DM series hard drives, such as DM001, DM003, have a common problem, that is, fake ready, that is, after the hard disk firmware is damaged, the hard drive can be ready after power on, but the capacity to identify is 3.8GB. At that time no ATA instructions can be performed, and users can’t enter terminal T level, thus can not perform any terminal instructions. Since any instruction can not be implemented, no hard disk can be repaired. This state is called fake ready fault. Fake ready is not the same with the firmware lock. With firmware lock, users is still able to enter the T-level, and also to perform a small number of instructions, but the fake ready state is that any instructions can not be implemented. There is no solution for this problem before, but now, MRT has launched its own solution, specifically to deal with fake ready DM hard drives, which is definitely a major breakthrough.
