I use Windows 10 pro, i have updated system.
I have 4 hard drives, two SSDs, one HDD and on USb. my Kingstone SV300S37A120g ( 18947hours working. Sata/600, Firmware 60AABBF0, Total Writes 17790) is used for page files, temp files and cache processes, but when i try to use it as a storage drives it periodically delete my files. Does anyone knows why and how to make it stop. Crystal Disk info shows its health as good 96% Windows check cant find any problems with this disk, but i cant try to defragment it or optimize it. That option is greyed out.

I work on my computer, as a tech artist and move around a lot of files.
Right now i have over 100gb free space, on the disk, after it itself deleted some of my work files. Before that i had somewhere between 20-50gb free

Kingston V300. You have the infamous version that was known for the bait-and-switch fiasco, utilizing the SandForce SF-2281 controller no doubt. This controller relies on compression which is unusual nowadays. In any case, I would advise backing up its data and engaging in a secure erase. These drives tend to have MLC and a relatively good write amplification factor (WAF) due to compression - this technology is now used in Seagate's enterprise SSDs - so you probably had mapping corruption at some point due to power loss or a PC crash. A secure erase will wipe the mapping table.

Did you bought this drive for a very low (like unrealistic low) price?

Do Windows want to run check on the drive often?
the anwser for both questions would be no. I bought this drive in a chainshop in big mall. I still ahve waranty, problem is moved abroad, and have no way of using it.
