e new disk that is connected by USB. Is
there some driver or package that I need to install to make this
work?
which file system is the old hdd formated in ntfs?
if so run in terminal
sudo apt install ntfs-3g
or use gparted to see the file system of the hdd
sudo apt install gparted

The old HDD is mostly ext3; there was also an
ext2 boot partition, and a swap partition. But
the new Debian shows nothing new in `df`. Is
there some other command I should use to probe for
whether Debian knows there's a HDD connected by USB?
I have a freshly installed Debian stable and I'm trying to read an
HDD from a previous machine. I put it into a disk enclosure that
connects to the new machine by USB and powered everything up, but the
stable Debian doesn't see the new disk that is connected by USB.

Take a look at /dev/disk/... where the names of the next level
of directories are self-explanatory. The files themselves
are all symlinks pointing to the kernel's device names.
Also /run/udev/data/b... where spinning rust disks are b8:N,
and N is a power of two for a disk, then N+1, N+2 etc for
the partitions. SSDs will be some other number like, say,
b259:0. The file contents are what udev has discovered.

"df" will ignore filesystems until they are mounted.
- Do you see anything in "blkid" when the USB enclosure is attached?
- Do you see anything in "journalctl -f" when you plug in the USB enclosure?

*headsmack* Thanks.

Nothing changes.

No output when I unplug it and replug it.

Now I realize that there may be an error LED blinking on the HDD.

The HDD may not be able to draw enough power. Plain USB A ports can only deliver 2.5W (500mA at 5V). You mentioned that the enclosure also has a
power cable. Is this another USB cable? Is it plugged into a USB port or a power adapter? Many USB power adapters can deliver more current.

What is the model of the HDD? What is its documented peak power draw?

Do you start "journalctl -f" as root (eg sudo)? It is rather
strange that nothing is logged at all. I would expect
at least some errors. It may be some issue with cables.
Have you tried other USB ports? USB3/USB2,
some ports may provide higher current.
Save output of of the following command to files when the enclosure is disconnected and connected and compare results
lsusb -vt | tee /tmp/disconnected.txt
lsusb -vt | tee /tmp/port1.txt
Try to connect the enclosure without the disk. It may appear
in lsusb output and may generate some journalctl logs.

You say, it is connected by USB. You then
should see the device with the command
lsusb
when the usb-connector is plugged in. However,
I have to be precise: You see the controller of
the case you put your HDD in, not the HDD itself!
But, if you can see it, first step is done.
For further examinations I suggest, to do the following commmand as root
tail -f /var/log/syslog
in console and then watch its output by plugging in and plugging off the USB case with the built in HDD.

Can you see the enclosure in the output of `lsusb`?
What is the output of `lsblk`?
What's the filesystem you expect to see? If there's a RAID
or LVM on that device, then you should start this first.

Power is coming from a transformer. The box says that the transformer delivers five watts/12 watts [I meant volts, of course] of power.

That's a clever idea, but it will be a while before I
can carefully unscrew the disk from the enclosure to try
it. First I need to try to restore from older backups.
I have no idea what steps you may try without disassembling the enclosure. Perhaps the issue is either data or power connectors inside.
HDD should generate specific noise when spinning up, then there should be something like clanks due to heads unloading/loading. Do you hear it?
The smallest 3.5" HDD (3 TB) for which I found official Seagate
documentation said that it used 8 watts while operating.
https://storedbits.com says a 7200 RPM hard drive would normally consume 20-25W for 5-10 seconds during startup. It will then idle at around
6-8 watts. The average power consumption during read/write tasks
will be around 8-12 watts, and the maximum can go up to 16 watts.
I would be surprised if the transformer for the enclosure
did not deliver sufficient power for the type of
drive that the enclosure is intended to enclose.
I have tried multiple USB jacks on the computer, of course.

For a 3,5" HDD you need a USB case with extra power. The
standard USB power is not enough for this needed power.
Most USB ports deliver about 50-70mA at 5V, so you
must use a case with an external power supply.
This is also needed for eSATA ports.
When I unplugged the transformer just now to store it, I
discovered that on the back it is labeled to output 12 volts
and 2.0 amps. That is 24 watts, which might not be enough to
spin up some hard drives. I'm not sure; it seems borderline.
As for the noise
of the heads, there was none, probably because the operating
system never saw the disk so never tried to read the disk.
However, head movement isn't always audible. 3½" and 5¼" drives aren't usually audible, although I've had a few very noisy 5¼ drives. And of
course SSDs are utterly silent.

I wonder how ancient drives you are using? Have there even been any mainstream 5 inch form factor HDDs manufactured since the Quantum
Bigfoot in the 1990s? I remember those drives being quite loud indeed.
