Some system details:-
Dell Inspiron N-4010 OS: Ubuntu 12.04 and Windows 7 Home Basic RAM: 2GB Processor: Intel Core i3

A few days ago, I decided to shift my Dropbox and .thunderbird folder to my NTFS (non-Windows) partition
(/dev/sda5/). Hence, using
PySDM, I activated the auto mount option. But after a day or two, I started getting the following message during boot:-
Mounting failed for the partition /media/New\ Volume. Press S to skip mounting or M to manual mounting.
Then I tried disabling the auto mount using PySDM but saw that the partition had become read-only. After reading about the problem online, I realized that modification of the
fstab file was a way to alleviate the problem. Using this very helpful tutorial (http://www.tuxfiles.org/linuxhelp/fstab.html), I modified
fstab which now looks like this
# /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda6 during installation UUID=c66c1971-3833-4c46-bf91-052554bc9b79 / ext4 errors=remount-ro 0 1 # /boot was on /dev/sda7 during installation UUID=a0a94302-df4a-4334-b31b-35fbd3905da4 /boot ext4 defaults 0 2 # /home was on /dev/sda9 during installation UUID=a65aa0c6-d155-48d8-aef8-cfed1dc9c215 /home ext4 defaults 0 2 # swap was on /dev/sda8 during installation UUID=144c77f0-ad85-44a3-9110-1f3385fb4940 none swap sw 0 0 # New Volume was on /dev/sda5 during installation UUID=EA42F6C442F69513 /media/New\040Volume ntfs-3g defaults,rw,noauto,user,sync 0 0
But then I found out that since this is a
NTFS partition, I required
ntfs-3g to mount it and it seemed that
PySDM had modified/played around with it. A bit more reading told me that rebuilding
ntfs-3g was the best option and I did that using this Ubuntu Forums post (http://ubuntuforums.org/showthread.php?t=1661757).
Now I begin with my two problem. Firstly, I see two icons for the same partition in Nautilus as can be seen here.
When I click on the first 'New Volume', I get the following error
Error mounting: mount exited with exit code 1: helper failed with: Error opening '/dev/sda5': Permission denied Failed to mount '/dev/sda5': Permission denied Please check '/dev/sda5' and the ntfs-3g binary permissions, and the mounting user ID. More explanation is provided at http://tuxera.com/community/ntfs-3g-faq/#unprivileged
When I click on the second 'New Volume', the drive is mounted with read-write capability, but I also get the following message
Unable to mount New Volume Timeout waiting for mount to appear
My second problem is that the inflow and outflow of files from 'New Volume' is very slow. Earlier, while copying a video file from a USB stick to 'New Volume' used to take place at speeds of around 2MB/sec but now it barely touches 50kB/sec. Also, if I try to download any file into that drive, Firefox simply crashes. Since one of my external hard disks, when failing, saw such reduction in file transfer speeds, I checked the SMART status of my hard disk but the results seem to indicate a healthy disk

Any help with either of the problems would be highly appreciated.
