I used to have an external HDD connected to my RPi2, but after I updated/rebooted today, I am not able to mount my external HDD (WD Elements 500GB) again. The HDD is ext4 formatted, if this matters in any way.
The HDD is not shown with lsblk nor lsusb:
$this->bbcode_second_pass_code('', '
$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
mmcblk0 179:0 0 14.9G 0 disk
├─mmcblk0p1 179:1 0 100M 0 part /boot
└─mmcblk0p2 179:2 0 14.8G 0 part /
$ lsusb

')
I tested the HDD on my Laptop (running archlinux x86) and is working there.
I dont know what I could try next...please help
Many thanks in advance,
