Hi,
I was doing some experimenting with LIVE cd of SLAX. ::)
My drives were mounted as read-only.
I un-mounted them and re-mounted as
mount /dev/hda1 /mnt/hda1 -o rw
It shows it is rw but in effect its still ro. :o
How can i get around this?
-
Ensure that the drive in question is error free. You may not succeed in mounting a drive read-only if it is corrupted in any way. Set permissions as required (although if you're doing this all as root, you should be fine).
-
Those drives are my windows drive.
I was booting with the CD of Linux. It doesn't needs to be installed.
So no question of being errored. 8-)
On doing anything, it says:
Read only filesystem.
-
1. You cannot mount the CD read/write (obviously).
2. If there are errors on your hard drive, you cannot mount that read/write either.
-
There is some confusion:
I am running directly from the Linux CD. 8-)
No confusion of error on disk, as i regularly boot my system with Windows from the same disks. :)
-
Have you run scandisk on your hard drives recently?
-
Yup,
A couple of days back.
-
What error message are you seeing exactly?
-
The filesystem is mounted read-only.
Even though i remounted it as read-write, it still says read-only.
On typing mount, shows as rw but in effect is ro.
Is it possible to write on to a disc when you are running Linux directly from a CD?
-
Yes, it should be possible. There might be something I'm missing here. Have you tried asking your question over at the >Slax forum< (http://slax.linux-live.org/forum/)?
Which folder exactly are you trying to write to?
-
Good idea :D
I'll try right away.
I was simply trying to write anywhere. It included C: & D: which are the 2 partitions i have.
-
And what is the full path to those mounted partitions? Could you post the output of
mount
andcat /etc/fstab
?
-
Can't give the output as i don't have the CD right now.
It contained something like
/dev/hda1 mounted on /mnt/hda1 as ro ( mount ).
-
Made a thread is Slax forum also. ;D
-
/dev/hda1 mounted on /mnt/hda1 as ro ( mount ).
Is that a typo? If not, you'd need to edit /etc/fstab and change the ro to rw.
-
I have given you the default entry.
When i remount with -o rw then it shows rw.
-
Is the Drive NTFS ? , i think many Versions of Linux wont write to NTFS

That's what I was going to ask. If the drives are formatted in NTFS then you cannot mount them in RW, only RO. If they are in FAT then you can RW them.
-
Yup,
Its a Windows drive so NTFS. :P
But why can't it write to a NTFS partition. :-?
-
I presume you mean it's a Windows 2000 or XP drive.
NTFS support for Linux is just getting beyond the experimental stage. Check out the >Linux-NTFS project< (http://www.linux-ntfs.org/) if read-write access is important to you.
-
To be precise Windows XP.
I just wanted to play around and whatever i do, store it somewhere.
That's all.
I didn't thought it would be so complex.
I am sure there should be an easy way out.
-

Well the way things usually go, once the Linux-NTFS code comes out of beta, moves will be afoot to get it integrated into the kernel. So give it time. In the meantime, you can try it out anyway.
-
Was that a Booster to go ahead or indication to wait. :P
-
By the way is this thing possible via other unix flavours like Solaris.
Its also available on x86 architecture but not bootable via a CD though. 8-)
-
I would go ahead - why not look for a Linux distro (e.g. >Ubuntu< (http://packages.ubuntu.com/dapper/source/linux-ntfs) that includes Linux-NTFS as a package?
-
Great,
Any idea about the other Unix flavours.
-
Sorry - I missed your question before. The answer to your question is fundamentally, yes. The source code from the Linux-NTFS project may for example compile and run on Solaris. Whether significant changes would be necessary to the code I don't know - you could ask the project authors.
In any event, there are always alternative solutions to this kind of problem. Most server OSes "in the real world" should not be coexisting with other OSes as multi-boot systems. You would normally build separate systems and then connect them via NFS, FTP, Samba, etc.
-
I thought other flavours on Unix must be using diff. file systems.
May be their interaction with NTFS might be inbuilt from starting or a bit earlier.
