Hi Andries, Thanks for your quick answer. I CC: my reply to some potentially interested parties.

Yes, as I pointed out on http://physics.nist.gov/cuu/Units/binary.html > Slowly, old programs that use binary units are converted > to decimal ones. But there may be backwards compatibility > reasons to leave things. Here is a summary how different tools uses, k, M, G prefixes (please correct me if some entry is wrong, I made the list very quickly, some by just remembering). k M G fdisk 2^10 2^20 10^3*2^20 cfdisk 10^3 10^6 10^9 sfdisk 2^10 2^20 parted 2^10 2^20 resize_reiserfs 2^10 2^20 2^30 ntfsresize 2^10 2^20 2^30 fdisk (Windows) 2^10 2^20 resize_reiserfs seems especially unlucky since it uses binary units but recommends cfdisk that uses decimal one. If one shrinks a reiserfs and gives the same or even a bit bigger units for resizing the given partition then he has a great chance the partition table, filesystem and/or his data will be destroyed sooner or later (a new partition can start in the middle of the resized filesystem).
