It may be proprietary but it's developed by Tuxera, the same lads who created and maintain the NTFS drivers for Linux.

If it is a choice between preparing my sd cards with open partitioning tools, or running some non-auditable official tool in binary form, it is an easy choice.

I'll do the former, as I always have.

By the way, a cool quote from the agreement preceding the download page:

>3. RESTRICTIONS: You agree to NOT: (a) disassemble, reverse engineer, decompile, or otherwise attempt to derive any source code for the SDA Software from executable code;

This should be quite alarming. They insist that we format SD cards with their tool, but they don't want us to know what the tool does.

I will not be the one reversing them, but I checked it is possible to download these through tor, and recommend downloading them that way to prevent potential trouble.

The hashes for the files I obtained are:

Depending on where you live, this might have no legal effect. Some jurisdictions allow explicitly for reverse engineering & co. for different purposes (e.g. research, interoperability with other systems, etc.).

SD Cards have computers inside of them. Security conscious users will be really worried using a blob for their stuff.

Are there any open source sd card firmwares?

Would be an interesting project, I have no idea how you could reprogram them though.

[rbanffy]

Some manufacturers have proprietary undocumented APIs that allow the host to upgrade the firmware in the card, but I’m not sure every maker does, and very sure most wouldn’t bother to update their firmware unless some horrendous issue came up.

Hard drives, USB sticks and SSDs too...

[gdgghhhhh]

So what? Don't get ne wrong, tuxera is cool but this still does not make it free software.
