Hi,
I tried building the new car by only dd'ing down the file system I dd'd off the
original working SD, leaving it at 512M. I also tried running ext2resize
expand the card to the full 2 gig. I retained the original starting cylinder
at 20. Both give the same results.
Shouldn't dd lay down a workable file system? After I dd on to the new card I
can mount it on a running linux box and traverse the file system. Everything
looks good, non corrupted.
The first partitions are non-FS where the kernel and the ram drive are stored.
Is there a way to verify those?
I can try dd'ing one of the images from the web site.
