only do this if the disks involved are absolutly identical , the harddisk
has a area on it were it stores its geometry and translation data, this
area is NOT standardized and if you overwrtie it with wrong values you
can completly kill a harddisk, that is , it will not even be formatable
or accessible by ANY tool. generaly if the disks are from the same series
(let say QUANTUM BIGFOOT 1.2 and 2.1 GB) then you should be able to disk
dump the smaller to the larger. an almost guearantied killer is disk dumping
a segate-scsi onto a maxtor-scsi, after doing this you can through it away !
so be carfull with dd....
concerning the bs= argument , the fastest blocksize is if you take the
on disk cache/8 , a too big bs will be just as slow as the default 512 bytes
