Easiest thing is to boot a linux live CD or live USB or install virtual
box and have a linux virtual machine. Then you aren't handicapped by
Microsofts inadequacies.

Easier to just use an rPi.

I did use to use VirtualBox, but switched to Hyper-V when I need my VMs
to boot with the host booting, there was a cludgy way to do it in
VirtualBox, but it was a standard feature with Hyper-V.

Anyway, I pretty much gave up using traditional VMs when WSL 2 appeared.
That enabled me to run Linux Docker machines and I had the rPi if I
required a proper Linux machine, for stuff like reading Ext4. It would
be nice to read Ext4 SD cards in WSL2, but I'm not going to run out and
buy a new machine, to get W11.

Anyway, I was interested in the RPi Imager/headless install Andy Burns
was talking about. After some fannying around, I re-remembered that the
SD card boot partition is FAT anyway, so I didn't need Ext4 to see what
was going on.

The RPi imager drops a shell script in the boot partition, firstrun.sh.

SSH worked for me with both password authentication and with public-key
only authentication. A little bit irritating that the password
authentication didn't copy a public key across.

However, all in all, It is nice to be able to do a WIFI headless instal.

Don't know. The Windows machines here are all Win10 Pro or Win10
Enterprise. WSL and/or WSL2 install fine on W10. Try it and see if it
works. If it doesn't automount, you just have to manually mount it with
the right fstype, not the end of the world.

You can probably use Cygwin to achieve the same end but WSL/WSL2 seem to
install with less effort IMHO.

Mount what exactly?

AIUI, The hypervisor on Windows (e.g. Hyper-V, Virtual Box) has tended
to get devices handed to it by Windows. If Windows cannot handle a
device, such as an Ext4 USB, Windows will not make the device available
to the hypervisor.

Now, some hypervisors enable hardware passthru, which may make things
such as the USB device directly available to the VM. I've played with
this in the past and generally found it to be a pain. A promise that it
will work, that suddenly vanishes when some arcane gotcha brings the
whole plan grinding to a halt.

In this case, the WSL2 gotcha was I need a specific build which I don't
have, and it is far from obvious that I could have even if I spent hours
researching it.

ISTR the command used was something like

wsl --mount \\.\PHYSICALDRIVE3

I know we did this at work to write files to an ext4 partition on an
SDcard for an RPi Zero being used to do some USB gadget software
debugging. We don't have any Win11 machines. This was during lockdown
and someone would have to had to get permission to visit the office, get
their keycard enabled, driven to the office, put the card in many of the
Linux lab machines, copy the file and drive back. Which was why WSL was
used. I'll ask the guy who did it how he did it next time I see him.

I use lots and lots of Virtualbox VMs (running Linux and Windows) on a
Windows 2019 server and we have the VMs accessing the Windows Server USB
and PCI root complex hardware without any issue.

Good!
The handiest holder I found is this:
https://www.amazon.com/Bandc-Storage-Holder-Memory-Included/dp/B018RUWK98/
A file folder label fits perfectly in the center.

> Thats not the problem.

One fellow suggested a "readme" file on the SD card itself
so they're kinda self-identifying.

When possible, I use a descriptive label on the file system
despite the 11 characters limit.

The bottom line:
I agree that they're too small to label at home.
Even permanent markers rub off over time.
Kinda like trying to mark keys.

I have had good success using a paint pen. Sharpie for example makes
paint versions of their markers. The tip is fine enough to write an
identifier on the chip and will not rub off easily.

Look for "paint pen fine tip"
Amazon has dozens of examples. Not very expensive either.

1) That won't help me much when I have a few micro-SD cards laying on the
table in front of me. Or one micro-SD card and several SD card adapters to
put it in.

2) I can put a file on the card using an RPi, but I than can't read it under
Windows - and vice-versa. Making it a lot less usefull.

:-) Although my fine-motor skills agree with you, a few people have
suggested just that. And one of them even posted an image of his, very
readable, handwring.

Also, I and at least one other person here have used a Dymo LetraTag to
create a label (with two lines with upto 8 chars per line) which, after a
bit of trimming, fit neatly on the front of a Micro-SD card.

IOW, Problem solved.

Othello,

Thank you.

Alas, I've already tried to use something of the kind (a "silver" pen), but
that both didn't really want to stick (on the smooth-and-shiny backside) and
(thus?) rubbed/broke off when even normally used.

I've found a solution in using a literal label. Which solved a number of
problems at the same time : I don't need to try to write anything that
small, it comes with its own background (allowing me to put it on the
front), and its even removable.

I have an USB card reader, can be used on your running PI to check any cards.

Jan,

Yes, you can - but as mentioned only the "boot" and "root" partitions are
auto-mounted when its inserted, both the Windows "W95" FAT16 and FAT32
partitions stay invisible.

