Tengo dos adaptadores SATA a USB idénticos (de Ugreen), uno de los cuales se desconecta y conecta constantemente o falla. No sucederá todas las veces, pero sucede la mayor parte del tiempo.
No creo que sea un problema con el adaptador porque funciona en otra máquina (ambas con Arch Linux actualizado).
dmesgpara conectar HDD de 2,5", montar, crear carpeta, desmontar, desconectar:
