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 is NOT erased because it is part of the file
system housekeeping.
How to Erase User Data
Press System 7.
Then Service Diagnostics.
Then Advanced
Then Erase User Data
Then Confirm Erase
Then the following occurs:
o All data files and folders are deleted from the “UserData” partition.
o A large file of 0s is written to all of the free blocks on the partition.
o The large file is deleted. All blocks released by deleting this file are now
available for use.
o The FieldFox is rebooted, which manages the newly-freed data and re-writes
the factory cal kits and cable files.
