When you let MS have first bite at the partitioning, GNU/Linux can only work with the scraps. And fdisk/sfdisk,and, cfdisk can display sectors [*1] - which is what Debian "sees" *not* CHS. [*1] -u,-uS,and,-Ps respectively I'm unclear as to why display/list/print partitions (in CHS) of your hard drives has any bearing on the ability of those tools to align sectors and partitions (the OP already knows it's a manual process ie, look at sectors and divide by 8). NOTE: fdisk -b 4096 /dev/whatever will deal with 4K sectors. That shouldn't be necessary with post-Squeeze releases though. You may already know this, but I found it instructive, from man fdisk:- There are several *fdisk programs around. Each has its problems and strengths. Try them in the order cfdisk, fdisk, sfdisk. Indeed, cfdisk is a beautiful program that has strict requirements on the partition tables it accepts, and produces high quality partition tables. Use it if you can. fdisk is a buggy program that does fuzzy things - usually it happens to produce reasonable results. Its single advantage is that it has some support for BSD disk labels and other non-DOS partition tables. Avoid it if you can. sfdisk is for hackers only - the user interface is terrible, but it is more correct than fdisk and more powerful than both fdisk and cfdisk. Moreover, it can be used noninteractively.) These days there also is parted. The cfdisk interface is nicer, but parted does much more: it not only resizes partitions, but also the filesystems that live in them.
