Hi [NAME]  as you do not believe me, search the internet for generic confirmation that M.2 Gen4 NVMe cards are usually backwards compatible with Gen3. Please email the card's technical support for specific confirmation.  Thank you for providing image. It seems that your Windows OS(C:) boot drive is damaged. Please run Check Disk to find and automatically fix any errors.  Using the Chkdsk Utility | Dell US  Disk Error Checking: How to run CHKDSK in Windows 11/10 (thewindowsclub.com)
I have tried a Samsung 970 EVO Plus and now a Western Digital Black SN850 in my 2nd 2280 SSD slot and neither is being recognized by the computer? Are these drives not compatible? Do I need to downgrade to a Gen 3 card? What am I doing wrong?
m15 R4, SSD compatibility?
