I have the same issue as the OP. I’ve got a Sandisk i110 128gb ssd embedded (non-removable) in an Asus convertible laptop that is just about 1 year old. I downloaded the SSD Dashboard yesterday and ran it. Everything checks out great except for those two S.M.A.R.T errors saying the drive had 0% spare blocks remaining. It didn’t make sense given the young age of the drive/laptop, the fact the drive was not malfuntioning in any discernable way, and the fact that all other numbers looked great. For example, the dashboard also reports that there is 99% life remaining and the media wear out indicator reads just 1.6%. It also says that there is 33.64 GB free space remaining.
The problem with this false warning is that it is likely causing some folks to go into panic mode and replace their SSDs and/or computers unneccessarily. It has likely also caused SanDisk to make warranty replacements when none were necessary.
I have downloaded Crystal Disk Info and everything looks fine in there. But it would be helpful if SanDisk could change their SSD Dashboard so it wouldn’t return the false positive warning. A simple message thatt the drive being read is not fully supported would be more beneficial. The false positivies are likely giving some folks anxiety attacks and causing them to waste time tracking down solutions.
