Abstract
Methods and apparatus for preventing the loss and/or corruption of process data stored by data collection and/or test instruments (referred to hereinafter collectively as 'recording instruments'), which may otherwise result from events such as the removal of aforementioned storage media while data transfer operations are in progress; loss of power to the recording instrument while data transfer operations are in progress; and/or the execution of internal CPU traps or other CPU reset conditions while data transfer operations are in progress. The methods and apparatus contemplated by the invention also provide for the recovery of process data which has been corrupted during a power loss or CPU reset when normal operation of a recording instrument resumes.
