Formatar unidade grande

Question

Minha situação:

/dev/sda1
/dev/sda2

/dev/sdb1 - ~4TB

Eu preciso formatar a unidade / dev / sdb1
O que preciso para formatar / limpar os dados de uma unidade tão grande?
Qual comando?

    

Answer 1

Depende de qual sistema de arquivos você deseja usar, por exemplo, usando ext4 :

sudo mkfs.ext4 /dev/sdb1

    

Answer 2

A maneira mais fácil seria recriar o sistema de arquivos:

sudo mkfs.ext3 /dev/sdb1

De man mkfs :

mke2fs is used to create an ext2, ext3, or ext4 filesystem, usually in a disk
partition.  device is the  special file corresponding to the device 
(e.g /dev/hdXX).  blocks-count is the number of blocks on the device.  If omit‐
ted, mke2fs automagically figures the file system size.  If called as mkfs.ext3 
a journal is created as  if  the -j option was specified.

The  defaults of the parameters for the newly created filesystem, if not over-
ridden by the options listed below, are controlled by the /etc/mke2fs.conf
configuration file.  See the mke2fs.conf(5) manual page for more details.
