Clone a bootable hard disk the easy way
Authored by: ldm on May 17, '07 07:43:55AM

You probably should consider increasing the default block size to something larger that 1024. It should result in significant speed increases. (Keep it a power of 2 of course).

dd bs=8192 if=... of=....

Should result in 8x less system calls. Larger is better of course, so consider trying things as large as 2^16.

I guess seeing that the actual command didn't fail with any bad blocks that might be a thought...

I tried setting the block size to 65536 and it had no appreciable effect upon the transfer times.
