Re: Cloning an Entire Disk

Hi all,

Maybe not MacOS related, but I'm looking how to clone an entire
device drive drive, regardless filesystems on it,  I need to "simply"
make two hard drive equals, if have read about 'dd' command but is a
bit hard to understand the options...

in my opinion should be:

dd if=sourceDrive of=targetDrive conv=notrunc

for source and target should I use 'disk' or 'rdisk' ?

can anyone help me or know where to read further docs?

Thanks
Amedeo

Use diskutil list to determine which raw disks you want to clone. Alternately, you can use Apple's Disk Utility application, click on the disks you want one by one and then hit the info button to get the raw disk numbers.

Then I just type:

sudo dd if=/dev/rdisk0 of=/dev/rdisk1 bs=131072

The bs option is important or you will be copying the disk one sector at a time. I do this all the time and it works well.
