摘要：
Methods and systems for preserving a disk geometry when relabeling a storage device containing data migrated from a previous data storage device having different disk geometry. Prior to relabeling, the label of the storage device includes information on the disk geometry of the previous data storage device. An exemplary method includes reading the label of the storage device in response to a request for information related to a disk geometry of the storage device, which is normally answered without reference to the label of the storage device, and reporting the information related to the disk geometry from the label if the label is associated with an operating system that considers a geometry of a storage device when partitioning.
