Abstract

The invention provides a method for obtaining an FRT table in a solid state disk, which comprises the following steps: processing FRT original data, summarizing FRT data obtained by NAND test into a lower page all list, a middle page all list and an upper page all list for representing A, B, C, D, E, F and G axis data, and the lower page all list comprises three groups of data of FRT1, FRT2 and FRT3; acquiring data position offset tables of the FRT1, the FRT2 and the FRT3; extracting A-axis data, B-axis data, C-axis data, D-axis data, E-axis data, F-axis data and G-axis data from the FRT original data table; and recombining the FRT table, recombining the extracted A, B, C, D, E, F and G axis data, and storing the generated data in a file. According to the method, the FRT table applied to the SSD firmware is finally obtained by performing script analysis on the offset voltmeter obtained by the NAND test, and the FRT table is applied to the SSD firmware, so that the occurrence of read errors is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of file management, in particular to a method and device for obtaining an FRT table in a solid-state hard disk. Background technique [0002] As the main product of storage devices, SSD has rapid technological development and product application. SSD is composed of control unit and storage unit (FLASH chip, DRAM chip); flash memory-based solid-state hard disk is the main category of solid-state hard disk, its internal structure is very simple, the main body of solid-state hard disk is actually a PCB board, and this PCB board The most basic accessories are control chips, cache chips (some low-end hard drives have no cache chips) and flash memory chips for storing data. With the rapid development of information technology-related industries, the demand for storage devices is also increasing. At present, SSDs are widely used in military, industrial control, video surveillance, network monitoring, network termi...
