Micro SD card 32GB; issue?


Hello,
in order to boot a pi3, I wanted to use a Micro SD I had by hand (had worked on a pi4).
Result so far:
a) I have deleted all data by writing zero on the SD with the dd command (since I had errors with gparted and the recognized sized was only 1.8GB for a fat32)
b) I have then created a msdos partition table with gparted
c) tried to create a single partition with fat32 (8GB recognized)
d) so far done but with an error. see attachment.
Any advice is welcome..
a) throw that micro SD through the window (cost 10eur in online shop) .. or
b) spend more time with it for having working correctly (not sure where it is coming from.. SD adapter, SD card reader, SD card itself,..).
Any idea/comment is welcome.

dmesg log by connecting the SD adapter in an USB card reader:

Maybe try clearing the MBR first, give it a new one, then partition it, & put a filesystem on it.

Looking at its reported size, it looks like an image file was previously written to it, hence it's only reporting 1.8GB.

Example code to clear the MBR.
Code:
sudo dd if=/dev/zero of=/dev/<sdcard> bs=4M

What distribution were you planning on using?
Have you tried using dd to copy the image to the card yet?

Did you actually format the card with FAT32?

SDcards have very low writes. It sounds like it's going senile.

I would not bother with extensive writes, but when something beyond a simple fsck comes up, I'd order another. Because even if you get an image on (which you probably won't), how long would you trust it for?

I have done that dd when it was showing 1,8GB.
It was showing more GB after reformatting with gparted (FAT32).
But the card is now not recognized when I included it into an hub.

I was making all commands from Debian 64bits PC.
I want to use raspbian.
I made the dd to copy the image into the card but id did not boot.

You are right. I just ordered 2 new micro SD cards.
Its a pity because the card was used only a few time (however 2-3 years old with <10 probably unsafe shutdown.
So, now, I close that thread and it just confirm my impression since few months, SD cards booting a raspberry pi is an unstable thing (a copy of each install on a backup card should be made every time).

My RazPi is booting from an SSD. There's a firmware update that allows booting from USB. Even a usb key lasts far longer than sdcards. The expensive sdcards have better write spec, but a 2.5 inch drive runs fine from usb-3.x.

I haven't it tried it yet, but there is an SD card called 'Samsung Pro Endurance' that might be better than run of the mill SD cards. Thinking about popping for a few as there are situations where the location (size/power) precludes using a USB 3.0 external SSD. PI zeros come to mind too that don't have the USB option. Looking around my office I have 4 of my RPI-4s running off of 500GB T5 or T7 SSDs (ie. No SD Card installed, boot from USB SSD). I really like these Samsung SSDs even for general use. NOTE: only the 500GB drives. The 1TB and 2TB draw to much power and the PI will usually become unstable. I do wish the Raspaberry PI people thought about allowing more current into its USB sub-system. Of course if you add a powered USB hub then that problem goes away, but you no longer have a compact system and two power cords to deal with....
