I have a VGN-FS515B - when I switched it on a black screen comes up saying windows did not open properly. I have tried all the options offered to open it but nothing is working?
I'll suggest running SeaTools for DOS http://www.seagate.com/support/internal-hard-drives/consumer-electronics/ld25-series/seatools-dos-master/ - you'll need to extract it and put it onto a disk.
