Description Mantas Mikulėnas 2016-05-20 17:17:51 UTC 
I have a Hitachi Deskstar external (USB) disk, which supports SAT well enough to work with smartmontools but is not recognized by libatasmart. 

It seems the problem is with disk_command(SK_ATA_COMMAND_IDENTIFY_DEVICE, …), which returns all NULs. However, sg_sat_identify from sg3_utils works fine.
