文件系统限制#

MBR vs GPT#

  • MBR - Master Boot Record
    • 也叫 DOS 分区 - 最早于 IBM PC DOS 2.0
  • GPT - GUID Partition Table
    • 因为 UEFI 而诞生
  • 4096 disk sector - AFD - Advanced Format - 4Kn
    • 自 2010 年开始,厂商大多采用 4k sector
    • 使用 512 实际是使用模拟后的地址 - 512e

The size of this disk is 2 TiB (2199023255552 bytes). DOS partition table format cannot be used on drives for volumes larger than 2199023255040 bytes for 512-byte sectors. Use GUID partition table format (GPT).

重新挂载为可读写#

mount -o rw,remount /

Do you want to remove the signature?#

如果不希望删除 fs 则选择 No
