I've been rearranging a disk with gparted and it left
me with this:
Device Boot Start End Blocks Id System
/dev/sdb4 2048 976773119 488385536 5 Extended
/dev/sdb5 4096 51204095 25600000 83 Linux
/dev/sdb6 51206144 976771071 462782464 83 Linux
From my understanding, an extended partition is not a partition
that can be directly mounted. Rather it contains the other
partitions that are within it. You can see that /dev/sdb5 and
/dev/sdb6 are the logical partitions within the extended partition.
With basic partitions, you have the 4 physical partitions than can
be the first one, but you can also make an extended partition that
can the have logic partitions.
I'm not an expert on all parition options, but in being the
maintainer of the g4l project have worked with a number of things.
Hope that helps.
If I try to mount the partitions at boot time, something
gets very confused by the extended partition being /dev/sdb4
instead of /dev/sdb1.
Is there a quick way I can move the 4th primary partition entry
to the 1st primary partition entry?
Or is a hex edit and extreme care my only hope?
Or maybe it would all be simpler if I just DDed the one partition
I'm trying to keep to a file, reinitialize the disk from scratch,
and then DD it back (making sure to make the partition the identical
size).
