Hi Michael, Thanks for the info; lets see if I can answer some of the questions:
To clone a card the challenge is that any 2 cards aren't necessarily the same length - any 2 8GB cards might vary depending on the cards ideas of how much space to leave for bad sectors, how they organise thing and the general phase of the moon. If you have really absolutely identical cards then cloning them using the whole device (/dev/mmcblk0) should work, but if you want to clone so you could stuff it onto another one then the only safe way is to make sure the partition is a bit smaller than the whole disk (to allow for the next card to be a bit smaller), then when you partition the new card make the partition on the new one exactly the same size and then clone the partition. Now, to your errors: 1) well it shouldn't hard hang 2) and if the card really is large enough for your image then it shouldn't run out of space - check that the size shown in /proc/partitions matches the size of your file. 3) You shouldn't get that task hung error 4) If you're getting any I/O error's prior to ejecting the card then the bit to include in this log is the set of stuff just before the first I/O error. Errors after ejecting the card are well, expected! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/975305 Title: dd writing to an SDHC /dev/mmcblk0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/975305/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
