In the last episode my old MyCloud died (front led is steady red) and I wasn’t able to connecto to it. New network cable didn’t work. Reset attempts, short and long, didn’t do anything - the led remained solid red. I assumed - and hoped - this was a bad controller and the HDD is still intact. So I got a new MyCloud, connected it successfully and now I want to copy to it the content of the old one. I removed the HDD from the old MyCloud box and, using a SATA-to-USB cable connected it to the USB port of the new MyCloud, which couldn’t read it (front led went red until I disconnected it). Then I fired up my Linux (mint) installation which identified the disk as /dev/sdb. I tried to mount it using this:
sudo mkdir -p /media/usb
sudo mount -t ext4 -o defaults /dev/sdb /media/usb
and got this error:
mount: wrong fs type, bad option, bad superblock on /deb/sdb, missing codepage or helper program, or other error
What does that mean? How even can I find out if the old HDD is OK?
