10.3 Retrieving data
Data are recorded first to a buffer held in flash memory. When the
buffer utilisation exceeds a configurable percentage, a process is
triggered to flush the data to the hard drive. In low power
applications, the hard drive will normally be powered down and, so,
must be powered up and mounted before use. It is then dismounted
and powered down once the flush is complete.
If you wish to work with data on the removable drive, it must first be
powered up. This is done automatically when using the web interface
but must be done manually when working from the command line. If
you wish to work with recent data, a manual flush should first be
performed in order to move the data from the buffer memory to the
drive.
