Crystaldiskinfo....what does it mean?

StevieP · 12 May 2020 at 14:20

I've recently taken a Crucial SSD out of my dad's PC because the OS started exhibiting some problems in terms of searching for and opening files and folders etc and so I've done a fresh install on a bigger capacity SanDisk SSD.

However, before I did so I ran Crystaldiskinfo and it popped up saying the drive was at 96% (whereas the SanDisk was coming up at 100%)

Now I've got no way of knowing whether it was the drive that was/is faulty but I'm hoping it's fixed the problem nonetheless!

My question is, what does 96% actually mean in terms of the quality/stability of the drive?

Should be fine at 96 mate thats only 4 percent less than new so nothing to worry about

This was my first instinct too but then it got me to thinking about how these scores are determined - I mean I can't say for absolute certainty that the drive was the cause of the issues but the fact that his system went pear-shaped AND the drive reported less than 100% has made me wonder!

I don't know how they're determined but wouldn't have thought it was drive causing issue to be honest could have been a conflict or some sort of malware or just a dodgy Windows update

These sort of percent calculations are generally based on how much data has been written to the drive over its lifetime

My RAID0 array is now at 86$ and working like a weapon, I wouldn't worry about it.
