Thanks for all your replies. I have previously found out to my cost that it is better not to use the back up and restore feature on Sonic Stage. I now back up all my music etc using commercial software (and this also backs up all my documents, emails etc).
I take it that Sony now have more effective and reliable software for their portable music devices/MP3 players etc?
I believe that the Sony hardware is excellent but my experience to date is that the hardware suffers due to extremely poor software. Hope that is no longer the case?
Great to hear your views?
Thanks
Gordon
