Default WD My Passport problem

Can anyone tell me what is going on here and maybe suggest a cure.
Long explanation follows!
I have for the last 6 months used a 500GB WD My Passport drive with all my
music on it 212GB, 3,479Folders, 41,546Files in my car with no problems, I
recently took it out to add new music, but when I put it back in the car I
got the message 'No music or picture files'
So I reformatted the drive ExFAT, Folders and Files are named thus:
folders A, B, C, etc. with folder with Artist name within and Album names
within that and MP3s within that.
I added a few folders (A & XYZ)put it in the car and all the music was
seen and could be played, so took it back inside added C, D, & E but then
got the message 'No music or picture files' again.
Tried all that again with the same results, then deleted those extra
folders, tried it again and it was now seen, there seems to be some kind
of limit where there was not previously.
How can I have all my music in the car with me again?

Why wouldn't you Google the car make and model and
its infotainment system, to learn of its quirks ?

It sounds like the car is adding files as "markers"
to the file system. CHKDSK on the Windows end is
removing something it doesn't like, then the car
notices when the drive comes back.

If your car system has a "quirk", Google should
be full of the details.

But how come it's only just started happening? surely it would have
happened on previous occasions I've added Folders/Files, I'm struggling to
work out what is different to last week.

Wow, you're banging the platters and heads around on a hard disk while
driving around in your car? Yes, they're portable but that means use
one place, move to another place, and use there, but not during
transport. Your high-school physics teacher didn't explain how
grypscopes work? They never had you hold the axle on a bicycle wheel,
spin it up, and had you move the bicycle wheel's axle? See
https://www.youtube.com/results?sear...um+gyrosc ope.
Didn't they teach you about momentum? And you don't the heads in a hard
disk are supposed to fly but a few nanometers above the surface of the
platters (fly height) which is far less than the size of a dust particle
or even your fingerprint?

When spinning (or even during spin up and spin down), the hard disk
should be stationery. Some will survive a couple G's in force but not
the jolting from driving your car over pot holes and gyroscopic effect
will put extra wear on its bearing during turning of the car. Physical
trauma kills hard disks. Even laptop users know their HDDs shouldn't be
spinning when moving the laptop. Shutting the lid powers down the HDD
so it is NOT spinning during transport.

It's not only the jarring and gyroscopics while driving but heat also
kills them. Do you keep the HDD in your pocket upon entering your
vehicle, start the vehicle and put on the A/C (in summer) or heat (in
winter) until the inside temp of the car is within the "operating
temperating range" of the portable HDD before you plug it into power
(USB port supplied or external power source)? Do you leave the portable
HDD in your car when you leave your car? Do you leave it where the sun
can get at it or leave your windows rolled up in summer? How are you
going to keep it warm and within operating temperature range upon
returning to your car that's been sitting out in the winter for hours
with the portable HDD inside?

Your car gets cold. Your car gets hot. HDDs have an operating
temperature range but that means letting the HDD warm up or cool down to
get in that temperature range BEFORE powering it up. Jobbers building
car PCs are vexed with high failure rates of HDDs. Also, the WD My
Passport drives are NOT ruggedized drives. I couldn't even find a
G-force rating for them. Some "ruggedized" drives claim mil-spec drop
ratings but that's just for one drop, not the constant jolting in a car
driving over the road. Velco or otherwise rigidly affix your smartphone
to your car's dash (so the phone is vertical) and get a g-force app,
preferrably with a time graph to keep your eyes OFF the phone while you
are driving, to show you how many G's are those potholes, speedbumps, or
whatever you encounter while driving. From what I've seen of the specs
for ruggedized hard disk, they are to survive abuse when NOT in use.

https://www.wdc.com/content/dam/wdc/...779-705155.pdf
Page 4:
- Do not jolt the drive.
- Do not move the drive during activity. (*)
(*) Means when the drive is active (powered and spinning).

You don't use HDDs when your car is moving. When the car is moving, you
only transport an inactive HDD. Nor do you store HDDs in your car.

Run "chkdsk drive /r" on that portable HDD to mask out any bad sectors
that have cropped up due to your abuse of the portable HDD.

Did you check the specs on your "car player" to determine what file
systems (FAT, NTFS, exFAT, other) that it supports? Within each format,
the player may still have its own limit on the size of a file, the size
of a partition, how many partitions are supported, and how many files
can be within a folder. The firmware in hardware players is not
equivalent to what a general-purpose OS (Windows, Linux) can handle.

Copy the files off your USB hard disk onto a USB flash drive and use the
USB flash drive in your car. Even those, however, have an operating
temperature range but they are not susceptible to gyroscopic bearing
wear or subject to momentum (beyond the physical construction of the
flash drive but by then your car and you aren't in such good shape,
either).

Probably because the car system firmware has a limit on the number of
folders and/or files it can handle and you have now exceeded the limit.
With 41,000 tunes I doubt you will miss a few if you try deleting them.

I had already considered a limit but I am putting on nowhere near what it
was previously able to handle, as I said in my original post, it was able
to see my whole collection, I have now tried another drive and the results
are the same so I suspect a fault in the car system (it is a late 2015
Mercedes c63)
Of course I've tried googling, but putting the words 'hard drive' into a
search are not productive as it throws up 1,000s of unrelated posts.
thanks for your suggestions but I've about given up and am using 2 memory
stick instead, not all my music but enough.
