Hello Rich.
My HDD is no 'Advanced Format' drive. I´ve tried it with another HDD, same model, same manufacturer, same size as the one which was originally build in my VAIO. This HDD got no bad sectors and was tested before. HDD is 100% ok.
The Error is the same! Error 334 at 0% during System Recovery with original recovery discs. I think there have to be a problem with the recovery software itself, because nothing else was changed on the laptop since I bought it.
There is no way to solve the problem. I´m so annoyed about Sony!
