Vaio support contacted me saying Win 10 was available for my exact model, SVE17122CXB 10+/- days later I downloaded & installed it. I lost all my Win XP Pro files. Twenty days later the Vaio CRASHED. SONY will be GLAD to charge me, but won't even acknowledge responsibility for the problem. They blame MS.
I tried RECOVERY now everything is GONE again and Win. 8 seems to be half working i.e. no drivers, no browser, etc.
I NEED, urgently, to find a compatible replacement HD for the SVE17122CXB / SVE171E12L, so I can 'try' to recover files etc. and Win 7 64bit OS so I can start again!
I have time SENSITIVE files I've got to access ASAP. I was 'ready' to order a HD & Win 7 - 64, but I was WARNED installing an incompatible HD will DELAY me even MORE.
