Hard disk, being an integral part of computer, is the main storage device of computer data. It features one or more rotating rigid platters on a motor-driven spindle within a protective enclosure. Data is encoded magnetically by read/write heads that float on a cushion of air above the platters. is the 512-byte boot sector that is the first sector of a partitioned data storage device such as a hard disk. The boot sector of a non-partitioned device is a volume boot record. These are usually different, although it is possible to create a record that acts as both; it is called a multiboot record. The MBR is not located in a partition, it is located at a main boot record area in front of (with a lower LBA sector number than) the first partition. In cases where the disk has a BIOS overlay or boot manager installed, the partition table may be moved to some other physical location on the drive; e.g., a partition manager often places a copy of the original MBR contents in the second sector then hides itself from any subsequently booted OS or application, so the MBR copy in sector 1 is treated as if it were still residing in the first sector. MiniTool Partition Wizard is the very partition manager to fix MBR with powerful functions.
