获得了一个新磁盘，并尝试将其安装到我的Centos盒中。它采用NTFS格式，因此我需要重新格式化。我做到了：
sudo fdisk /dev/sdb
Disk /dev/sdb: 2097.2 GB, 2097152000000 bytes, 4096000000 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x00000000
sudo mkfs.xfs -f /dev/sdb1
meta-data=/dev/sdb1 isize=512 agcount=4, agsize=127999936 blks
= sectsz=512 attr=2, projid32bit=1
= crc=1 finobt=0, sparse=0
data = bsize=4096 blocks=511999744, imaxpct=5
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0 ftype=1
log =internal log bsize=4096 blocks=249999, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
然后我尝试安装它：
sudo mount -t xfs /dev/sdb1 /mnt/usbdisk/
mount: mount /dev/sdb1 on /mnt/usbdisk failed: Structure needs cleaning
sudo xfs_repair -L -d /dev/sdb1
Phase 1 - find and verify superblock...
couldn't verify primary superblock - not enough secondary superblocks with matching geometry !!!
attempting to find secondary superblock......
经过数小时的努力，我停了下来。
sudo xfs_db /dev/sdb1
Metadata CRC error detected at xfs_agf block 0x3d08fe01/0x200

如何将新的磁盘驱动器恢复到可以安装到Centos盒中的空白xfs磁盘上？
