Hi @vBit,  
Happy to see that we aren’t the only one to get that result.  
What kind of mSD card is it? Because depending on four aspects I think which are manufacturer, transfer speed, card class and memory size, the mangOh Red will react differently.  
I have tried with SanDisk Ultra Plus microSDHC UHS-I 16 Go class A1 with speed up to 98 MB/s and I’ve got the same error like you. I managed to change the format of mSD in ext4 (add support for the mangOH too), exFAT and FAT32 and till the same. With or without IoT. See also [Using MicroSD MangOH Red](https://mangoh.discourse.group/t/using-microsd-mangoh-red/1295/4?u=alex1) and [https://mangoh.discourse.group/t/micro-sd-support-on-mangoh/91/11](https://mangoh.discourse.group/t/micro-sd-support-on-mangoh/91/11)  
I post that.

```

I suspect mangOhRed may accept only mSD cards with 8 Go capacity and not so high speed, is that right @asyal? Or is it just software?

But it’s still incomprehensible that mSD provided in the kit doesn’t work.

Thanks for any help!
