Yes, but NTFS is not a native file system for linux. And unlike FAT, that
is quite well supported by linux and other OSes for reading and writing
operations, NTFS specs were not full-disclosed and the linux
implemenation for NTFS is not at the same level as FAT. There are no
problems (or there shouldn't be) when reading these kind of volumes but
writing is a different thing.
So when you have to deal with NTFS (which means you have access to a
windows box) it is better to use windows native tools to test and repair
and NTFS filesystem.
In brief, there is always a risk in using NTFS from a non-windows

Godd, but again, have you tried the manual mount?
I insist in this point because:
1/ Any error you get will be quickly displayed in front of you :-)
2/ In the event there is a problem with GNOME of FUSE tools, the disk
will be able to be mounted manually

I don't like those entries... let me search.
Okay, look at this article:
Which also agrees with my view of making a scandisk and running a defrag
from a windows based machine. I would do it, just to discard there isn't
any problem in the filesystem.

Wise decision. Did you also run the filesystem check tools?

Yes, it's annoying :-(
Maybe you can partition the drive and use two filesystems, one to use
from WIndows (formatted as NTFS) and the other to use from linux (with

Yes, many people have experienced that, it's sadly a well-known ntfs "by-
design" issue. You will have to find a convenient way to be able to deal
with NTFS by using different partitons as I already suggested.
