I have an external usb hdd which is automatically auto-mounted. 

[$] udisksctl status                                                                                                               
MODEL                     REVISION  SERIAL               DEVICE
--------------------------------------------------------------------------
ST1000DM003-9YN162        CC4B      S1DC5K41             sda     
HL-DT-ST DVDRAM GH24NS95  RN01      KASD5942243          sr0     
ST2000LM003 HN-M201RAD    2BC10007  S34RJ9AFC80519       sdb

Now as can be seen /dev/sda is my internal HDD while sdb is the external usb hdd. Now I saw A clever way to defragment a FAT filesystem?

I tried to run the model number via search-engine and saw that the same model number is given to Samsung as well. I recalled that Seagate had bought Samsung in 2k11 and I bought this hdd a year or two down the road.

Now on the external case cover it says Seagate so I have to presume/assume it is a Seagate and because it is rectangular in shape, I am assuming it is the old/regular magnetic arm-based hdd. But is there anyway to confirm the same in Debian ?

If hdparm can talk to the drive, and the drive supports ATA-9, you'll see a line in the output of hdparm -I with the appropriate info:

        Nominal Media Rotation Rate: 7200

(for a 7200 RPM rotating drive)

        Nominal Media Rotation Rate: Solid State Device

(for a solid state device).
