Problems solved by technology
Therefore, only by setting a threshold to judge whether the operation fails, and thereby determine whether the corresponding data block is a bad block, there may be a case of misjudgment; and after marking a data block as a bad block, the data block will be If it cannot be used normally, if there are frequent misjudgments, the storage space of the solid state drive will be reduced, resulting in a waste of storage space

The invention discloses a bad block marking method, comprising: obtaining the execution time of the target operation; judging whether the execution time exceeds a preset first threshold; if so, judging whether the target operation is completed, and polling when the target operation is not completed The state of the target operation is detected, and when the number of detections exceeds a preset second threshold, the data block corresponding to the target operation is marked as a bad block. When the execution time of the target operation exceeds the first threshold and the target operation is not completed, the method does not mark the data block corresponding to the target operation as a bad block, but polls and detects the status of the target operation until the number of detections exceeds the second threshold , the data block corresponding to the target operation is marked as a bad block, thereby allowing sufficient execution time for the target operation, thereby improving the accuracy of bad block marking and avoiding waste of storage space. Correspondingly, a bad block marking device, device, and readable storage medium disclosed in the present invention also have the above-mentioned technical effects.
Description
technical field [0001] The present invention relates to the technical field of data storage, and more specifically, to a bad block marking method, device, equipment and a readable storage medium. Background technique [0002] SSD (Solid State Drives), also known as solid disk, is a hard disk made of solid-state electronic memory chip array, which includes multiple data blocks (blocks) for storing data, and each data block is preset with a corresponding storage space . [0003] Generally, when a write operation or a read operation fails, the data block corresponding to the operation will be marked as a bad block, and the bad block needs to be dealt with before it can be used normally. The method of marking bad blocks in the prior art is: preset a corresponding execution time threshold for an operation, and when the execution time of a write operation or a read operation exceeds the preset threshold, mark the data block corresponding to the operation as a bad block. [0004]...
