As soon as I plug my external hdd in a usb port, it makes a sound similar to the one in the video mentioned below for ~90 seconds.
Afterwards it stops making it, and gets recognised as a CD drive on my computer. Weird thing is, that it shows up fine alongside my hard disk on device management:
Results of the DLGDIAG test:
Serial number matches the one on the HDD. Only problem being capacity not showing up, since it’s not recognisable, and impossible for me to test it.
Tested in all 3 USB ports of my laptop (1x 3.0, 2x 2.0)
Also showed an “error performing inpage operation” before it wasn’t recognised at all, and the drive seemed to be recognisable, since I could see the WD Unlocker image, but apparently I couldn’t unlock it. It actually took me a while till I saw this message. Also showed me an I/O device error at times.
