Good morning,
I have installed FreeBSD in a multiboot way on my PC but till now I can't
access my extended partition. Indeed, on my PC I have 4 primary partitions
that I organized like this:
Primary partition 1 : WinRE of windows vista
Primary partition 2 : windows Vista
Primary partition 3 : FreeBSD
Primary partition 4 that is the extended one contains:
Logical partition 1 : windows XP
Logical partition 2 : a Gnu/Linux distribution
Logical partition 3 : Data
So, the problem is that I can't access the extended partion especially the
Data one. This is my first problem.
The second one is this:
I'd like to change my profil picture (on my logging screen-I'm using KDE)
and put my personal photo for example; I have tried but kdbm inducates
that it 's impossible to do it.
NOTHING is impossible, even if KDE tells you so. :-)
These are the problems I've encountered,
so I hope I were concise. Thank you very much for being so kind and help
me to solve these problems.
The so-called Dos 'Extended Partition' begins numbering with ad(x)s5. It's
been so long since I dealt with this. Partitions 'c' is a special
designation and 'b' usually is reserved for swap. But a wild guess would be
that your logical partition 1 (windows XP) would be ad(x)s5a, [substitute
drive number for (x)] - the next would be ad(x)s5d, and ad(x)s5e (maybe
your 'Data' one?). You can manually use the mount command to test mount to
somewhere like /mnt before trying to hardcode into fstab, if indeed you even
wish to do so.
First of all, you can check partition layout using
# fdisk ad0
where I assume that ad0 is your first disk which we're
talking about. DOS extended partitions, as far as I
understood their concept, do not support the numbering
scheme used in UNIX partitioning, but continue the numbering.
According to Mike's suggestion, I think you will find
the following layout:
ad0s1 = 1st DOS primary partition - WinRE of windows vista
ad0s2 = 2nd DOS primary partition - windows Vista
ad0s3 = 3rd DOS primary partition - FreeBSD
Layout is something like this:
ad0s3a = /
ad0s3b = swap
ad0s3a = /tmp
ad0s3e = /var
ad0s3f = /usr
ad0s3g = /home
ad0s5 = 1st logical drive inside DOS extended partition
- windows XP
ad0s6 = 2nd logical drive inside DOS extended partition -
- a Gnu/Linux distribution
ad0s7 = 3rd logical drive inside DOS extended partition -
- Data
Terminology: A slice is what Windows calls a DOS primary
partition, and the separators on the slice are partitions.
Also note that a DOS primary partition is something different
from a DOS extended partition (which contains logical drives),
again not the same as partitions (in the UNIX meaning).
A partition carries a file system. For a slice in the
function of a DOS primary partition, this is implicit,
and the filesystem usually is msdosfs or ntfs. A partition
(again in the UNIX meaning) can have any file system; on
FreeBSD, it's usually UFS. As far as I know, there are
no partitions in a DOS extended partition - the logical
drives are represented by an own slice each.
The partition letter c refers to the whole slice or
the whole drive. I think it is implied since FreeBSD 5,
so /dev/ad0s7 can be used instead of /dev/ad0s7c.
Do not confuse all this confusing stuff. :-)
Try using the mount command (mount_ntfs I assume in your case)
to test-mount the drives (use -o ro for this, just to be sure).
I am not a multi-booter and do not use any Windows,
so I can't be more specific, sorry. Still I hope you can
try something given the above explainations.
