Hi Stefan,
small shot into the deep dark.... :
:)
As far as I know, you can switch fdisk to display either to
diplay units in cylinders or in sectors.
Usage:
fdisk [options] <disk> change partition table
fdisk [options] -l <disk> list partition table(s)
fdisk -s <partition> give partition size(s) in blocks
Options:
-b <size> sector size (512, 1024, 2048 or 4096)
-c[=<mode>] compatible mode: 'dos' or 'nondos' (default)
-h print this help text
-u[=<unit>] display units: 'cylinders' or 'sectors' (default)
-v print program version
-C <number> specify the number of cylinders
-H <number> specify the number of heads
-S <number> specify the number of sectors per track
When switched to display sector units it is only a matter of counting
to find the partition in question I would guess...
Good luck!
Best regards,
