Can I see what HDD I have installed?

Question

I use lspci for pci devices and lsusb to list the usb hardware devices, is there something similar to list my SATA HDD model ?

Answer 1

You can use hdparm to retrieve information about your hard drives, eg.,

hdparm -I /dev/sda

Where I, according to the man page:

-I     Request  identification  info  directly  from the 
drive, which is displayed in a new expanded format with considerably
 more detail than with the older -i option.

For SCSI drives, use sdparm.

Answer 2

hdparm usually with the -i or -I options should give you rather exhaustive information.

Answer 3

smartctl -a will even tell you the serial numbers of the disks.

Answer 4

I know you've already accepted an answer but I thought I'd add something for posterity:

If you need to know what block devices are seen by the kernel /sys/block/* will have the listing. You'll have to sift through that list to filter out the virtual devices that just present to the system as block devices.

Most modern distributions will also list the devices by their path (for example, if they're SAN, which HBA and what the WWPN they're coming from, etc) if you do ls -l /dev/disk/by-path:

[root@dfletcher ~]# ls -l /dev/disk/by-path

In the last line pci-0000:1a:00.1-fc-0x5006016d3ee0025f:0x001500000000000 can be read left to right as: coming off the pci bus, from device at PCI address 1a:00.1, fibre channel protocol(fc), with the remote WWPN of 0x5006016d3ee0025f. The last number is a LUN id that the HBA has assigned to that LUN, but I've never found it useful.

Answer 5

If you don't have hdparm and can't install it then you can try dmesg | grep -i ata to obtain some information about your hard disks.
