Erase User Data
All data that you have written to the FieldFox can be erased with the press of a
button. You would do this if your FieldFox is located in a secure environment
and must be routinely erased of sensitive data.
All data is deleted from the FieldFox internal “UserData” partition. This
includes all State files and Trace + State files (*.sta), all Data files (*.csv, *.snp),
all Picture files (*.png), all Cal Kit files, and all Cable files.
External media that is inserted (mini-SD card or USB flash drive) is NOT
erased.
The “Lost Clusters“ folder and files are NOT erased because they are part of the
file system housekeeping.
