Problems solved by technology

However, despite these excellent data storage device features, it is unavoidable that in some cases it will not start normally or cannot be recognized
For example, the deadlock (deadlock) caused by firmware damage or firmware program error will cause the host computer to fail to recognize the solid-state data storage device or cause the solid-state data storage device to fail to start normally.

Embodiment Construction

[0019] The method for the data storage device to enter the read-only memory (ROM) mode and the method for the data storage device to restore data in the ROM mode provided by the embodiment of the present invention can be applied to portable data storage devices such as solid-state data storage devices (SSD) or other electronic products that use a non-volatile memory such as a flash memory (Nand Flash) as a data storage device.

[0020] The initialization of the data storage device mainly includes two stages. The first stage is that the SoC control circuit of the data storage device executes the read-only memory program (Read-Only Memory Code, ROM Code), and the second stage is loading and executing the startup program. (Boot Code) to load and execute the firmware (Firmware). If the initialization is successfully completed, the data storage device enters a ready state. The data storage device repair method provided by the embodiment of the present invention mainly monitors the...

Abstract

A data storage device repairng method is provided, which is adapted to a data storage device. The data storage device includes an SSD controller, a power management circuit, a non-volatile memory, and a reset circuit. The data storage device restoring method includes: the power management circuit determines whether a normal signal from the SSD controller is received within a predetermined time; if not, the power management circuit resupplies power to the data storage device but stops supplying power to the non-volatile memory, thereby the SSD controller stays in a read-only memory mode to automatically execute the data storage device restoring process.

Description

technical field [0001] The invention relates to a repairing method, in particular to a repairing method of a data storage device capable of entering a read-only memory mode to automatically execute a repair program. Background technique [0002] With the development of technology, it will be a trend that solid state data storage device (SSD) becomes the mainstream in the market. This is all thanks to its several advantages such as: fast read and write speeds, superior shock resistance, extremely low power consumption, and more. But despite these excellent data storage device features, it is unavoidable that it cannot be started normally or cannot be recognized in some cases. For example, a deadlock caused by firmware damage or firmware program errors will cause the host computer to fail to recognize the solid-state data storage device or cause the solid-state data storage device to fail to start normally. The existing method is to take out the solid-state data storage devi...
