Notes on Write Protection Filter

Quit SiliconDVR (UTILITY MENU – QUIT), the Windows Desktop shows up.

A folder named "SI" on the desktop links to all necessary Windows Functions

such as Windows Shutdown or ActivateRaw.exe. The “Write Filter” toolset to

turn on and off the Write Filter is situated here.

Why do we need a Write Filter?

In order to give the system a much higher reliability the software is equipped

with a Write Filter that protects the whole internal system drive (path c:\) of

SI-2K from having new data written on it.

This provides additional protection against corruption after the operating sys-

ten (OS) has booted and prevents recordings to be stored directly on the

internal system drive (path c:\), which would ﬁll up the drive and shuts down

the camera.

When does the user need to disable the Write Filter?

Normally you do not need to touch the write ﬁlter function.

IMPORTANT:

In normal operation mode the Write Filter MUST be “enabled” all the time –

otherwise you run into danger of a corrupted software image and therefore a

complete breakdown of your SI-2K camera. Even with enabled write protection

you can change all settings within the SiliconDVR software.

There are three occasions when the Write Filter must temporarily be disabled:

1. Upgrade to a new version of SiliconDVR (lean or full installation)

2. CineFormRAW Activation

3. Any changes need to be performed by a user on the system like monitor

resolution

How to deactive/reactivate the Write Filter?

IMPORTANT:

Systems will be shipped with FBWF enabled – it should be enabled for normal

camera operation.

- Write Filter can be disabled by clicking on the short cut in the SI folder, “Dis-

able Write Filter and Reboot” (Note that to change the state of the Write Filter,

you cannot do a power off shutdown, only a normal shutdown)

- After the automatic reboot, the Write Filter will be disabled and SiliconDVR

can be upgraded, the CineForm key inputted or any other necessary changes

on the system can be performed
