Hi,
i own a small debian wheezy server, containing 2 internal HD's, 1 USB 16Gb disk, and one 1TB USB drive.
i noriced, by using the command df -h, that my 2nd HD is not been mounted to the system.
Code:
/dev# df -h

based on this info i am pretty much sure that /dev/sdb1 is my 2nd internal HD.
by performing mkfs.ext4 /dev/sdb1 i should be able to ad a FS to it, and by mounting the device it should be reachable.
my question is, how i am be sure that /dev/sdb1 is truelly my 2nd HD?
i am afraid that i break something by performing the mkfs-command
