It will show available space of like 100mbs, then afterwards show 16gbs or 32gbs. Not sure why you said it doesn't work that way.</p>

<p>x admin senses are tingling, couple of tidbits to cover when doing this method:</p>
<p>Make sure to change ssh host keys per PI, this makes it clear if somehow ssh access is attempted to the wrong PI. Odds are 1 to 999, but still.
Make sure the distribution used accepts dynamic MAC addresses for interfaces, ie a new MAC gets eth1 instead of old MAC’s eth0. This may not be noticed if DHCP is attempted for any interface by the distro, but certainly if assigning static addresses (but not by DHCP/MAC).</p></blockquote>

But SD cards used with Linux, including on the Pi, often contain file systems other than the ones that are part of the SD standard (which are FAT, FAT32, and exFAT). You can't create those non-FAT file systems with the official formatting software from the SD Association.<p>The fact that exFAT is used for cards larger than 32GB is the reason that many systems don't officially support SDXC cards. The licensing for SDXC is costly... but not because the SDXC license itself is costly, but because support of exFAT is mandatory and requires a non-free license from Microsoft. The license for SD (any format) is $1,000 per year, or free if you only implement SPI mode. (The SD readers on Arduino shields are SPI-only and thus avoid the cost of the license.) The hardware in the Pi (at least from the B+ on, I haven't tried the original version) actually works just fine with large SDXC cards, but it can't claim SDXC support because of the lack of an exFAT license.</p><p>If you HAVE created multiple partitions on your SD card that include non-FAT file systems, you can't reformat the card back to its full capacity with the official formatter. Sometimes the only way I've been able to do it is to use DD to write zeroes to the card (or at least the beginning of it) to wipe out the partition table. After that, you can use any software (including the official formatter) to create partitions on it normally.</p></p>

Just a few days ago I was cloning a Pi card and didn't pay attention to the drive letter (and warning!) Win32DiskImager gave me. I wrote an 8GB image onto a 1TB external drive, instantly destroying the file system already present. I'm currently running a wide variety of tools to get back what data I can. <em>With great power comes great responsibility...</em></p>

I’m not as familiar with Linux systems; as long as gparted doesn’t modify the formatting on the SD card itself, that should be fine, but if it does, using it isn’t the right solution to this problem.</p><p>Second, you really should have written this post around <a href="https://etcher.io" rel="nofollow">Etcher</a>, a modern, cross-platform solution for burning images to SD cards, rather than Win32DiskImager, a single-platform solution. If you really have to upload new disk images to a whole slew of Raspberry Pis, then you might have to do so as a team of people, each using their own equipment, rather than as a single lonely Windows user.</p></p>
