QUESTION
I have the following sparse file that I want to flash to an SD card:
...ANSWER
Answered 2018-Sep-21 at 16:16This difference is caused by a typo in the non-scripted invocation, which did not actually write to your memory card. There is no difference in dd
behavior between scripted and interactive invocation.
Keep in mind what a sparse file is: It's a file on a filesystem that's able to store metadata tracking which blocks have values at all, and thus for which zero blocks have never been allocated any storage on disk whatsoever.
This concept -- of a sparse file -- is specific to files. You can't have a sparse block device.
The distinction between your two lines of code is that one of them (the fast one) has a typo (mmcblkp0
instead of mmcblk0
), so it's referring to a block device name that doesn't exist. Thus, it creates a file. Files can be sparse. Thus, it creates a sparse file. Creating a sparse file is fast.
The other one, without the typo, writes to the block device. Block devices can't be sparse. Thus, it always takes the full execution time to run.
