Ihave just started looking into parted and

to specify and print disk addresses.
Traditional fdisk shows clusters, sectors etc.

Parted is more user friendly program. And because of this on my own it is using MB as start/length of partition. MB is more clean for understand for just user, not for administrator.
By now Linux more frequantly occurs for desktop purposes.

Is there some advanced documentation on why parted
is using MBs and how to convert between these so that
exact disk-addresses can be known?


# /usr/local/sbin/parted /dev/hda print
Disk geometry for /dev/hda: 0.000-11513.250 megabytes
Disk label type: msdos
Minor    Start       End     Type      Filesystem  Flags
1          0.031     62.753  primary   ext3        boot
2         62.754    188.261  primary   linux-swap
3        188.262   1686.511  primary   ext3

6       3184.792   4180.979  logical   ext3
7       4181.010   4683.010  logical   ext3
8       4683.041   5185.041  logical   ext3
9       5185.072   5687.072  logical   ext3
10      5687.104   6087.128  logical   ext3
11      6087.160   6487.185  logical   ext3
12      6487.216   6785.266  logical   ext3

Partition8 ends at 5185.041 and partition 9
starts at 5185.072. What´s with the .031 MB
in between? In some cases, (between 10 and 11)
it´s 0.32MB..

Wouldn´t it be much easierand more exact to
specify sectors, clusters etc which simply
cannot be fractional?
