Yes. The atime option only makes sense for a native Linux file system like 
ext3. But it is a default anyway, so you don't need it.

With default fstab I meant the one generated by the installer because it 
is different for every machine. However, from your original mail I made a 
file which should be like your original one. I have attached it to 
prevent line wraps. Before you use it, make a backup of the one you have 
now, just in case I made an error.

The problem is that you have the same device name for external drives if 
they are not present simultaneously. The first connected disk is sda, the 
second is sdb. But fortunately there is a solution. Give the partition of 
the external disks labels as it is explained at this page 
<>. E.g. use NTFSDISK for 
the external disk and PENDRIVE for the pendrive. Then the entry for your 
external disk would look like this:

LABEL=NTFSDISK /media/ntfsdisk ntfs-3g defaults,force,noauto 0 0

But you should make a directory /media/ntfsdisk before using the external 
disk. The pendrive should be handled automatically.
