Preparing a new disk for use on a Linux system can be quick and easy. If you do not have any special requirements, it is probably better to use GPT at this point. Hub for Good As you can see, the lsblk command is showing me my SSD ‘sda’ where Linux Mint 18.1 is installed, ‘sdb’ is a USB Flash Drive, and ‘sdc’ is 1TB internal hard drive. When you know the name the kernel has assigned your disk, you can partition your drive. All rights reserved. Supporting each other to make an impact. Reformatting and TRIM can be considered like defragmenting a hard drive, while the technology is different, the process achieves a similar result: removing saved files that are no longer needed. Save and close the file when you are finished. You get paid, we donate to tech non-profits. Managing storage devices — whether they are internal hard drives, SSDs, PCIe SSDs, or external USB devices — is always a tricky task. To choose the GPT standard, pass in the disk you identified like this: If you wish to use the MBR format, type this instead: Once the format is selected, you can create a partition spanning the entire drive by typing: If we check lsblk, we should see the new partition available: Now that we have a partition available, we can format it as an Ext4 filesystem. This is the general process you can use turn a raw disk into a filesystem that Linux can use for storage. MAJ:MIN denotes the major and minor device number. Now we can create partitions. We can check if the the disk is available in the output from the df command: You should also be able to see a lost+found directory within the /mnt/data directory, which typically indicates the root of an Ext* filesystem: We can also check that the file mounted with read and write capabilities by writing to a test file: Read the file back just to make sure the write executed correctly: You can remove the file after you have verified that the new filesystem is functioning correctly: Your new drive should now be partitioned, formatted, mounted, and ready for use. With your freshly formatted drive, you can install the operating system or start installing programs. Consider using more persistent disk identifiers like /dev/disk/by-uuid, /dev/disk/by-label, or /dev/disk/by-id. For this tutorial, we’ll mount the drive under /mnt/data. How to Format a Solid State Drive (SSD) Formatting (actually re-formatting) a solid state drive (SSD) is a quick and simple process to restore the drive to a clean state, similar to when the drive was new.

The /dev/sd* and /dev/hd* disk identifiers will not necessarily be consistent between boots, which means there is some danger of partitioning or formatting the wrong disk if you do not verify the disk identifier correctly.

To see how the partitioning has worked, run the print command: It will display the partitions you created. Information, products, and/or specifications are subject to change without notice. This is the basic format of the command: If I want to use all the space and create one big partition I will run this command: Here 100% means it will use all the available space. To do this, pass the partition to the mkfs.ext4 utility. If you did not mount the filesystem previously, you can now mount it by typing: After we’ve mounted the volume, we should check to make sure that the filesystem is accessible.

A small solid state drive would be perfect for the OS to live on, maybe 32 GB at most, and you could throw the swap partition on the beginning of a 1 or 2 TB “green” drive that’s mounted on /home. It’s important to note that solid state drives do not need defragmenting, the TRIM command is similar in effect to defragmenting. Now we have to create a new partition table.
