Change permissions for /mnt/win_c

[chocobanana]

Greetings

 

I wanted to change permissions for my mounted windows partitions, but I haven't so far been successful with it.

 

When the partitions are unmounted, I can change the permissions as root without problems.

 

However, when they are mounted and I try to modify them, even as root, it says I don't have privileges.

 

I also tryed to change its permissions via the mandrake control center, but without any luck.

 

Can someboy help? I'm using Mandrake 10.1 oe

 

Thanks

how about showing us your /etc/fstab file? ;)

here it is:

 

/dev/hda6 / ext3 defaults 1 1

/dev/hdb2 /home reiserfs notail 1 2

/dev/hdc /mnt/cdrom auto umask=0,user,iocharset=iso8859-15,codepage=850,noauto,ro,exec,users 0 0

/dev/hdd /mnt/cdrom2 auto umask=0,user,iocharset=iso8859-15,codepage=850,noauto,ro,exec,users 0 0

none /mnt/floppy supermount dev=/dev/fd0,fs=ext2:vfat,--,umask=0,iocharset=iso8859-15,sync,codepage=850 0 0

/dev/hda1 /mnt/win_c ntfs umask=0,nls=iso8859-15,ro 0 0

none /proc proc defaults 0 0

/dev/hda8 /tmp reiserfs notail 1 2

/dev/hda7 /usr ext3 defaults 1 2

/dev/hda10 /var ext3 defaults 1 2

/dev/hda9 swap swap defaults 0 0

 

Thanks for your interest

You can edit this file to make win_c writeable, but I would advise against it.

 

NTFS is not supported by Linux very well - it can read fine, but writing is very risky.

 

And remember, if you mess it up, you cannot reinstall Windows without reinstalling Linux too - Windows will overwrite your boot-loader.

 

You seem to have plenty of partitions - have you room for one more? If so, I suggest squeezing in another partition, making it FAT32 which is fully functional for both OSes.

 

I've always done my partitioning prior to installing Mandrake, so I can't tell you the best way to go about this. Maybe one of our resident HD experts can step in?

In other words DONT make your NTFS/C partition writeable.

A linux NTFS write *will* destroy it.

i second that. if those were vfat partitions, the whole thing would be different. the best solution would be to create a vfat partition for accessing files from both linux and winxp

Hi

 

Thanks for all the replyies

 

I think you are all misunderstanding what I want do

 

I don't want to change permissions for the files inside the ntfs partition, and neither do want to modify its contents.

 

I simply want to restrict the access (for viewing and reading at least) to that partition to some of the users of this machine. For example, user A and D (or group 1) could view and read its contents and user B, C and E (group 2) couldn't do a thing with it.

 

If anybody can give me a hint at this I would be grateful

 

Thanks

I'm not sure how safe this is, but the basic would be

 

chown root:group1 /mnt/win_c (give ownership to group1)

chmod g+r /mnt/win_c (allow group1 to read)
