https://community.intel.com/t5/Intel-Optane-Memory/Problem-with-my-optane-HBRPEKNX0202AHO/m-p/1722782#M9099 <P>I'm having a problem with my Optane drive. One day, it just started not recognizing one part of it. It randomly switches between the 32GB part and the 512GB part. Does anyone have any ideas??? When it recognizes one of the parts, it can be used and shows no problems with its sectors. It's just as if they were two different drives and it's randomly choosing one to access.</P> Mon, 20 Oct 2025 21:58:29 GMT GonzElrond 2025-10-20T21:58:29Z https://community.intel.com/t5/Intel-Optane-Memory/Problem-with-my-optane-HBRPEKNX0202AHO/m-p/1722782#M9099 <P>I'm having a problem with my Optane drive.
