The application that will probably be available on every system would be fdisk, so i will start with that
fdisk -l
But that is not my favorite, the one i use (Because i have disks of same size so i need more information) is
lshw -class disk
But i still need to know the partitions so fdisk -l will be necessary with that too
There is a third option,
hwinfo --disk
And, because sometimes i want to see parititons too
lsblk
Will do the trick
