How To Find Hard Disk Drive Details In Linux
This guide lists various methods to find Hard disk drive details in Linux operating systems. Using the below methods, you can able to find the hard disk make, hard disk type, size, firmware version, partition tables and other hardware parameters. First, we will see how to display hard disk details with hdparm command line utility.
Hdparm is a command line program to get or set hardware parameters for PATA, SATA, SAS and SSD devices. It accepts any device as mass storage that is connected to IDE, SATA, SAS interfaces, so we can even retrieve information about CD/DVD drives as well. Using hdparm utility, we can tune the hard disk or DVD drive, test the HDD or SSD speed, reduce noise level by activating acoustic mode, turn energy-saving mode on or off, enable or disable sleep mode, enable/disable drive cache and even erase drives securely. Hdparm is written by Mark Lord, the lead developer and maintainer of the (E)IDE driver for Linux, and current contributor to the “libata” subsystem.
A word of caution
Even though hdparm offers significant advantages to increase disk performance, it is also EXTREMELY DANGEROUS. It will very likely lead to massive data loss when some parameters are misused. The hdparm documentation suggests that YOU SHOULD NOT USE SOME COMMANDS AT ANY CIRCUMSTANCES. So I’ve excluded such dangerous commands in this guide. More importantly, It is always recommended to backup your hard drive before testing hdparm on your Linux system.
1.1. Install hdparm on Linux
Hdparm comes pre-installed in most Linux distributions. If it is not included for any reason, install hdparm on your Linux system using the default package manager.
On Arch Linux, Manjaro Linux:
$ sudo pacman -S hdparm
On Debian, Ubuntu, Linux Mint:
$ sudo apt install hdparm
On Fedora, CentOS, RHEL:
$ sudo dnf install hdparm
$ sudo zypper install hdparm
1.2. Find Hard Disk Drive Details In Linux Using Hdparm
To display detailed information of the hard disk, simply run hdparm with sudo or root privileges as shown below:
$ sudo hdparm -I /dev/sda | less
Here, sda is my hard disk. Replace it with your own device. Here I have used “less” command for interactive reading. Press ENTER key or hit UP/DOWN arrows to go through the rest of the output. Press q to exit when done.
Sample output from my Ubuntu system:
/dev/sda: ATA device, with non-removable media Model Number: ST9500325AS Serial Number: 5VEQTRV0 Firmware Revision: D005DEM1 Transport: Serial Standards: Used: unknown (minor revision code 0x0029) Supported: 8 7 6 5 Likely used: 8 Configuration: Logical max current cylinders 16383 16383 heads 16 16 sectors/track 63 63 -- CHS current addressable sectors: 16514064 LBA user addressable sectors: 268435455 LBA48 user addressable sectors: 976773168 Logical/Physical Sector size: 512 bytes device size with M = 1024*1024: 476940 MBytes device size with M = 1000*1000: 500107 MBytes (500 GB) cache/buffer size = 8192 KBytes Nominal Media Rotation Rate: 5400 Capabilities: LBA, IORDY(can be disabled) Queue depth: 32 Standby timer values: spec'd by Standard, no device specific minimum R/W multiple sector transfer: Max = 16 Current = 16 Advanced power management level: 254 Recommended acoustic management value: 208, current value: 208 DMA: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 udma5 *udma6 Cycle time: min=120ns recommended=120ns PIO: pio0 pio1 pio2 pio3 pio4 Cycle time: no flow control=120ns IORDY flow control=120ns [...]
As you can see, the hdparm displays the hard disk’s model number, serial number, firmware revision followed by hard disk configuration (no of cylinders, heads, sectors), DMA settings, list of enabled features, security parameters etc. All functions found under “Commands/features” section and marked with an asterisk are currently active.
Similarly, you can check information of other devices.
$ sudo hdparm -I /dev/sdb | less
$ sudo hdparm -I /dev/sdc | less
When running hdparm with no options, -acdgkmur is assumed. Refer man pages to know what each option is for.
$ sudo hdparm /dev/sda
/dev/sda: multcount = 16 (on) IO_support = 1 (32-bit) readonly = 0 (off) readahead = 256 (on) geometry = 60801/255/63, sectors = 976773168, start = 0
For more details, refer man pages.
$ man hdparm

If you want to display only the physical devices, use “-d” flag.
$ lsblk -ido KNAME,TYPE,SIZE,MODEL
6. Find Hard Disk Drive Details In Linux Using Fdisk and Sfdisk Commands
Fdisk and Sfdisk commands are used to create and manipulate partition tables. fdisk is a dialog-driven program for creating and manipulating partition tables whereas sfdisk is a script-oriented tool for partitioning any block device. Both are part of util-linux package which comes pre-installed in all Linux distros.
To get the HDD details, run fdisk as root or sudo user with “-l” flag:
$ sudo fdisk -l
[...] Disk /dev/sda: 465.78 GiB, 500107862016 bytes, 976773168 sectors Disk model: ST9500325AS Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x8dd04bfd Device Boot Start End Sectors Size Id Type /dev/sda1 * 2048 976771071 976769024 465.8G 83 Linux [...]
The usage of Sfdisk is same as fdisk. To list HDD details using Sfdisk, run it with -l flag with root or sudo privileges:
$ sudo sfdisk -l
To exclude the details of dm (device mapper) devices from the output, run:
$ sudo fdisk -l /dev/sd?
$ sudo sfdisk -l /dev/sd?
Disk /dev/sda: 465.78 GiB, 500107862016 bytes, 976773168 sectors Disk model: ST9500325AS Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x8dd04bfd Device Boot Start End Sectors Size Id Type /dev/sda1 * 2048 976771071 976769024 465.8G 83 Linux
7. Find Hard Disk Drive Details In Linux Using /proc
The /proc is a special virtual filesystem in Unix-like distributions. It is also known as process information pseudo-file system. It doesn’t contain any ‘real’ files but runtime system information such as processes, system memory, mounted devices and hardware configuration etc. Each device details are stored in a separate directory under /proc directory. The storage devices’ details will be available in “/proc/scsi/scsi” file.
$ cat /proc/scsi/scsi
