Hi I need to write random data to a partition before encrypting it. Suggested way is to use urandom:
#dd if=/dev/urandom of=/dev/sda2 What is the use of operand "bs" in the following case? I see the above command executed as follows sometime: #dd if=/dev/urandom of=/dev/sda2 bs=1M For the hard drive I got, should I use the following command: #dd if=/dev/urandom of=/dev/sda2 bs=4096 >From what I understand, the first command above will write data in 512 byte blocks, the second one in 1MB blocks, and the third in 4096 byte blocks. Right? I am a bit confused about the usage of this operand in this case. -- Kind regards, Yudi
