mount ntfs partition in fstab

[FcukThisGame]

I want to mount my ntfs partition on hda4 in fstab so that I can back up my windows files before I reinstall it.

I know this much...

Code: Select all

<fs>             <mountpoint>      <type>   <opts>  <dump/pass>
/dev/hda4      /mnt/windows        ntfs          ???            ?  ?

EDIT: fixed typo

This is mine. I mount it read only because I don't trust Linux updating it.

Code: Select all

/dev/hda1               /mnt/windows/win2k      ntfs    ro,uid=root,umask=000,noauto    0 0

Hi.

You can use a line as simple as

Code: Select all

/dev/hda4      /mnt/windows        ntfs          noauto      0 0

However, you're likely to want to use the uid, gid and or umask settings with an NTFS drive. Assuming that you want to give write access to user user_a and read access to group group_b, you should use

Code: Select all

/dev/hda4      /mnt/windows        ntfs          users,uid=user_a,gid=group_b,umask=750      0 0

For now, I don't need anything fancier than defaults with write permission, just need to back up my windows system that I ruined moving around to install gentoo. I'll need to copy my music and whatnot back to my NTFS partition once I reinstall windows.

Okay, only things that confuse me is the group thing, and the umask value. As far as the group thing, say I want read permission to everyone, but only write to root, then I'd need:

Code: Select all

/dev/hda4      /mnt/windows        ntfs          users,uid=root,gid=???,umask=750      0 0

It seems that you're still new to UNIX/LINUX file permissions. You define file permissions in Linux with a sequence of 3 octal numbers as XYZ. The X permissions apply to the user, the Y to the group and the Z to the world - which means everyone else. So, when you have 750 permissions it means the user can read, write and execute, the group can read and execute and everyone else can't read, write or execute.
Therefore, if you want user_a to read, write and execute, whilst everyone else can only read and execute, you should use:

Code: Select all

/dev/hda4      /mnt/windows        ntfs          users,uid=user_a,umask=755      0 0

In this case you're not setting the gid as you don't need to and are allowing the user to read, write and execute, whilst everyone else can only read and execute. The execute permission is important because on UNIX/LINUX you need it to browse through a dir. If we used umask=744, everyone else would see the contents of the root of the NTFS partition, but would be unable to browse through the disk.

yeah, I don't know enough about linux file permissions. I'll try to read up on them in the near future.

Thanks for all the help.

If you don't care about permissions you could just use

Code: Select all

/dev/hda4      /mnt/windows        ntfs          defaults      0 0

If I'm not mistaken, that will make the partition accessible only by root. I think he might prefer

Code: Select all

/dev/hda4      /mnt/windows        ntfs          users,umask=777      0 0

which will allow all users to change the data on the ntfs partition.

Using 775, data transfers still won't go, saying that it's a read-only filesystem.

saying that it's a read-only filesystem

Are you compile kernel with ntfs write support?

data transfers still won't go

Linux NTFS module does not fully support write to ntfs partition. It can not create new files, only change existing.

umask is a mask value...
So if you want a partition to be mounted with permissions set 777 you need to use umask=000.
