The "smartctl" command with a parameter of "sda3"
gives me this:
bash.7[~]: smartctl -a /dev/sda3

And if you look at the label of your hard drive, you'll find that data
printed on it somewhere. Conversely, if it's difficult to access the
label on your new drive, look at your old removed drive, and see that
This looks like the output I was getting last spring, when the old
hard drive was dying. The current drive, a new drive, was installed
at that time (late June). It's as if smartctl is at least in part
simply re-displaying results from the last run I did on the old drive
It'll just be similar. I seriously doubt that SMART can show cached
data, somehow. I've only ever seen it produce data that's come *from*
a drive, there and then. Try asking it to poll a non-existent hard
drive (e.g. sdb), and you'll see what happens.
There can be a lot of scary looking numbers in the data, and you can
also get a bad new drive. If you have bad cooling, that's bad for
drives. If your cabling is mangled, that can produce data errors (SATA
cabling should never be folded or kinked, if you need to get it out of
the way of things, use gentle loops).

Shows the drive has been on for 2,614 hours. That would be 109 days,
if it had been left on permanently. If your computer is only on a
fraction of the day, do a bit of math to see if it fits your
Also, the output is basically the same whether the smartctl
is "sda", "sda3", or "sd?".
SMART data is for the whole drive.

Moments after you've soldered the wires onto the plug just perfectly,
you'll realise that you forgot to put the backshell on.
