Package: util-linux Version: 2.25.2-6 Severity: normal
I have an 8GB USB flash drive containing the attached Master Boot Record (MBR).
On this freshly-setup Debian 8.3 system I manually constructed the partition layout and believe it to have the following attributes:
Partition #4 in MBR
~7900 Cylinders
64 Heads, or Tracks
32 Sectors
having created the partition layout using fdisk (possibly an older
version tho).
(The fob's actual use is as a full Deb server, with sda1 being an extended partition containing 2 logical ext3 partitions and it boots up and runs all fine - the attached MBR that lacks sda1 is a 'simplest case' example of the problem.)
So now when I examine the attached MBR in fdisk via the cmds:{ printf "u \n x \n p \n r \n q \n" | fdisk Sample64h32sMBR.mbr; } | grep -E "^(Geometry|Device|Sample64h)"
the 3 lines output are:
Geometry: 64 heads, 32 sectors/track, 0 cylinders
Device Boot Start End Cylinders Id Type Start-C/H/S
End-C/H/S Attrs
Sample64h32sMBR.mbr4 * 1 412 412 6 FAT16 1/1/0
411/32/63 80
The first and second lines are as expected, however the 3rd line SHOULD have the End geometry as:
411/63/32
instead of the indicated:
411/32/63
(The problem also manifests when I don't invoke the 'u'nits command - I
only invoked the 'u' command to cause fdisk to output the "Geometry"
line, making the problem readily illustrated.)
Of note: I believe the problem also affects the Start-geometry fields as well.
I'd plead that the problem be corrected by way of reversing the fields of numerals that are output as the Hd & Sec fields, and not by way of simply reversing the columnar headers, since Cyl/Sec/Hd display would be both a minor mind bend to do calculations and verifications of data upon, and also in conflict with what it seems to be the widespread convention of ordering the fields in a MostSignificant-to-LeastSignificant, Left-to-Right arrangement. (At least for English-speakers :)
In any case thanks for considering the bug, and your work on open source code!
