1TB microSD failed to be recognized by Windows 7

I bought a 1TB microSD card a couple of days ago. Formatted NTFS. Transferred about 300GB of data, files, videos and photographs. Today, I tried to add more files and my computer did not detected . It is like it does not exist. Used a couple fo different adapters, sd readers, cleaned it up with alcohol and nothing. Other micro SD are read without any issues by the same computer. Can someone please tell me how to access the MicroSD?

Thank you
