如何能格式化 ASMT 2115磁碟？

finfin

我有張M.2磁碟，
用個m.2外殼裝住，本來想用來做移動磁碟的，
但當我插入電腦時是看不見它的，
只有去linux個"磁碟"呢個工具入面先見到佢，
並且話係ASMT 2115，想format佢又無得做。
請問要點先可以呢？

唔該。

    我google到呢個網教人用command 去格式化
https://www.cyberciti.biz/faq/linux-disk-format/
但係第一個指令要列出所有磁碟，但係就話permission denied!
而且亦不見部ASMT 2115

@localhost ~]$ fdisk -l
fdisk: cannot open /dev/sda: Permission denied
fdisk: cannot open /dev/sdb: Permission denied
fdisk: cannot open /dev/zram0: Permission denied
@localhost ~]$ fdisk -l | grep '^Disk'
fdisk: cannot open /dev/sda: Permission denied
fdisk: cannot open /dev/sdb: Permission denied
fdisk: cannot open /dev/zram0: Permission denied

之後我用 df -h
就列出機裡面的磁碟，sda, sdb等等，
但係用USB插入的ASMT 2115都係唔見。

your error message said you do not have the permission, either 'su' or 'sudo'.
it is a high risk action for format a disk, you are not suitable for the job.

    我用sudo有列出磁碟呀，
但係都係無見到隻usb插入的被顥示為ASMT 2115的M.2

Permission denied 真係唔易預計到,做乜都有機會出  Permission denied,連簡簡單單只係想用 GEDIT 之類開個文檔 EDIT 都有機會出  Permission denied

    咁你要買本書學下點樣用 linux command line 啦，好多 setup 都係用 Terminal 去做野。Linux 始祖就係得個 command prompt.

before we go further, did you use your m.2 disk anywhere else ? (is it new ?)
let's try few more commands and then we can check the hardware.
post output of the following commands
1) sudo parted -l
2) sudo smartctl -a /dev/sdc
3) sudo dmesg | grep sdc
