My WD-black 500Gb NVMe is loosing data after I do not use my PC for one week. Hardware: WD-black SSD mounted in a Gigabyte Aorus Z390pro and 9700k not overclocked 2x8Gb kingston 3333mhz cl16. The SSD is installed with the motherboards own heatsink and the warranty label is removed. I have 3 other disk, 2 SSD both 256Gb , that both contain the OS, one for gaming, the other one for regular activities like interneting, and one 500Gb HD, for data. On all 3 other disk I never had any data loss. Description: first I did use this NVMe as an Win10 boot, but after two blue screens and the needed OS reinstalling, I transformed it to an data disk. Now I notice, the reason for this BSOD, it is loosing data if I do not use my system for an period of one week. I have done lots of chkdsk repair, installed WD SMARTcheck software and Crystaldisk info software to detect anything, but I only see it is in good healt. Temp 51degr celsius max. BTW, this SSD has been installed using a grounded strap. MBAM and MS virusscan both the most intense scanning, did not detect any trojan, maleware or virus. Couple of weeks ago I did restore the data on the NVMe and use my PC 3 days friday, saturday and sunday, no data loss and after one week non activities it did have data loss again. Interesting points, not quite sure but it appears, mostly the lost files are the last one that I swapped to the NVMe. On the NVMe I have installed data, Steam, AssettoCorsa, racefactor2 and SteamVR. Steam is btw always updating also strange. Question: I need help in going further to solve this, the warranty label has been removed so an RMA would be rejected. Is there something I could test or do an testrun to verify this. Is there an solution for this.
