Just took a look at the code and there is nothing in the history and I found the clobber from gpt, pretty much the same as it was from the first commit. Its best to change the clobber concept in gpt.c from "lets zero everything" to "lets zero main header, backup header, and create a minimum PMBR". Here minimum PMBR means leave everything as is except the partition table, which, according to UEFI spans from byte 446 to 446+(16*4) Comments? -- Joel Andres Granados Brno, Czech Republic, Red Hat. _______________________________________________ parted-devel mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/parted-devel
