Hi !everyone, a few years ago i cloned a of couple hard drives u sing the dd command : dd if=/dev/sda of=/dev/sdb bs=32256

I am wondering if the same method will work with the newer laptops-uefi and 64 bits etc.

My previous cloning attempts ( successful) were all with 32 bits laptops. Today's Bios are a little bit more complicated for me anyways.

From what i read, it seems the '' bs=32256'' would have to to be something else, 64k or something for speeding the copying-cloning process.

I got a bit lost reading the said info on sourceforge i think. So if anyone has already cloned a newer system HD, would be very helpful.

These days when I clone a drive I usually use Clonezilla:

It's faster, easier and more flexible than dd IMHO.

Thank you Kilgoretrout, finally we realised that the drive was damaged anyways gparted could not even read the partition table, soooo, just replaced the disk and everything OK.
Thanks a lot.
