How to see disk details like manufacturer in Linux
@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.
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 🙂
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.
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/
Use a recent kernel maybe, what distro are you using? try dmesg | less , should see the disks get probed.
@jennifer: cat /sys/block/sd?/device/
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.
lsblk (List Block)
You can use lsblk command:
$ lsblk -o NAME,FSTYPE,LABEL,MOUNTPOINT,SIZE,MODEL 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)
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):
/sys/class/scsi_device/. /device/model cat /sys/class/scsi_device/0\:0\:0\:0/device/
(The backslashes next to zeros are for escaping special char : .)
lsblk (List blocks) gives a list with device, size, type and mount_point

I noticed that my Ubuntu is lagging EXTREMELY badly but only the first time I do things after what I did gets loaded into RAM the lag stops totally. I ran some tests and I guess one of my laptop hard drives is borked. Im assuming that I have to replace the drive, is there some command I can issue to see the exact specs on the drive so I can then buy it online? I don’t want to have to open up the laptop, find the specs. Then open it again when the new drive arrives.
Or is there another cool hacky command or way to partition my drive to avoid using the bad spots? A while ago when my drive failed I mounted it useing an alternative superblock and this worked and still does i guess..
I found the hacky solution I wanted. I ran the command «badblocks /dev/sda1» and then noticed they were all near the front of the drive. So I created an unallocated partition at the front of the drive consisting of 50% of the total size. I then tested the second half of the drive! AND WALAAAAAAAA. IT WORKED. Im going to buy a new drive anyway but this process taught me alot 🙂

smartctl command from smartmontools package is what you want for that

SMART support is: Enabled lshw -class disk -class storage Thanks I hope this helps someone but the first answer was PERFECT so im not even bothering with this, do you know if I can somehow use only part of my hard drive? The hole thing still works but super slow. I know nothing of hardware but maybe there is a way to say only use the good part of the hard drive? Maybe when hard drives go bad only certain portions go bad?
