30. Enable Read/Write in User Mode

To set the diskAshur M to Read/Write, first enter the "User Mode" as described in section 13. Once the drive is in User Mode (solid

GREEN LED) proceed with the following steps.
1. In User mode, press and hold down "7 + 9"
buttons. (7=Read + 9=Write)
2. Press KEY ( ) button
Note: 1. If a User set the drive as Read-Only, Admin can override this by setting the drive as Read/Write in
Admin mode.
2. If Admin set the drive as Read-Only, the User cannot set the drive as Read/Write.

31. Brute Force Hack Defence Mechanism

The diskAshur M incorporates a defence mechanism to protect the drive against Brute Force attacks. By default, the initial shipment

state values of the brute force limitation (consecutive incorrect PIN entries) for both the Admin PIN and User PIN is 10 and 5 for the
Recovery PIN. Three independent brute force counters are used to record the incorrect attempts for each PIN authorisation (Admin, User
and Recovery) as set out below.
• If a user enters an incorrect User PIN 10 consecutive times, the User PIN will be deleted but the data, Admin PIN and Recovery
PIN remain intact and accessible.
• If an incorrect Recovery PIN is entered 5 consecutive times, the Recovery PIN is deleted but the data and Admin PIN remain
intact and accessible.
• If an incorrect Admin PIN is entered 10 consecutive times, the drive will reset. All PINs and data are deleted and lost forever.
The table below assumes that all three PINs have been set up and highlights the effect of triggering the brute force defence
mechanism of each individual PIN.

Note: The brute force limitation is defaulted to initial shipment state values when the drive is completely reset,
or self-destruct feature is activated, or brute forced. If Admin changes the User PIN, or a new User PIN is set when activating
the recovery feature, the User PIN brute force counter is zeroed (0) but the brute force limitation is not affected. If Admin
changes the Recovery PIN, the Recovery PIN brute force counter is zeroed.
Successful authorisation of a certain PIN will zero the brute force counter for that particular PIN, but not affect the other PINs
brute force counter. Failed authorisation of a certain PIN will increase the brute force counter for that particular PIN, but not
affect the other PINs brute force counter.
