Wife picked up new VPCEF3E1E yesterday.
Setup machine today for her, all very nice.
Came to creating recovery media (I started in IT over 35 years ago so am well versed in hardware being known to go "phut"). Wouldn't do it. 4 times. With & without "verify".
Windows Update & Vaio update both clean, all updates applied.
Using new Verbatim DVD-Rs. Used same ones with last 2 weeks to create recovery media for an HP machine satisfactorily.
DVD driver works on the laptop (both read & write, I tried it).
Suggest Sony kindly advise me how to fix, at no cost to me or the wife, this probelm or send us revoery media - also at no cost to us.
Happy new year to all my readers...
