Security Function; Partition Types - Transcend jetflash User Manual

Partition Types

UMSDTools can be used to partition JetFlash into three partition types. Before
partitioning (Resize), you need to understand the following terms and concepts.
Type 1: 『Public Area Only』Type
This is the default partition type for JetFlash, which makes the entire JetFlash
memory accessible by anyone. Access to data is unrestricted. No secure data
area is established. If Security function had been previously setup, it is cancelled
if this partition type is selected.
Type 2: 『Security Area』Type
JetFlash is partitioned into a single Logical Unit Number (LUN) identified device,
which contains a Public Area and a Security Area. Secure data can be
established in the Security Area, which is protected by password. As for the
data in the Public Area, access is unrestricted.
Security Area
Both data areas cannot be seen at the same time. You must "Log In" by
entering the correct password to access data in the Security Area. You
switch from Security Area to Public Area by using "Log Out".
Type 3: 『Public Area + Security Area』Type
JetFlash is partitioned into two LUN identified devices—a 『Public Area Only』
Type device and a 『Security Area』Type device. A『Public Area Only』Type
device is a Public Area with unrestricted access to data. A『Security Area』
