Windows XP drive mounts as RW only.

[jap1960]

I am erunning Dual boot with a Windows XP drive /dev/sda1 and a Linux drive /dev/sdb1. How can I set up the Windows drive as read only by default?

[root@localhost /]# mount
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/sdb1 on /boot type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
/dev/sda1 on /media/disk type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096)


[root@localhost /]# df -T

I did not find any information in the fstab file.

In /etc/fstab you want to add an option ro to the line corresponding with your xp drive partition. Then you'll have something that looks like:

/dev/sda1    /media/disk    ntfs-3g   defaults,ro,nosuid,nodev,noexec 0 0

You may have other things on that line, it looks like allow_other,blksize=4096 are manually specified there (but probably do not need to be there). Changing rw to ro is the key you're looking for.

You can also install ntfs-config and then have a UI to configure your ntfs-3g type mounted partitions. This allows you to set it as readonly with the control panel found in the system menu.
