The HD was a NAS device but it failed at startup to get a network connection. 
A friend of mine had a look at it and transformed it into an USB device. Their 
are 2 partitions on it, linux ext2 filesystem, one partition is small and used 
by the device self the other partition has the data. I can mount the data 
without problem, but ls gives INPUT/OUTPUT error  for certain 
files/directories, while others are still accessible. Those files/dirs I can 
access have been transferred to another HD, but their are still some file/dirs 
I would like to recover.
