I have a disk which was apparently put into PUIS mode with hdparm. As the disk does not spin up on power on automatically, I think I need to send it directly to the USB device (which is not even recognized as the device doesnt turn on)
I think this means the device is bricked but maybe someone has a solution? The disk is a Western Digital My Passport 4TB with a WD Blue inside, model number WD40NMZW-11GX6S1 from 2018
