I've seen the "bs=1m" all over the map from other postings on this very subject: 1024, 4096, 8192 (even 8096)...etc. This is the first at "1m" I've seen & still wonder how this is determined or recommended. I'm using 8192 and it works okay. After doing a dd, I even did a boot test on the HD #2 and it worked slick.... still wonder about the "bs" though.... Best regards, Jack L.
