What brand are these 4GB microSD cards? > Kingston Technology. To rule out virtualbox's involvment I inserted the same SD card into my BBB and checked its size as reported by Angstrom linux. root@beaglebone:~# cat /sys/block/mmcblk1/size 7626752 As you can see it reports exactly the same size. > > The magic number I've been using is 3750, which is working on > SanDisk/Kingston/Samsung 4GB > > https://github.com/RobertCNelson/omap-image-builder/blob/master/tools/setup_sdcard.sh#L1540 > > > Yes, 3750*1024*1024 is 3.932 GB, the size of the image file. Reducing this to 3750 * 3.904/3.932 or 3723 would make it fit this SD card. I would suggest reducing it slightly more, to 3700 to allow for other smaller cards. > I know that the armhf.com images are 2 GB.

I will also look at creating a script to automate the expansion process so that the result automatically fills the SD card to its full capacity, regardless of its exact size. Thanks again.
