EDIT(2), at the end
Reading some earlier post by Paul Read, I look for `dd' syntax to save
and restore my work on uSD card.
uSD card is formatted as 256MB FAT + 65MB OBERON.
Restore my work indexed as `1' may work like this,
$ dd if=OBERON1.FS of=/dev/sdc bs=1024 seek=262145
By how about saving the work first,
$ dd if=/dev/sdc of=OBERON1.FS bs=1024 skip=262145 count=???
What count should I use?
`System.Watch' may give a clue, but does not seem exact.
I could also use a fixed value of the whole 65MB Oberon partition, but
not sure if below is correct
$ dd if=/dev/sdc of=OBERON1.FS bs=1024 skip=262145
Reading `dd' manual, allows for suffixes,
$ dd if=/dev/sdc of=OBERON1.FS bs=1K skip=265K
