[SOLVED] Can "dcfldd" make a device?

n00b_noob · 11-15-2020, 03:45 AM

Hello,
I'm using Debian 10.6 x86_64 and when I use below command then it make a news HDD:

Code:

# dcfldd if=/dev/zero of=/dev/sdc

After it, I have a "sdc" device and I want to know why and how can I remove it?

Thank you.

that is not a device, but a regular file if it was created by that command. use file /dev/sdc to check it. You can use the usual rm to remove it.

You should really stop and read man dd. Or you are going to be back here complaining about an erased hard drive.

/dev/sdc, that is normally a drive. If you had something mounted there, it would be gone. With no hope of recovery.

What are you trying to achieve?

As has already been stated, you did an extremely risky command.
Please do a quick google search for what dcfldd does and how to use it (it is based on dd), and learn about dd before you wipe something important out.

Yep.
Or, looking at noob's other threads, any man page.
