1. Check Drive Format (Most Common)

• Mac: Drive must be Mac OS Extended (Journaled) or APFS – not exFAT.
• Windows: Must be NTFS – not FAT32/exFAT.
• Solution: Copy session to a correctly formatted internal or dedicated audio drive.

6. Background Process Kill List (Windows)

• Disable SysMain (Superfetch)
• Disable Windows Search indexing on audio drives
• Turn off Real-time protection in Windows Defender (temporarily)

When None of the Above Works

• Corrupt session: Roll back to an auto-backup (Session File Backups folder).
• Hardware issue: Try another SATA/USB cable, port, or different drive.
• Update Pro Tools: Avid fixed several -9400 series errors in 2024–2025 updates.
