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) :

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>
<p>when i try to format my memory card: It prompts message as &quot;This Memory card is Write Protected. Please release write protect switch.&quot;, and i dont see any write protect switch in my Memory card too. please help me.</p>
<p>It should be on the left side of the SD.</p>
<p>Thank you so much I saved my 128GB Micro SD! </p>
<p>Thanks a lot :)</p>
<p>I'll try the first solution, as I've never heard about that. I read an article that suggests to check and repair bad sectors with chkdsk or third-party tools. what's your idea about that? there is the article I read: <a href="http://www.eassos.com/how-to/windows-was-unable-to-complete-the-format.php" rel="nofollow">http://www.eassos.com/how-to/windows-was-unable-to...</a></p><p>waiting for your opinion</p>
<p>Thanks, my SD card was at 800MB when it supposedly had 16GB, did the DiskPart thing and now it's back to 14.8GB. </p>
<p>Thanks! First method is great, saved most of my best SD card! (Don't know where the rest got to but 14.3GB is OK)</p>
<p>Thats a more exact measurement of how much space you have. 15/16GB is a general estimate of the amount of memory.</p>
<p>i have many attempts (refresh) but don't show any drive</p>
<p>After way too long did I stumble onto this advice. I'm very very happy I did, many thanks !! </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>more than likely thats why. It's a cheap MP3 player. Get a normal android device and it should run it fine. </p>
<p>I try this process but after deletion folders come again in sd card </p>
<p>After many failed tries, I got the solution: on my pc (Win 7 64, SD with adapter) I had to <strong>unplug and reinsert</strong> the card after the &quot;clean&quot; command in diskpart. Lets go Raspberry!</p>
<p>Same thing here. Had to reinsert after clean.</p>
<p>In my case , both the methods failed to work (this is what i conclude after observing the space being shown both in command line utility and in windows explorer (win7x64)).<br>I dont have a memory card reader so i used my samsung galaxy ace to make the card readable by the computer.</p><p>After 2 attempts , i felt REALLY BAD and HOPELESS too :(.<br>But then this happened- </p><p>I removed the card from the phone and the phone said &quot;sd card may be damaged , you might want to format it.&quot;<br>I proceeded and disconnected the usb cable and formatted it from phone's utility itself (it asked me to enter the pattern lock password)</p><p>and Here I am a happy person. :-)</p><p>I just saved myself my 16gb class 10 sandisk micro sd card without worrying about getting replacement from the company (i hate service centers and the troubles they cause).</p><p>I would really appreciate if someone can put some light on 'How it might have happened'</p><p>Note :- i use it with my raspberry pi and i dont know why the command line interface abruptly stopped recognizing commands today morning. I read in some forums that it IS LIKELY because of the power consumption of the setup ,and the only solution available is to re-install the OS. It will be really helpful if someone can put some light on this thing too.<br>Thanks :)</p>
<p>Thanks! the first one worked :)</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>nice tips.... I just made it. thanks </p>
<p>nice tips.... I just made it. thanks </p>
<p>hello thank you for putting this out there but it did not work for me any ideas </p>
Have you tried both ways?<br>What is the error that it gives you?<br>Does the computer recognize the SD card? And what OS are you using?
<p>just reformatted it in the cam now show 59 gig i think this will work </p><p>thx again </p>
<p>great news! hope this tuto helped!</p>
<p>the main problem was i used the sd card in my mobus cam before i formated it so it used up about 30 gig on a 64 gig card then i formatted it and it only formatted the unused part wich was about 34 gig now it only sees the 34 gigs </p><p>using win 7 so i have try the computer and the stand alone programs and this method with no change </p><p>thank you very much for your time to help me </p>
