Windows sometimes shows wrong space amounts. Hidden system files eat storage. Deleted files might stay in the USB recycle bin. These invisible files stop new saves from working. Check real space using the Windows Properties tool.

Why this helps:

USB ports can fail over time from heavy use. Front panel ports often have a weak power supply. USB 3.0 ports might not work with old USB 2.0 drives. Testing different ports helps find working connections for reliable file saves.

Why this helps:

• Rules out port-specific problems
• Tests if the USB drive actually works
• Bypasses cannot save files to the USB flash drive port issues
