I was able to copy all the data from the fail disk... after it was done I decide I will clear it, make new partition, new format... test again and it passes 
) I'm still not sure I should trust it, but I guess I can use it for a scratch/temp disk until it really fail.
I can't ever remember Window giving me any warning before either, is it maybe something new in 8.1? I have gotten them from IRST driver before though... but I didn't install it on my server just left it with the drivers from the chipset package since it have better hotswap supports.
Oh wow you got lucky!!
I wouldn't trust the drive but that's sweet.
