 |
|
i have two windowsXP NTFS partitions. One, which has my data is set to read/write access and automount. The other, my main windows boot is read-only and not automount.
my fstab:
| Code: | # NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/hdb2 /boot ext2 defaults,noatime 1 1
/dev/hdb4 / ext3 noatime 0 1
/dev/hdb3 none swap sw 0 0
/dev/cdroms/cdrom0 /mnt/cdrom auto noauto,user 0 0
#/dev/fd0 /mnt/floppy auto noauto 0 0
#WindowsXP drives:
/dev/hda1 /mnt/windows/C ntfs ro,noauto, 0 0
/dev/hdb1 /mnt/windows/D ntfs defaults,user 0 0
#USB flash disk drive:
/dev/sda1 /mnt/usbstick vfat noauto,user,exec,sync 0 0
# NOTE: The next line is critical for boot!
none /proc proc defaults 0 0
none /dev/shm tmpfs nodev,nosuid,noexec 0 0
none /proc/bus/usb usbfs defaults 0 0
|
in Gnome, i set the permissions of the D drive to Read/Write/Execute for thje group, "users".
An account, called "admin", i can read the root directory of the D but all other subdirectories are locked. admin is a part of the users group amongst others.
Shouldn't the permissions be inherited by all the subdirectories of the partition? There must be an easier way to set the permission either than doing so for each file in the drive!?!??!?!?

|
|
OK I have a dual boot system with Gentoo and Windows 2003. I can mount and read all NTFS drives just fine. However I cannot get write support to work. I have support compiled into the kernel. I can get mount to say that it is rw
| Code: |
# mount
/dev/hda3 on / type ext3 (rw,noatime)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
udev on /dev type tmpfs (rw,nosuid)
devpts on /dev/pts type devpts (rw)
shm on /dev/shm type tmpfs (rw,noexec,nosuid,nodev)
usbfs on /proc/bus/usb type usbfs (rw,devmode=0664,devgid=85)
/dev/hdc on /mnt/cdrom type iso9660 (ro,noexec,nosuid,nodev,user=methos)
/dev/hda1 on /mnt/windows type ntfs (rw,umask=0000)
/dev/sda1 on /mnt/portable type ntfs (rw)
|
I have been changeing things in fstab and trying different mount commands but whenever I try to do anything I get the following error
| Code: |
# touch /mnt/portable/test.fil
touch: cannot touch `/mnt/portable/test.fil': Read-only file system
|
I tried looking though all the things in the wiki even tried captive but it cannot find the files nessicary to enable rw support.
Does anyone have any idea's? |

NTFS write support is dangerous, even when it works. Don't do it. What is safe and easy, is to access your ext2 and ext3 partitions from Windows instead. Google for Ext2Fsd and explore2fs. The first is an ext2 filesystem driver for Windows (not sure how well it works) and the other is like Windows Explorer, only it explores your ext2 partitions. (it works fine)
Just in case you didn't already know, ext3 can be treated as ext2 for file copy purposes.

|

although they say that the kernel module supports write access to NTFS. it actually doesnt(probably need to especially hack it to work). I read this in one of the Gentoo Howto's possibly one of the above.
yes hmmm..actually its in the config info in the kernel:
| Quote: | NTFS write support NTFS_RW
This enables the partial, but safe, write support in the NTFS driver.
The only supported operation is overwriting existing files, without
changing the file length. No file or directory creation, deletion or
renaming is possible. Note only non-resident files can be written to
so you may find that some very small files (<500 bytes or so) cannot
be written to.
While we cannot guarantee that it will not damage any data, we have
so far not received a single report where the driver would have
damaged someones data so we assume it is perfectly safe to use.
Note: While write support is safe in this version (a rewrite from
scratch of the NTFS support), it should be noted that the old NTFS
write support, included in Linux 2.5.10 and before (since 1997),
is not safe.
This is currently useful with TopologiLinux. TopologiLinux is run
on top of any DOS/Microsoft Windows system without partitioning your
hard disk. Unlike other Linux distributions TopologiLinux does not
need its own partition. For more information see
<http://topologi-linux.sourceforge.net/>
