dd: /dev/rsd0d: Device not configured (RPi4)

[Ramiro Aceves <ea1abz%gmail.com@localhost>]

Hi,

I have a RPi4 working fine for a long time. USB devices work, I have 
tested a keyboard, RTL dongle receiver, USB WEBCam...

But today I tried to flash a 125GB SD card using a SanDisk USB dongle 
card reader connected to one of the USB RPi4 ports:

fdisk seems to work cause I used it to delete previous partitions:

Thanks.

dd commands work just fine in my Thinkpad x260 running also NetBSD 10.1. 
I ended flashing the SD card on the computer because it surprisingly 
failed on the RPi4.

Am I missing something?

Thanks so much in advance.
Ramiro.
