我正在尝试将 Intel 750 系列 400 GB PCIe SSD 卡安装到 CentOS 7 系统中。
SSD 显示/dev/nvme0
为/dev/nvme0n1
尝试格式化它,fdisk /dev/nvme0n1
结果如下:
The partition table has been altered!
Calling ioctl() to re-read partition table.
Error closing file
尝试格式化后它dmesg
包含:
[ 4978.018955] Buffer I/O error on device nvme0n1, logical block 0
[ 4978.019007] lost page write due to I/O error on nvme0n1
[ 4978.019908] nvme0n1: unknown partition table
尝试使用 dd 写入结果:
dd if=/dev/zero of=/dev/nvme0n1 bs=1M oflag=direct
dd: error writing ‘/dev/nvme0n1’: Input/output error
1+0 records in
0+0 records out
0 bytes (0 B) copied, 30.0685 s, 0.0 kB/s
我下一步应该尝试什么步骤来调试 SSD 无法写入的原因?
isdct show -intelssd 1
结果是:
ls: cannot access /dev/sg*: No such file or directory

看来您需要更新内核至>=3.19。
