How the SATA Drive Works with Your 8240 DVR
Recordings are balanced between the internal hard drive on the 8240 DVR and
the external SATA drive as follows:
• A recording is not split between an internal and external hard drive.
• The 8240 DVR automatically stores complete programs using the following
space available logic:
- If the external SATA drive has more space available, the SATA drive
stores the next recording.
- If the internal hard drive on the 8240 DVR has more space available, the
internal hard drive stores the next recording.
