00000 SD card not supported, no local storing of data

Post by jdvoracek »

I am in the evaluation period after just installing on a Raspberry Pi 3B. The application runs and is uploading my old Peet Ultimeter 2100 data to Weather Underground, but I see the error message "00000 SD card not supported, no local storing of data". What does this mean and does it affect functionality? Thanks in advance!

It would mean the SD card you are using is not supported. In order to maintain ongoing integrity of the device and data there is a list of supported industrial SLC cards here https://www.meteobridge.com/wiki/index.php/Hardware

If the SD card is not supported, then why is the app running just fine? That 32 GB Sandisk SD card has worked fine in that Raspberry Pi with several other past installations, so it can't be a Pi issue. I'm just wondering why the meteobridge software is issuing that error. The URL you provided calls for a 1 or 2 GB card, and I can't imagine why a 32 GB card wouldn't work since they also say you can use larger if you can afford it. That must be from the days when such cards were expensive.

Consumer cards had a high failure rate hence the specific requirement to use industrial SLC cards,

As per the WiKi "To avoid SD card failure after a couple of months, Meteobridge enforces the use of one of the following industrial SLC cards:"

and

"When money is no issue you can also use versions of the above cards with greater capacity."

No problem using larger capacity version of the listed cards. Most systems don't require high capacity cards, it is up to you.

Thanks, that explains why the message!

Interesting though that the application still runs flawlessly on my consumer Sandisk. I'm not going to spend a lot of time, but a search for failure rates between consumer and industrial SD cards did not produce any objective publications, just opinions. Searching a few manufactures, Delkin gives a pretty typical sales pitch:

"Industrial SD cards can tolerate temperatures ranging from -40 degrees C to 85 degrees C, plus high levels of shock and vibration. They are used in applications that store critical data. They can also be found in devices used in extreme conditions, from transportation applications to automation and healthcare." Notice, no mention of failure rates.

That is, they may be more reliable in extreme environments, but again, no data. IMHO Meteobridge should let us decide which cards we use in equipment we purchase, but for 80 pounds to send data to wunderground along with 250,000 others, I may not purchase a license past the free evaluation period anyway.

Suppose it depends on how much one values their own data as that has the value not the hardware (as such), once cheap memory fails then so does the data, cheap storage/higher capacity is typically 2-3 or 4 bits per cell, where as SLC is 1 bit per cell with typically 100,000 P/E cycles, consumer grades a sub 10K down to 3K P/E so it stands to reason the write endurance of MLC & TLC is much less than SLC.

The failure rate of the original USB Intenso's in the MB was high and consistent ~ 2-3 months and obviously lacked data integrity, savvy uses were upgrading the Intenso's with SLC's which proved to be extremely good, those that continued to replace sub-standard not fit for purpose storage with more sub-standard storage continued to complain about permanently loosing data every few months hence the enforced use of proven SLC cards, basically protects users from themselves who continued to use storage that would fail then complain all their data was gone. These days storage failure in a MB is basically a non event.
