Hi, I am also experiencing the same issue. I am using the lastest firmware version from Oleg on my WL-HDD and for some reason cannot see the external HDD.
I look into the /dev/ directory and sub-directories but cannot see the USD HDD (was looking for a SCSI directory or something like that).
I checked the syslogs and it doesn't show the external HDD being mounted at anytime.
Would really appreciate some help on this.
Cheers
