There are a couple commands to list the available drives on Linux.
- The proc partitions file
Running the following command will list all the drives and partitions that were detected on Linux.
- Code: Select all
cat /proc/partitions
The output will look something like this:
- Code: Select all
major minor #blocks name
8 0 488386584 sda
8 1 486296576 sda1
8 2 1 sda2
8 5 2086912 sda5
8 16 244198584 sdb
8 17 244196032 sdb1
Where the "sda" list the first SATA drive and the size in bytes.
The "sda1" is the first partition and it's size in bytes and so on.
The "sdb" is the second drive and the "sdb1" is the first partition on the second drive.
Now that you know which drives are listed, you can use the cfdisk command to determine the file system on the partitions.
- fdisk "note this can be dangerous if you write the incorrect settings"
If you run the following command, you will see the drive's listed partitions and what file systems are on them.
Note that you just use the drive, no partition numbers.
- Code: Select all
fdisk /dev/sdb
Press "p" to print the list of partitions.
The output should look like this:
- Code: Select all
root@servername:~/# fdisk /dev/sdb
Command (m for help): p
Disk /dev/sdb: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/sdb1 1 30401 244196032 c W95 FAT32 (LBA)
Command (m for help):
The "System" column will show the listed file system for each partiton.
Press "q" to quit this program.
