Ubuntu 添加硬盘

well . . . if you want to make it one big partition:

fdisk /dev/sdb

Now you'll be inside of fdisk

n

this creates a new partition

p

for primary partition

1

will be the number of the disk

Hit enter, to start at the beginning, and enter again to stop at the end.

Then hit w to write and exit.

Once that's done you need to crete the file system:

assuming you want ext3:

mke2fs -j /dev/sdb1

mkdir /newopt

mount /dev/sdb1 /newopt


And Wham! you're good to go. If you want this to automount at boot time you'll need to add a line to your /etc/fstab file:

otherwise you can just mount that bad mother:

mount /dev/sdb1 /path/to/mount

enjoy!

Note:

umount /dev/sdb1 
umount: /dev/sdb1 : device is busy

fuser -m /dev/sdb1
