Hi

I used a similar disk and ntfs partition from my desktop (defect power 
supply) and put it in an usb case.

I think here we have the problem in the middle part of the listing. It 
looks like the partition is rw for owner and group (same user as owner). 
The mount command despite the umask=000 still mounts the disk read only. 
Which is the same what happened using the Storage Device Manager (gui 
for udisks) on the local disk a few days ago. I also remember that I did 
correct the permissions using Windows, again using an usb case. Note 
that on all systems I use the same user-id.

Just a thought: Maybe it has nothing to do with rsync, has there been an 
ntfs related update the last couple of days?

Good luck

Bert
