Linux uses logical labels for drives that are then mounted on the filesystem. These logical labels will vary depending on where the drives are mounted, meaning the same hard drive might have different labels at different times, depending on where and when it’s mounted.
When systems have more than one hard drive, Linux simply names them serially by incrementing the last letter in alphabetical order, so the first drive is sda, and the second drive is sdb, the third drive is sdc, and so on.
- sda -- First SATA hard drive
- sdb -- Second SATA hard drive
- sdc -- Third SATA hard drive
- sdd -- Fourth SATA hard drive
Partition Labeling System
- sdal -- The first partition (1) on the first (a) SATA drive
- sda2 -- The second (2) partition on the first (a) drive
- sda3 -- The third (3) partition on the first (a) drive
- sda4 -- The fourth (4) partition on the first (a) drive
To see which ones you have and how much capacity is available in each. You can do this by using the fdisk utility. Using the -l switch with fdisk lists all the partitions of all the drives,
kali >fdisk -l
