If a brand new SanDisk Extreme 1TB SSD was initially detected but is no longer visible on a Windows 10 desktop, it could indicate a connection issue or a potential problem with the SSD itself. Troubleshooting steps include checking cable connections, trying different USB ports, and testing the SSD on another device to isolate the issue.
