 I mount 2 NTFS partitions read-only every time I boot, and when I boot
 back to Windows XP (exactly once a week out of sheer nauseating
 necessity) I never get any complaints.  My filesystems seem fine.  YMMV.

When I mount an ntfs filesystem it seems to be only readable for root and not
for users. Is there any way to change this?

Hi Wim,

Add something like this to your /etc/fstab:

/dev/sdax   /winntfsdefaults,ro,user,uid=x,gid=x0   0

Adjust the x'es to your situation and you will be able to use your NTFS
partition as a normal user.

as for NTFS I have read over the past year or so that whenever you mount
an NTFS volume to run a special tool which flags the filesystem dirty,
forcing a chkdsk when the MS OS boots to try to prevent any curroption.


http://linux-ntfs.sourceforge.net/man/ntfsfix.html

that looks to be the tool though it only mentions using it when
writing to the disk. depends on how paranoid you are I suppose.

I personally wouldn't use the linux NTFS driver unless it was an
emergency.
