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
<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>
my 32gb card got converted in 16 gb memory card. Advance procees diskpart saved my 32 gb memory card...it works!!
<p>Thanks man! you saved me from a freak-out..</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>
<p>that happened to me. my sd card was 4gb now it has changed to 1.63gb. Its annoying because that cost me &pound;20.</p>
<p>did you try Windows 7 dos command DISKPART ?</p>
<p>yeh I did everything you said in this ible</p>
<p>more than likely thats why. It's a cheap MP3 player. Get a normal android device and it should run it fine. </p>
<p>its not the mp3. I did it for my raspberry pi and the gb got smaller when I formatted it.</p>
<p>Thanks- this was a big help!</p>
<p>thanks a lot i save my 64 gb sd card..</p>
<p>Thank a bunch Saved my 16GB card</p>
<p>Awesome, had 128GHz Samsung Micro SD, could only see 32 GHz: I used the software (BTW, all its certificates are current and passng).</p><p>Thanks for the great Lil' Utility</p>
<p>I had a microSD card previous formatted as an N2A card- the original 16 gigs was down to 2 gigs of usable storage. Ran it through the app listed in the first part and restored it to its full size. Worked like a charm. Thanks!</p>
<p>Thanks Guys for sharing this but it didn't work with me. Still my 8 GB Micro SDHC use only 2.7 GB memory.</p>
<p>Try to make a disk verification to see if it has no physical problem. And then try both methods here presented.<br>Please let me know what are the results!</p>
<p>it doesn't work. now its wasted 3 4gb sd card.</p>
<p>Worked! Thanks!</p>
<p>Is this really works ?</p>
unless the card is physically damaged, yes it works
<p>Its Work !!!!!!!!!!!!! thank you!!! :) </p>
