What the hell ... ?
Why does dd talk of filesystems ? I'd understand if it said "Permission
denied". The superuser isn't what he used to be.

Googling brings no insight: If it was an SD card, the advice would be to
blow air through the card reader.

Is any filesystem on /dev/sdd* mounted ?
If so: Does it help to unmount it before dd ?

Have a nice day :)
