Re: ntfs mount problems (dfly 3.0.2 + ntfsprogs)

Hi Raimundo,

Do you think it is possible to try the copy using an internal HDD? So that  
we can discard any USB issue.

Also which program are you using to do the copy? Have you tried  
cpdup/rsync? Is there a consistency in the size of the files (ie. mp3s,  
movies) or is it completely random?

I would like to try to reproduce it myself to see if I can track it down.  
Otherwise, it would be quite hard to find it.
