Hi guys,
I am using Opensuse 11 and this is my fstab file.How should i modify it to have read/write permissions for the ntfs partitions.Also it ll be of great help if anyone can point me the use of umask,fmask and dmask...Thanks in advance..

/dev/disk/by-id/scsi-SATA_SAMSUNG_SP4002H0524J1FTB12125-part9 swap swap defaults 0 0
/dev/disk/by-id/scsi-SATA_SAMSUNG_SP4002H0524J1FTB12125-part10 / ext3 acl,user_xattr 1 1

Edit: I'm thinking from when, back in the day, ntfs-3g was read only by default (or something). The guy below me is probably right.
My fstab has the following at the top:

Code:

ab@awesomebook:~$ cat /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
etc...

I believe, to enable read-write, you simply add rw to the end of the <options> bit. So, for example:

Code:

/dev/disk/by-id/scsi-SATA_SAMSUNG_SP4002H0524J1FTB12125-part1 /windows/C ntfs-3g users,gid=users,fmask=133,dmask=022,locale=en_US.UTF-8,rw 0 0

I'm not 100% sure about this though, and i don't have any NTFS partitions (I'm on a Mac, with ext3, ext2 and hfsplus) to test it. Give it a try, though.

It's probably important to note that if read/write isn't enabled by default, there's probably a reason, however I've never had trouble in my limited experience with NTFS.

As for the *mask things, I'm not sure, but they look like 3-digit octal numbers, which makes me think of Unix permissions.

Do you want read/write permission for yourself or anyone?

Since you are a member of the group "users", and you used that for the "gid=" option, use "fmask=117,dmask=007" to allow read/write access for the "users" group.

The first thing I did in SuSE however was to add a group of the same name as my username and made that my default group.

The way I would give myself write access is:

Code:

/dev/disk/by-id/scsi-SATA_SAMSUNG_SP4002H0524J1FTB12125-part1 /windows/C ntfs-3g user,uid=knightfox,fmask=117,dmask=007,locale=en_US.UTF-8 0 0

The uid option make the user "knightfox" the owner. The fmask allows read/write access to files. The dmask needs to allow the "x" bit on directories to allow you to enter directories.
