Problems solved by technology

[0003] In the traditional technology, X-rays are usually used to check whether the solid-state hard drive has solder joints after disk production. When an abnormality occurs in a relatively hidden position of the solid-state hard drive, this rough screening method cannot detect defective products. It will consume a lot of manpower and material resources for abnormal testing, positioning and maintenance, which will cost a lot of economic costs, and the reliability of the test results is low

Abstract

The invention provides a data storage abnormality detection method and device, which relate to the field of hard disk detection. When any digits of the second feedback data obtained twice are flipped, a data storage abnormality detection result is generated according to the position of the digits flipped in the second feedback data read out twice, so that defective products can be easily and accurately detected , In the later stage, there is no need to spend a lot of manpower and material resources for abnormal testing, positioning and maintenance, which saves a lot of economic costs, and the reliability of the test results is high.

Description

technical field [0001] The present invention relates to the field of hard disk detection, in particular, to a method and device for detecting abnormality in data storage. Background technique [0002] Solid State Disk (Solid State Disk) is a hard disk made of a solid-state electronic storage chip array, which consists of a control unit and a storage unit (FLASH chip, DRAM chip). Under normal circumstances, after the solid-state drive is fabricated, high-temperature RDT and BIT aging tests are performed to detect abnormal signal quality caused by the welding of the solid-state drive's platters. [0003] In the traditional technology, X-rays are usually used to check whether the solid-state hard disk is soldered or not. When an abnormality occurs in the relatively hidden position of the solid-state hard disk, this rough screening method cannot detect defective products, so that the defective products are not detected in the later stage. It will consume a lot of manpower and m...
