Allright, here is the partition from a working kobo image:
Code:
fdisk /dev/sdd
Command (m for help): p
Disk /dev/sdd: 1977 MB, 1977614336 bytes
61 heads, 62 sectors/track, 1021 cylinders, total 3862528 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
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/sdd1 19456 543744 262144+ 83 Linux
/dev/sdd2 543745 1068033 262144+ 83 Linux
/dev/sdd3 1068034 3829762 1380864+ b W95 FAT32
So I have to get the first 19455 sectors (I guess these are the sectors) with a sector-size of 512 bytes, as printed from fdisk. So I'll try:
Code:
dd if=/dev/sdd of=boot_sector_kobo.img seek=0 bs=512 count=19455
19455+0 records in
19455+0 records out
9960960 bytes (10 MB) copied, 0,664918 s, 15,0 MB/s
Allright 'ls -h' gives me a size of 9.5MB of the image ... so I'll give it a try
