How do I clone a 4Gb SDHC Card to another 4Gb SDHC Card
I have 2 identical SanDisk Ultra SDHC Cards, 4Gb.
I have been using one SDHC card to boot a notebook and run Xubuntu off it.
It contains the boot, root and a little swap space.
The second SDHC is a brand new unused card.
When I insert these into my Ubuntu desktop, they show up as:
I want to make an *EXACT* copy of the first SDHC card onto the second SDHC card.
What should I type on the Ubuntu command line to do this type of cloning?
That did it.
Having a swap partition on an SD card is not a good idea. Also, you want to add the "noatime" mount option for the partitions. An SD card has a limited number of writes. If you use "noatime", the access times aren't recorded on the filesystem for every read. A swap partition may be written to at a high frequency. This could wear out the card prematurely.
