I use the “dd” command fairly frequently, to put new versions of
SystemRescue on the USB stick I dedicate to that purpose, for example.
The command has been nicknamed the “data destroyer”, because while
doing sector-level copies as root, it can be all too easy to write to
the wrong device, and destroy an important filesystem.
The “lsblk” command can be handy for confirming which block device you
should be writing to, before pressing Enter on that fateful command.
There’s lots of information it can display, to help you identify the
right device. For example, a command like
lsblk -o NAME,SIZE,SERIAL,WWN,VENDOR,MODEL
shows a little tree display of devices and partitions in the first
column, followed by a lot of info you can use to identify what is
currently plugged in. I tried a couple of USB sticks, and they showed
amazingly long strings for their serial numbers. My SystemRescue stick
shows the vendor as “TOSHIBA” and the model as “TransMemory”.
Interestingly, both Western Digital and Seagate drives show the vendor
as “ATA”, though the model name begins with “WDC” for the one and “ST”
for the other. The SSD boot drives in both my main workstation and
laptop display blank for the vendor, but again the model field shows
some vendor-specific information.
