With sfdisk -s I can see the disk capacity as follows:

$ sfdisk -s
/dev/cciss/c0d0: 143338560
total: 143338560 blocks

How do I see disk details like disk manufacturer? I tried hdparm, but got an error:

$ hdparm -i  /dev/cciss/c0d0
HDIO_GET_IDENTITY failed: Inappropriate ioctl for device

Try these commands:

lshw -class disk  

hwinfo --disk

You may have to install hwinfo.

Concerning hdparm:
hdparm(8) says:

Although this utility is intended primarily for use with SATA/IDE hard disk 
devices, several of the options are also valid (and permitted) for use with 
SCSI hard disk devices and MFM/RLL hard disks with XT interfaces.


Some options (eg. -r for SCSI) may not work with old kernels as necessary 
ioctl()´s were not supported.
  • the command hwinfo & lshw are not installed in my linux – user3266 Dec 22 '10 at 13:36
  • can you provide some more information about your system? – wag Dec 22 '10 at 17:07
  • @jennifer: Install at least one of them! All the information they return is available elsewhere, but they have the advantage of collecting all that information from many different places. – Gilles 'SO- stop being evil' Dec 22 '10 at 19:50
  • Running the command lshw -class disk as a regular user does not display information on disk (Ubuntu 15.04). Hopefully the bottom printed line says "WARNING: output may be incomplete or inaccurate, you should run this program as super-user." Running again using sudo fixes the issue :-) – oHo Oct 20 '15 at 21:13

    The name /dev/cciss/c0d0 indicates the OP's system uses a HP SmartArray hardware RAID controller, and so any "disk" shown by it is actually a RAID set, which may or may not correspond directly to any single physical disk. In that specific situation, you'll need a tool that knows how to talk to the RAID controller and get the information on actual physical drives from it. hwinfo, lshw or smartctl mentioned in other answers all understand some types of hardware RAID controllers; a vendor-specific RAID management tool will usually get the most information. – telcoM May 7 '19 at 4:44

You could read the disk properties directly through sysfs, also check the other files/dirs in /sys/class/block/sda/device/ (replace sda with drive you need).

cat /sys/class/block/sda/device/{model,vendor}

    Use a recent kernel maybe, what distro are you using? try dmesg | less, should see the disks get probed. – OneOfOne Dec 22 '10 at 14:20
  • @jennifer: cat /sys/block/sd?/device/{model,vendor} (/sys/class/block only appeared fairly recently, and your distribution is a little old). – Gilles 'SO- stop being evil' Dec 22 '10 at 19:52

try running smartctl -a /dev/hda (could be sda in your case; cat /proc/partitions will show you the device type to use)

In your case it's behind a cciss controller, so the option should be -d cciss,0 or similar.


I know these answers are 3 years old, but for anyone looking around... In older versions you could find that under (? should be a number):


by doing this:

cat /sys/class/scsi_device/0\:0\:0\:0/device/{model,vendor}

(The backslashes next to zeros are for escaping special char :.)


lsblk (List Block)

You can use lsblk command:


NAME        FSTYPE LABEL   MOUNTPOINT                      SIZE MODEL
nvme0n1                                                  119.2G TS128GMTE110S                           
├─nvme0n1p1 vfat           /boot/efi                       512M 
└─nvme0n1p2 ext4           /                             118.8G 

Perfectly informed, my NVMe SSD is a Transced 110S 128GB (TS128GMTE110S)



Either gnome-disks or just "Disks" on the Ubuntu 18.10 dash:

enter image description here

This shows that I have a SAMSUNG MZVLB512HAJQ-000L7 in my Lenovo ThinkPad P51.

TODO why: for some reason, my SSD model was not showing clearly on either of:

sudo lshw -class disk
sudo hwinfo --disk
  • lshw did not how the SSD at all, only my hard disk

  • hwinfo did show both, but for the SSD said just:

    Model: "Samsung Electronics Disk"

    while for the HD it contains the actual model...

    Model: "ST1000LM035-1RK1"

This one from https://unix.stackexchange.com/a/5087/32558 worked though:

cat /sys/block/nvme0n1/device/model

lsblk (List blocks) gives a list with device, size, type and mount_point

    this is a command specific to hp raid controllers - so it is not useful here – geruetzel Oct 27 '16 at 15:28

The lssd command can also help you.

  • Can you provide some sample output or an explanation of where to find this tool? It's not available in my Fedora 20 system, for example. – slm Sep 9 '14 at 2:09
  • @slm That is part of the fibreutils package that originates/d from HP. – Anthon Sep 9 '14 at 3:18
  • @Anthon - so then it's not a standard linux package? – slm Sep 9 '14 at 3:25
  • @slm I'm pretty sure I have it from the RedHat machines I used to have access to. It is a bash script, but I haven't used it for many years. It calls scsi_info which I don't have on my Ubuntu system at all. – Anthon Sep 9 '14 at 3:32
  • @slm correction, I have the source for scsi_info, comes with the RPM. Just not compiled/installed. – Anthon Sep 9 '14 at 3:34
