[F7] Not detecting NTFS partitions

[Themis]

Since i'm not to good with Linux yet.. I decided to make a dual boot with XP and Linux.

My hard disk information:
2 x 120 gb setup in raid. (240 gb)

Installation process
I installed Windows XP first, after that Linux Fedora 7.
At the installation of Windows XP i partitioned just a part of my disk.
I gave Windows 20gb and the rest was unpartitioned.
At the installation of Linux, i created 2 extra "partitions" ( Don't know how to call it in Linux ).
1 for the root ( 20gb ), 1 for the swap ( 20gb )
After everything was completed, and everything was installed..
I loaded up Windows XP and with the unused space i made a second partition for my data. ( 180gb )


Now i wouldn't care much about Linux detecting the Windows partition, but i do care about the 180gb.
I've read about why this distribution doesn't detect it automatically, so that isn't what i want to know.
But what i do want to know is how to set it up and make it all work.

I'm still a beginner with Linux, so take it easy on me!
I've used Google, and i found some information about this: http://wiki.linux-ntfs.org/doku.php
But this isn't just only for Fedora. And to be honest, since i don't know what I'm doing I'm afraid to f*ck it all up.

for starters, swap and root don't need 20gigs, anything above 1gig for swapis a waste of hdspace.
and try reading this, and if you have any doubts post them back ok?
fc7 ntfs (http://www.mjmwired.net/resources/mjm-fedora-f7.html#ntfs)

I remember reading that if you want to use things like saw suspend (i.e. hibernation, "suspend to disk") you should have enough space in your swap to fit your entire physical memory + your typical swap usage.

So swap should be memory dependent, but agreed 20GB is a total waste.

I think 20Gb is not too bad for a "/" root partition if you don't intend to have any other partitions (ie. /home). However I think you'll find that it takes some experience with Linux (installing and upgrading and *usage*) before you find a suitable partition scheme for yourself.

I had a very little Linux experience before this with Mandriva, but the installation of both operation systems i did myself, asked no questions to anyone, just did what i thought was needed.

I'll keep it in mind for the next installation i do, but there are some things i still need to know about the ntfs.

[root@localhost Johan]# sudo mount /dev/sda1 /media/c_drive -t ntfs-3g -rw -o umask=0000
Error opening partition device: No such device or address
Failed to startup volume: No such device or address
Failed to mount '/dev/sda1': No such device or address
You seem to have a SoftRAID/FakeRAID hardware and must use an activated,
different device under /dev/mapper/, (e.g. /dev/mapper/nvidia_eahaabcc1)
to mount NTFS. Please see the 'dmraid' documentation for help.

I think you know enough.

I, uhh still need a bit of help with this, it almost was on the second page, which anyone barely reads.
So you can see this as a bumb!

"Failed to mount '/dev/sda1': No such device or address"
Are you sure you picked the correct device to mount?

How is your NTFS partitioning setup?
What is the output of 'fdisk /dev/sda -l' ?

Otherwise did you try looking on the internet for what that message means?

The ntfs-3g output had the answer above. Here it is again:

What is the output of 'fdisk /dev/sda -l' ?

fdisk is less useful every day because more and more volumes must be mounted somewhere what fdisk doesn't list, e.g. under /dev/mapper, supposed they are activated already.

Thanks for the update. Has anyone written a formal documentation or some good examples?

I would be very much interested. Other threads on possible related problems were unclear or incomplete.
