I am attempting to install an Intel 750 series 400 GB PCIe SSD card into a CentOS 7 system.

The SSD shows up as /dev/nvme0 and /dev/nvme0n1

Attempting to format it with fdisk /dev/nvme0n1 results in:

The partition table has been altered!

Calling ioctl() to re-read partition table.

Error closing file

After attempting to format it dmesg contains:

[ 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

Attempting to write to it with dd results in:

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

What steps should I attempt next to debug the cause of the SSD failing to write?

isdct show -intelssd 1 results in:

ls: cannot access /dev/sg*: No such file or directory

It appears you need to update your kernel to >=3.19.
