The "bs" parameter in "dd" command.
by n00b_noob from LinuxQuestions.org on (#5AZ2W)
Hello,
When I use "bs" parameter to clone a partition or disk in "dd" command, then for recovering that partition or disk I must use "bs" parameter again? Is it mandatory?
For example:
Code:# dd if=/dev/sdc of=/home/jason/image.dd bs=1M
# dd if=/home/jason/image.dd of=/dev/sdcIs wrong?
How about vice versa?
Thank you.
