## Abstract

The present invention provides a disk detection method and apparatus. The method includes: collecting a set of N pieces of real-time data that are in a one-to-one correspondence with N input/output I/O-related counters of a disk, where the N I/O-related counters include an I/O response time of the disk and a counter affecting the I/O response time; the I/O response time is a time between delivery of an operation request by an application and reception of a response of the disk to the request; determining, according to the N pieces of real-time data, whether the I/O response time is abnormal; and outputting a detection result if the I/O response time is abnormal, where the detection result is used to represent that the I/O response time is abnormal.
