Problem
A removable SSD is disconnected while an NLE is writing render-cache indexes, leaving the application with stale media paths and partially written cache databases.
Solution
Root Cause / Diagnostic:
Non-Linear Editors (NLEs) maintain persistent SQLite or proprietary binary databases indexing render frames, optical flow, and waveform peaks. Abrupt physical removal severing an active cache commit leaves lock files (.lock/.db-journal) dangling and header pointers corrupted, causing the NLE to encounter read hangs, missing media paths, or crashes upon reopening.
Actionable Fix:
1. Project Cache Index Rebuild: Navigate to the NLE cache directory, delete the orphaned `.db-journal`, `.lock`, and cache index files, and let the NLE re-index media cleanly on startup.
2. Write-Caching Safety Configuration: On Windows, configure the external drive's device policy to "Quick removal" (disabling write caching) to prevent filesystem metadata tearing during unexpected disconnections.
3. Media Relink and Database Verification: Launch the project file, execute a global "Relink Media" command, and confirm all audio waveforms and timeline clips populate without warning flags.
Pro Tip:
Never pull an external drive while your timeline is open; NLEs actively write cache index databases in the background, and an abrupt yank can corrupt your cache catalog and freeze your project.
