I've got an external USB drive that is formatted with NTFS mounted on ~/tmp. I can read it just fine, but cannot write to it, even as root (temp is a folder on the USB drive):
[root@Plugbox temp]# touch test touch: cannot touch `test': Permission denied [root@Plugbox temp]#
However, if I do a cat /proc/mounts, it looks like I do have NTFS read/write support:
[root@Plugbox temp]# grep /dev/sdb1 /proc/mounts /dev/sdb1 /root/tmp ntfs rw,relatime,uid=0,gid=100,umask=02,nls=utf8,errors=continue,mft_zone_multiplier=1 0 0 [root@Plugbox temp]#
Finally, if I go to the folder above temp, it looks like I should have plenty of permissions to write to the folder:
[root@Plugbox tmp]# ls -al total 61500764 ... drwxrwxr-x 1 root users 0 Apr 19 2010 temp ... [root@Plugbox tmp]#
What am I missing?
