df -T 只可以查看已经挂载的分区和文件系统类型。
Try `df --help' for more information. [root@localhost huanghai]# df -T Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/sda3 ext4 541474624 431342832 82619832 84% / tmpfs tmpfs 16315340 627124 15688216 4% /dev/shm /dev/sda1 ext4 999320 64356 882536 7% /boot /dev/sdb1 ext4 4755888276 193163092 4321133328 5% /data /dev/sdc1 ext4 107406275100 53236939356 48798242192 53% /usr/local/tomcat7/webapps/dsideal_yy/html/down
fdisk -l 可以显示出所有挂载和未挂载的分区，但不显示文件系统类型。

切换成gdisk再试试

parted -l 可以查看未挂载的文件系统类型，以及哪些分区尚未格式化。

lsblk -f 也可以查看未挂载的文件系统类型。
