Why does my tool report an error that physical length does not match the logical length of the partition?
This means that the partition table is inconsistent, and may be inaccurate. Modifying a disk with an inaccurate partition table usually requires an expert to reduce the almost certain chance of data loss. The severity of this message is dependent on the size of the disk. Due to historical limitations, most (but not all) computer BIOSs only support disks with less than 1024 cylinders. Booting the operating system depends on the bios, therefore (on such systems), the entire operating system must fit within this 1024 cylinders.. For the same historical reasons, the partition table format only supports reporting disk sizes of 1024 or less cylinders. Many disks today have more than 1024 physical cylinders but by convention the partition table records exactly 1024 cylinders. The operating system still needs to know where the actual partitions begin an end beyond the first 1024 cylinders and this is recorded in the partition table. A large disk with more than 1024 cylinders will have a logica
