A method of facilitating prediction of a disk failure The method includes obtaining operation information and failure information associated with a plurality of disks, wherein the plurality of disks comprising a first set of disks indicated by the failure information as having a failure and a second set of disks indicated by the failure information as having no failure; determining validity of the failure information associated with a first set of disks based on system context information related to the storage system comprising the first set of disks; and in response to determining that the failure information associated with at least one of the first set of disks is valid, generating a machine learning model based on the operation information and the failure information associated with the first set of disks.
