Open source SD card utilities?

alan01346
They aren't hard drives, it's a whole different process.  They work
superficially the same because that's a layer designed on.  If you go
to sdcard.org there are technical specifications and formatters for
Windows and Mac, like that's the whole world.

I've seen formatting with hard disk tools work, I've also had better
luck formatting in cameras or phones.  And many times scanning for bad
 blocks causes a hard crash of the whole computer.  I've got about 3
USB memory sticks here about 10 years old that I don't dare to scan
again.  But that in itself is odd, that for 10 years we haven't come
up with a better approach.  There are hundreds of pages of PDFs on how
they work at http://www.sdcard.org but there seem to be limitations on
how you can use that information.  Like that .org maybe should have
been a .com or .biz  Despicable.

But as we enter an era of solid state drives having proper utilities
becomes more important.  And many of us experiment with rooted phones
with Linux on SD cards, and small single board computers like the
Raspberry Pi, Beagleboard, etc. using SD cards instead of hard drives.

You have to accept this disclaimer before you can download their PDFs:
The information contained in the Simplified Specifications are
presented only as a standard specification for SD cards and SD
host/ancillary products and is provided "AS-IS" without any

SD-3C, LLC, the SD Card Association or any third parties, which may
result from there use or any portion there of. No license is granted
by implication, estoppel or otherwise under any patent or other rights
of the SD Group, SD-3C, LLC, the SD Card Association or any third
party. Nothing herein shall be construed as an obligation by the SD
Group, the SD-3C, LLC or the SD Card Association to disclose or
distribute any technical information, know-how or other confidential

Ooops, I probably broke some law by posting that. :)  I was never
interested in law school.

This has nothing to do with OpenBSD. Please keep this trash off the
list.
