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!
Apart from purchasing a new set of recovery media the only other thing I can suggest is to reset the BIOS to defaults and then try the disks again.
Edit: Sorry just re-read your original post and see that you have already reset BIOS to defaults. I wasn't aware that dealers supplied recovery media. I thought the only genuine source of supply was Sony Support...
