Mandriva 2008 Live and write permission on External HD

Hello,
I have a Live CD of Mandriva 2008, I use the CD to save data from one HD which gives me some problems. This system has worked well, but now I start the CD that loads the operating system normally, and when I try to attack a LACIE external HD to save the data, does not make me write and control the properties of the device, I find not set the permissions of Scripture. If I try to set the permissions unable to set them. But the strange thing is that I have is something that I have already done several times, and I was always writing to HD portable ...
can some one help me??
THANK YOU

i am not practical for Mandriva, but there should be an entry point for exploring the folders as the administrator, or from terminal

Tip:
The shell command "mount-o remount, rw / mnt / <nomedellapartizione>"
makes writable file systems already 'assembled.
I had happened once looks like a usb stick but it was a problem with the file system of the stick.
I formatted and everything is back normal.

Otherwise try to open mcc the console, then click "mount points", "Configure the shared partitions dell'HD!" Configure sharing partitions dell'HD ", then choose one of three options to continue.
I do not I have never experienced so if you do it at your own risk. I will try on a disk without data

Otherwise, if you do not want to play (and with zero risk) when you need to use that disc starts konqueror (or mc or the file manager you use) from a root console and you can do what you want.
I know that is not a correct approach, but be careful if you ...

with the right mouse button, you can disable the attribute "read only"
(read only) in the "device". In this way the partition can 'be

to data loss, because 'Linux does not support all of this file system!
However, the DOS file system is FAT32, and write without problems.


Then boot , click on dell'HD you want to write (for mounting), open a console from the command on, and we write

From here forward will be mounted read / write.

A tip: if you read the files knoppix knoppix-cheatcodes.txt and KNOPPIX-FAQ-en.txt which are in many mirrors from which you can download the iso images and you will discover countless possibilities.

In my opinion the best is Puppy, allows you to immediately see all the partitions and do what you want. on the stick and is a valuable tool

Open the console from the command
on (followed by enter)
then the command above (attentive "-o" is "or less, not a minus zero).

What is the identity of the disc you see it by clicking the right button on the disk.

The mounting r / w you can also make you put the icon on the monitor, but you have to work on unmounted disk. There is also written in this text that I quoted above.

We put here
