Data Loss

The Data Loss indicator will light up red if data is not recorded to a file. If
the Data Loss indicator is not lit, then all of the data was recorded success−
fully.
Data loss is flagged by the recorder when any condition that results in a dis−
continuity of the data stream occurs. The Talon recording system flags this
data loss in both the real−time status as well as in the recording's file header.
The file header also includes a field that contains the location of the last
good (contiguous) data recorded, so the operator can use the portion of the
recording that is still good.
Data loss can happen for a number of reasons. Any time that the storage
drives fail to keep up with the real−time stream of data from either A/D
converters or a digital interface will result in a real−time data loss. This
could happen if the system parameters are set up in a way that results in a
higher aggregate data rate to disk than the system can handle. The following
are other potential causes of data loss:
• An almost full or highly fragmented disk
• Selecting the wrong drive to record each file to
The operator should consider all of these possibilities when observing data
loss and take care to create an environment that results in error−free record−
ing every time.
