Problem
An exFAT media SSD is unplugged while the camera-copy process still has open file handles, leaving directory metadata inconsistent and making the next ingest mount unreliable.
Solution
Root Cause / Diagnostic:
exFAT lacks file system journaling, meaning directory allocation tables are updated non-atomically. Unplugging the drive while write buffers remain uncommitted leaves the File Allocation Table corrupt, causing mount failures or orphaned file clusters on subsequent connections.
Actionable Fix:
1. File System Repair: Execute `chkdsk X: /f` on Windows or `diskutil repairVolume /Volumes/DriveName` on macOS to rebuild damaged exFAT directory pointers.
2. Ingest Buffer Flushing: Always trigger manual unmounting via OS eject controls or run `sync` in terminal before disconnecting storage media.
3. Filesystem Reformat Standard: Reformat ingest SSDs to journaled file systems (APFS for macOS, NTFS for Windows) or deploy ruggedized offload docks with automatic cache flush.
Pro Tip:
Avoid exFAT for primary production capture drives; non-journaled file systems risk catastrophic directory tree corruption from a single accidental cable pull.
