Copy of a partition using dd gets bigger than the original partition
I'm a linux user for some time now and most stuff I can figure out myself. Though, this one drives me crazy and I did not find any information on the internet.
I have a partition, say, , which is 128MB big. When I copy it using
, the resulting file is 134MB big. Now my problem is that I want to copy that partition as-is to a CF card, which does not work because the image is bigger than the partition on the CF card.
dd if=/dev/sda1 of=/home/me/backup_sda1.img
Why does dd create bigger files? Shouldn't it be exactly same sized like the source?
