I have a Crucial MX100 512GB SSD, performed a fresh format/install of Win 10 a few days ago. Installed a few games on it over the last few days, nothing major. I had about 200 GB left over last night when my computer went to sleep. I powered it on today and Win10 told me I'm running low on disk space!! I check the drive and it says 0 bytes free of 476GB! I right click and "refresh" and it will jump from 600mb available, to 800 mb, back down to 0 bytes.... SSD life still shows the drive is excellent health. Is my drive going bad?? I've never seen this issue before!
