List what each sd is

Question

On Linux I know that sda, sdb, and sdh are hard drives, but I don't know what is sdc, sdd, sde, sdf and sdg are. Some of them are (I think) empty and some of them, the kernel tries to make them spinning without success

Is there a command to know what there is behind those?

$ lsblk -l | grep sd
sda         8:0    0   120G  0 disk 
sda2        8:2    0   110M  0 part /home/user/sda2
sda4        8:4    0   100M  0 part 
sda7        8:7    0    10G  0 part /home/user/sda7
sda8        8:8    0    10G  0 part /home/user/sda8
sdb         8:16   0    60T  0 disk 
sdb1        8:17   0    60T  0 part /home/user/sdb1
sdc         8:32   1     0B  0 disk 
sdd         8:48   1     0B  0 disk 
sde         8:64   1     0B  0 disk 
sdf         8:80   1     0B  0 disk 
sdg         8:96   1     0B  0 disk 
sdh         8:112  0    70G  0 disk 
sdh1        8:113  0    40G  0 part /home/user/sdh1
sdh2        8:114  0    30G  0 part /home/user/sdh2

$ grep . /sys/block/sd*/device/model

Try with `lsblk -l | grep sd`. Eventually, add the result to the question, [edit] it and format the copied text with the code tool `{}`. — schrodingerscatcuriosity, Jul 12 '21 at 16:31
`cat /sys/block/sda/device/model` will tell you the model string of the `sda` device if that is what you are asking. You can use `grep . /sys/block/sd*/device/model` to see all of them with one command. — icarus, Jul 12 '21 at 16:38
What's the difference with `cat /sys/block/sd*/device/model`? — aaa, Jul 12 '21 at 16:55
`cat` will just output the contents, `grep ^` or `grep .` will prefix each line with the filename so you know what goes with what. `grep .` will ignore empty lines. — icarus, Jul 12 '21 at 18:14

I use inxi for this, it gives a convenient report that is fairly complete depending on the verbosity levels selected (-x, -xx, -xxx, or -a). Also, there are other drive types than sd, there's hd, fio, nvme, mmcblk, a few others. Where this data comes from varies depending on if it's GNU/Linux or BSD, some is generated internally (like vendors), some comes from the system.

Basic report (-d adds optical drives to the -D drive report, -z filters sensitive info out, -y makes report 80 columns wide):

The disks are unmounted, if you want view information then to use:

lsblk -o MODEL,TRAN,VENDOR,NAME,FSTYPE,LABEL,MOUNTPOINT,SIZE,MAJ:MIN,TYPE,STATE,SUBSYSTEMS

or

sudo lshw -class disk
