first of all you can not mount any drive as normal user unless you are calling the mount program using 'sudo'.

but i believe you should be able to see the files atleast (not sure about modification) if the user has directory listing and reading permission set for the mount point.

eg: if you have mounted ntfs partition on /mnt/ntfs then /mnt/ntfs directory should have permission like 'rwxr-xr-x'. For this you should run 'chmod 755 /mnt/ntfs' as root user

Hope this helps,
Gopi

Remember that NFS is mounted read only.

Try using the umask mount option:

mount -t ntfs -o umask=000 /dev/device /mount_point

if you want to give this permission across everyother file on the folder (recursively) then do this:

Go to the mount point of the ntfs
eg: cd /mnt/ntfs
then run,
chmod -r 755 *

-r option will recursively set the 755 option to every other file and directories(and its contents and their contents...) use this option carefully because you are playing with another filesystem

Permissions can't be established to nfs filesystems. Use the umask=000 in your fstab options.

Satish,

Your version of Linux may not support read-write operation of NTFS partitions. Try removing the rw and seeing what happens. It could be that the mount is failing.

And just to make sure, we are talking about NTFS (a Windows NT, 2000, or XP partition) as opposed to NFS (Network File System), right?

Download and install latest NTFS driver from http://linux-ntfs.sourceforge.net/downloads.html
for your kernel.

umask is used to define what is the default permission to be set when a new directory or file is created by the user.

umask values can generally be set by the administrator in /etc/profile so that it applies to all the users who logs on to the system. Default umask values for files in Linux is 644 which means read/write for user, read only for group and others.

umask in mount command (/etc/fstab) defines what is the default permission to be used for file system where the unix style permission can not be used (eg: ntfs)

Hope this helps,

You can use a tool like ghost.

I used to copy disks using a 3rd Windows installation. Let's call this installation Windows 3

So, I put disk (40) and disk 2 (80) as slave in Windows 3. Then I use xcopy to copy all files from disk to disk.

After that, you need to use the fixboot and fixmbr command from the recovery console to boot the new disk.
