• Close background apps to free up system resources
• Ensure iPhone has adequate battery power
• Check that external drive isn't nearly full
• Test transfer speeds with smaller files first

Compression Fails on External Storage

Solutions:

• Ensure external drive has sufficient free space (2x source size)
• Check that files aren't locked or in use by other applications
• Verify external drive connection remains stable during processing
• Try processing smaller batches to avoid overloading the connection
• Use local processing then transfer, rather than direct external processing
