!!</p>
<p>I used the diskpart method! Worked like a charm! You are a god among men!</p>
<p>Thank You! SDFormatter was not compatible with my drive and/or disk, but the diskpart utility did the trick!</p>
<p>Worked!</p>
<p>Thanks man. Saved my 16gb card.</p>
<p>Worked Once and never again. The best thing is to place the SD card in a smart phone android, and format it from there. Works always. </p>
<p>Even the command prompt didnt work either</p>
<p>it didn't work for my SanDisk 32GB micro SD now showing as 30MB because it says that it is write protected; but it is not! Kindly profer a solution</p>
<p>Thanks. I just saved my 128GB SD card (it was formatted to 500MB)</p>
<p>This does not work for re-formatting SD cards for the raspberry pi, don't waste your time, fire up your Linux and use gparted. Problem solved...</p>
<p>It does work for formatting cards for the Pi, I have done so many times with this tutorial</p>
Never worked for me... On the other hand, Gparted always did... For all sorts of drives and any format. I guess this is solution is at the very least dependent on the system/user/drive/format since it does not ALWAYS work while Gparted ALWAYS work...
<p>You just saved my 8GB high speed card! Thank you!</p>
<p>it works guys</p>
<p>Thank you so much! It fixed my new 32 gb SD card :)</p>
<p>Thanks a bilion!</p><p>Saved my 64 GB Card :)</p>
<p>Thank you!</p>
<p>Thanks Man!</p>
<p>Thanks Man!</p>
<p>thank you, it's was very usefull !</p>
<p>Thanks i've been scouring for something like this, I tried a bunch of different software but this was almost too easy!</p>
<p>Yep, that did the trick. Thanks!</p>
<p>thanks a lot bro...i just recovered my 64gb memory card... OMG thanks a lot.. god bless you</p>
<p>hasnt worked for me either :( tried both methods....i opened a fresh microsdhc card, 16gb......windows wouldnt let me use it, insisted i format, using it in a cheap mp3 player connected with usb cable.....tried many times to get the 16gb back but no use, still only showing 3.69gb........i hate windows </p>
