[clug] ntfs-3g anyone?

[Tony Lewis]

It's complete speculation but I'd consider if the USB port is dodgy 
inside your Linux system.  Maybe it's not delivering enough power or 
good enough data connection. Maybe the 2.5" HDD is right on the limit of 
the power draw, so any other flash drive you put in doesn't have that 
problem.
