Posted June 17, 2020 I have two 960gb SanDisk SSD's and when I format both of them, the capacity is only 500gb. Disk management shows that the drives only have 500gb with no unallocated space to be seen. Same issue on both identicle drives. What's up?

Posted June 17, 2020 What are the drives (genuine sandisk or wish specials?) ? Can you do a screen grab of disk manager? What do they report as in crystal disk info? Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted June 17, 2020 Download MIniTool Partition Wizard. Then resize (using that program) your partition a little (shrink it by 1GB for example). Apply. Then check. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted June 17, 2020 Before formatting, did you partition them? Were they bought new?

I actually found them in an upgraded server that was running an i5-4000 series cpu. On that machine they both reported as 500gb Link to comment Share on other sites More sharing options...

Posted June 17, 2020 Author Windows reported that one of the drives needed to be repaired, I ran the tool and now one of the drives formats to 800gb Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

On that machine they both reported as 500gb Sounds like whoever used them before had over-provisioned them. By limiting the capacity below the maximum available, the drives may perform better in some circumstances. Best thing to do is to delete all partitions on them (some may be hidden) and create a new partition of the whole space. From your last screenshot, 894GiB = 960GB, but Windows displays GiB as GB. Anyway, that appears to be the correct capacity.

What do they report as in crystal disk info? Windows reported that the drives had issues and directed me to control panel where it ran diagnostics and fixed it! Here is the same info for the second drive, I beleive that the capacity is coming up as 860gb instead of 960 because CrystalDisk reports each drive as having 100gb for NAND flash? Not sure what's up with it. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
