So, given the fdisk output, Disk /dev/sdb: 111.8 GiB, 120034124288 bytes, 234441649 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x0000c89d Device Boot Start End Sectors Size Id Type /dev/sdb1 2048 1026047 1024000 500M 83 Linux /dev/sdb2 1026048 2074623 1048576 512M 82 Linux swap / Solaris /dev/sdb3 2074624 6268927 4194304 2G 83 Linux would count=6268927 ? oh, and this way, I can lay the image down on any drive. Even a mSD card (as that is the actual boot device, but the Cubie uboot (and linksprite) can run almost completely from a sata drive). thanks
