Yep. If you look inside an SD to USB adapter, there's the 2nd chip.
It takes care of translating the SD cards 8 pins to the USB 4 pins, as
well as 3.3v to 5v translation.

Sorry about the screwup. I was playing with micro-SD while hacking a
Droid phone, and somehow decided that it was an SD card.

More than you ever wanted to know about SD cards:

Official SD card formatter. Might as well try the real thing:

Thanks for the pointer Jeff. I tried it, and it does correctly identify
the device, size and drive letter-wise. However, when you ask it to do a
format, it starts, then hums and hahs about it for another five minutes,
before finally declaring that the device is write protected, and that I
should turn off the write protect switch ...

Oh well ... :-\

I've got a SanDisk 8Gb SDHC card here that does exactly the same thing with
that formatter.
It is brand new and failed the first time my girlfriend put it in her
camera.

Neither camera or laptops will format it, though windows does actually show
the camera's filesystem, with one jpg and two movies on it, but you can't
open them.


Cuh.
