Data writing method and device, equipment and medium

The invention discloses a data writing method and device, equipment and a medium, and relates to the technical field of data storage. The method comprises the steps that after a disk loading event is monitored, a write-in data partition of a disk is determined; performing exception detection on the write-in data partition to obtain an exception detection result and an exception category of the write-in data partition; determining a target data partition from the write-in data partition and the at least one backup data partition according to an anomaly detection result and an anomaly category of the write-in data partition; and writing the data into the target data partition of the disk. According to the technical scheme, it can be ensured that the data are normally written into the disk, and the stability of data writing is improved. 本发明公开了一种数据写入方法、装置、设备及介质，涉及数据存储技术领域。该方法包括：监听到磁盘装载事件后，确定磁盘的写入数据分区；对写入数据分区进行异常检测，得到写入数据分区的异常检测结果和异常类别；根据写入数据分区的异常检测结果和异常类别，从写入数据分区和至少一个备份数据分区中确定目标数据分区；将数据写入磁盘的目标数据分区中。本发明实施例的技术方案，能够
