On booting into Sparky, I tried to mount the Apps, Data and Distros partitions (all ntfs) with pcmanfm and got the same result: "Operation not Authorized"
Then I opened gparted to make sure I used the correct partition numbers and names.
Then I opened a terminal as root and typed:
# mount -t ntfs-3g /dev/sda5 /media/Apps
ntfs-3g-mount: failed to access mountpoint /media/Apps: No such file or directory
The same thing happened with Data (sda6)
I reinstalled ntfs-3g with synaptic but ntfsprogs wasn't found in the repositories.
I then closed synaptic typed:
# apt-get install ntfsprogs

Package ntfsprogs is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'ntfsprogs' has no installation candidate
I then reopened synaptic and refreshed it.
But I got:

Failed to fetch http://www.deb-multimedia.org/dists/testing/main/binary-i386/Packages.xz Some index files failed to download. They have been ignored, or old ones used instead.
I am going to have to either use another OS or back up my ntfs partitions and convert them to another file format.
Thanks for the tip but the problem persists (although not on Fedora, openSUSE or Calculate (which has another problem at present).
