Question about esc2009sj.v12.img.gz

Sorry if you didn't want to copy the e-mail list. I don't answer this
sort of question privately.

Hi Jason,

I am new to Linux and trying to do the "zcat esc2009sj.v12.img.gz | dd of= /path/to/drive bs=8388608" command to my 8GB SD card. I have two partitions. The first one is Win95/FAT32 for boot and the second one is Linux ext3 (larger than 2GB). After I executed the above command to my second partition and re-inserted the SD card, the second partition didn't show on Ubuntu's File Browser (the first one was there). Could you shed some light on this? Thanks in advance.

'dd' is doing a sector-by-sector write. It is meant to be copied to
an SD card, not a partition on the SD card. It contains 4 partitions.

If I were using a BeagleBoard to execute the 'dd', it would be something like:
zcat esc2009js.v12.img.gz | dd bs=8388608 of=/dev/mmcblk0

zcat esc2009js.v12.img.gz | dd bs=8388608 of=/dev/mmcblk0p2
