Because Windows doesn't allow me to remove safely the the usb drive, I don't 
know why

No, I would like to read/write both from Windows/Linux, because I want to use 
the drive as a back up storage system

Could I safely delete the option "atime" from the entries? I think something 
went wrong one day, but I didn't realize I was modifying something 
important... :-(

Ok. Please send to me the default fstab, if somebody has one. But my question 
is: Could I add a new entry to fstab for the external ntfs hard drive, 
keeping "untouched" the entry for sda1 (used by the pen drives)?
Something like, for example: /dev/sda2 /media/disk2 ntfs-3g defaults,force 0 
0 ?

I'm wondering if it is possible to customize only the entry for the external 
usb drive, so that Kubuntu could see the drive and the usb pendrive at the 
same time.
If not, I'll try another solution.

Thanks to all have answered to my request, all of you are very kind!
