I would like to 'trust' the new version of fdisk but I can not risk torpedoing myself. I have 2 more drives I need to 'phase out' at some point; but they will liklely be with 1.5TB drives. The new layout you've got is meant for SSDs and drives with 4K sectors; the old layout is fine for you. > My gut tells me that i should whilst I have other drives the same size use the same paratermeters... then when i have a bigger drive that is definately not going to cause any size issues let fdisk do its magic. > > So following that premsis is there any down side to copy the partition table off another drive? I can't think of one. For backup, if I remember correctly Doug Ledford's hot-swap auto-rebuilding onto virgin drives work was going to create partition tables by copying them from existing drives (or by having the user copy the required partition table from a drive in advance).
