Pi 5 second SD card bricked

[go4it2th (Candid Aeby)]

Update to 14.2 failed and my interface wasn’t accessible anymore. As I have a daily backup no big problem. Wrong, the problem exists after flashing the card with Raspberry Pi Imager 1.8.5. So I tried to format the SD card with every possible tool like Windows diskpart, Apple disk utility, SD Card formatter and so on… I just get a new card.

Is there any way to rescue the cards with all those partations? It’s not even 10$ each but still unnecessary.

$10 doesn’t sound like you’re buying high endurance SD cards, which you really should if you want to stick with the SD card format.

pi5 supports SSD. Get one. Using card is asking for problems.

high endurance SD cards

That “endurance” (or durable) type cards are the wrong ones for this use case.

Would a cheap $15 ssd like this be good for a rpi?

Completely different use case and you misinterpreted your mileage to be valid for a complete different task (which is it not!) If you use such cards for continuous recording like the seller expects (“Full HD (1920x1080) video content recorded at 26 Mbps”) the write amplification factor will be probably always be 1. So for every (m)byte requested from the OS to be written to storage also exactly one (m)byte is actually written to flash. That’s great b…

Do you mistake them for (expensive) “industrial” ones by chance?

Home Assistant OS Release 8

But these “write intensive” tasks are “big junks” or sequential writes (like a video or images). This types of writing will probably have a WAF (write amplification factor) close to 1 because they certainly always will write full “pages” (the host writes will very much equal the flash writes). So this is the perfect scenario for a flash storage as there is virtually no write amplification and you will get the maximum lifetime for your flash storage. If you look at the details for this card: Mi…

The best, when using SD cards, is (like the ha docs tell us) to use A1/A2 type cards.

Micro SD Card.

• Ideally get one that is Application Class 2. Check for the label A2 on the card. Application Class 2 cards perform better especially on small read and write operations and are better suited to host applications.
• Make sure to use a card that provides at least 32 GB.

The industrial type doesn’t make sense IMHO as for that price you get a proper ssd from one of the few flash manufactures left

Next best thing with SD cards is oversizing to have as many “fresh” cells available as possible which really leads to longer endurance (with the same amounts of writes)

Thanks to all who answered.

My question is how do I format a SD Card that was used in a Pi5 for Home Assistant. I wouldn’t mind to replace a broken card with a new one. The card was working, the update failed.

If I used an SSD for the same application and I can’t format the SSD the damage to my walet would be bigger.

If you can’t even format the old card it’s probably grid locked (read only) which indicates EOL

I replaced the card and I bought a spare card. You never know… but when you’re ready you not gonna need it

You might sharing make, model, class and size?

Fingers crossed you didn’t went for a “endurance” (instead of class A) type falsely advertised before by @robertklep

I have the SanDisk Ultra Class10, UHS-1, 32GB. SanDisk sell them here in Thailand normally for 8 USD.

SanDisk Ultra Class10, UHS-1, 32GB.

SanDisk (now owned by western digital) is a well known brand and one of the few last flash manufacturers (like Samsung).
Dir you managed to get a A1 or A2 to class card which should offer best performance for I/I intensive tasks (what happens when running HaOS)?
32GB seems like the smallest available size today, often you get the double (64GB) for only one or two bucks more - which would be definitely worth it as it might just double the lifetime as explained earlier
