dcfldd: some common useful options
I already discussed some of this here some time ago, but to be more explicit…
- conv=sync,noerror
Don’t stop at errors, if there are errors, add zeros to the result so there are no «holes» left in the resulting image.
- hashwindow=0 hashlog=file.txt
Calculate hash on the fly for the whole operation to file.txt.
For all this and for optimal BS calculation, see here.
And to learn how to mount the result as a loopback device, see here.
