Problem
A card formatted in an incompatible filesystem cannot sustain the camera's intended recording mode despite having sufficient free capacity.
Solution
Root Cause / Diagnostic:
Using cards formatted in exFAT/FAT32 with non-standard cluster allocation sizes on a computer causes file allocation errors in camera firmware. The camera cannot maintain sustained write buffer throughput, resulting in recording failure.
Actionable Fix:
1. Always format memory cards directly inside the target camera body using the camera's internal format utility before every production.
2. Avoid formatting camera media on external PC/Mac operating systems unless performing a full low-level sector format followed by camera format.
3. Confirm file system status in camera system information; verify storage capacity and available recording time display correctly.
Pro Tip:
Formatting cards exclusively in the host camera ensures optimal cluster allocation size and prevents cross-platform file fragmentation.
