Subject: NPLE Rinex problems continue

Dear Colleagues, 

I have tried the remedies suggested by Philippe Moussay (below), but despite
successfully defragmenting the R100's hard drive (including finding and
fixing a bad sector), and clearing all old files from the drive, the Rinex
files immediately continued with wrong time-ordering of some data. 

Any other suggestions are welcome. I will contact 3S, again. 

Regards, 
Jon
