What kind of error is this?

[Hey]

Colleagues, what is this error and where does it come from? I recorded the image on an SD card with the minimum version of DietPi - Odroid C2 and this error appears during the first run and later after restarting.

I/O errors indicates a failing card, wrong format or connectivity issues (it’s not placed right in the slot).

You can try to reflash it. If this does not help, try another tool for flashing (what tool did you use in the first place?)

[Hey]

I used SD Formater to format the card, and later, if I’m not mistaken, it was AOMEI Partition Assistant. I loaded 3 different firmwares onto the card and similar results resulted in some errors. I replaced the card and it went quickly everything works.

I also have a question because Odroid C2 is to be used as a NAS server and I noticed that when I connect an SSD drive for data storage, after restarting the device wants to boot from USB, i.e. SSD drive, and the NAS software does not work from the SD card. .Does anyone know how to change it to boot from the SD card?

Are there any data on the SSD?

[Hey]

There was only music in FLAC format and no software data. The disk was removed from another NAS device without formatting and the directory to be shared over the network was added to OpenMediaVault in the program.

hmm not sure why the SSD is taken. Maybe @MichaIng has an idea.
