14.2 Security Protection

QzROM also introduces the concept of Security Protection into FDT, which is optionally set as FDT

disconnects (Note – once set, this cannot be undone).

The majority of devices have two levels of protection, Full (which prevents any later reconnection to the

device) or None (which allows reconnection normally). Newer devices have more levels - allowing a partial

protection of the device and yet still allowing a later connection (but with the protected data region

masked).

There are three options for the setting of security protection:

Automatic – FDT will protect the device as it disconnects. The level of protection will be determined

when Automatic is initially selected, typically ‘Full’. If the device offers multiple levels of protection

then a dialog will appear to allow the user to select the level that should automatically be applied:

Prompt – FDT will ask what to do during the disconnect, i.e. whether to protect or not. The choice is

between full protection (or other levels if supported by the device) or no protection at all. The default is

‘No’.

Figure 14-3 Disconnect Protect choice

None – FDTwill not protect the device on disconnect.

As the disconnect actually happens the result of the operation will be echoed to the Output window.

There are several ways of changing this setting depending on the current mode of operation:
