Thanks to all who answered. 

I tried mounting it with -force, which in principle ought to have permitted 
writes, but even though the write operation went as I would have expected 
(messages about copying n files then n-1 files all the way down to zero), 
after the copy I saw no new data on the drive. PITA.

So now I've copied all the data to a ntfs usb drive and will next plug that 
into the macbook pro to see if I can get the data there. And the hfsplus 
volume works with the macbook pro, so in principle.....

crossing my fingers...