Under Windows I can not see the Linux "boot" and "root" partitions at all,
and only one of the "W95" FAT16 and FAT32 partitions (not yet sure which
one, likely the first, FAT16 one).

And although I'm, as written, quite sure that the RPi can access the "W95"
FAT16 and/or FAT32 partitions, I'm not at all sure how I can do that in an
easy fashion (a shell script perhaps?).

I might try to figure it out some day, but currently I'm happy with being
able to physically label it.

Find out their labels, and edit /etc/mnttab to mount them at boot time.
Or find out their labels and write a one line script to mount them under
user control.

If you have a GUI on the pi they should be visible to whatever partition
editor you have.

And should be mountable from there also

Yea, my error perhaps
Many many years ago I bought a book on Unix
Then much later when I found a CD with SLS Linux (maybe around 1998 or so?)
it took me about an hour to get into it and never left Unix again
FIle structure, shells, basic commands is something you SHOULD
really learn when using a raspberry IMO to get out of it what's in there.
I hardly ever use the GUI other than for programs I wrote that use one
and webbrowser
Replaced the whatever GUI that came with the latest raspbian release with fvwm and xfm
and do everything (almost) from the command line.
9 virtual screens, easy to switch between those with the keyboard or mouse,
dmesg
mount unmount
ls
cd
grep
gcc!!
So many things that make using a raspberry or Unix system so nice.

I started using QR codes printed on a labelling machine - that can
point to either the card's .local address if it's something like
Homebridge or pi-hole. Extendable idea to point to a locally-hosted
more descriptive web page maybe.

Obviously the amount of data you can encode on what is probably a 9mm
square code is limited.

Check out "Linux Reader" from www.diskinternals.com

The free version allows you to freely mount & examine Linux formatted (and others) partitions from Windows (read only).

Although that could certainly work, its also means that you would always
need the QR code scanning hardware and a computer pulling up the associated
information active/running. Not really something I would be doing for a
once-in-a-while (might be weeks apart) situations.

Thank you for the suggestion though.

Thanks. As it so happens I, while looking for something simpler than WSL,
found it too. Might even try to use it. :-)

On the other hand, the RPi /should/ be able to access a W95 FAT16/32
partition without the need of any additional software ...

Your phone may already have the "QR scanning hardware" and you could keep the

It is, assuming the partition is in good order. I just do:

sudo mount /dev/sda1 /mnt

(assuming the USB drive is sda, which it probably is if you booted from SD
card)

and then poke around in /mnt to see what's there. Then:

sudo umount /mnt

Rinse and repeat for the remaining sda2, sda3, etc.

That works irrespective of distro, desktop environment, fancy GUI
automounter, etc etc.

If it fails to detect the partition type it suggests something is quite
wrong with the partition, as most common formats can be autodetected.

Neither of which I have. :-)

> The QR code could be just the URL.

I've just taken a peek at the different QR types. The smallest one, "Micro
QR" has 35 "numerical characters". I'm not sure if those are automatically
translated to characters / a string.

But assuming those "numerical characters" contain 4 bits a piece and the
character encoding would use 6 bits per char you would be left with about 23
chars - which is enough for an URL.

The biggest problem is that even that "Micro QR" is a 15x15 grid, making, on
a 9x9mm surface, its squares less than a mm across ...

Thanks. I guessed as much, but had nothing to go on.

And I read somewhere I had to create that "mnt" directory first ? You do
not seem to do so.

And a question : do you know wat happens when you (try to) eject the USB
dongle containing the uSD card you just mounted a partition of ? I would
not like to have either the boot uSD or the mounted one trashed.

Most distros already have an empty /mnt directory there, ready for something
to be mounted.

If you use the desktop environment 'eject' button, it may or may not remove
the mountpoints. In the above it's done as root, and a regular user won't
be able to unmount something mounted by root, so the eject complains
something is still using the device.

If you 'sudo umount' it first, everything should be fine.

You can also just forcibly do 'sudo umount /dev/sda1; sudo umount /dev/sda2;
....' to make sure everything is unmounted first, irrespective of whatever
the desktop does.

If in doubt, 'sync' to ensure anything unwritten is flushed to the disc before
removing it.

It almost certainly can. Certainly my desktop can see everything on my
PIs SD card - or could when it was inserted to build it. The PI doesn't
mount more than the boot and root partitions though by default.

If you want it to, edit /etc/mnttab

/mnt may or may not be created by default - I think /media/<username> is
often used to mount removable drives at least on my desktop linux

This is all superstructure though - as root you can mount a drive
partition any damn where you please, even to the point of screwing up
your machine if e.g. you decide to mount it over /bin!!!!

USB stick "root" forgot to take with him. Oh well. I guess nothing a
