Public bug reported:
Using the card reader on my desktop my SD card's size is incorrectly
displayed, on my laptop it works fine (also above 1GB, it's not a fake
card).
The card is a 2 GB card, phys geom is H 48 S 47 C 1686
My desktop reports half the size and half the cylinder count, using
fdisk to fix it did not resolve the problem (when I enter the correct
values no matter how the size and total sector count does not get
updated.
When the card is inserted this is in my dmesg:
