 Hi.
 
 Not all eSATA cables and devices are equally good. Could you try to
 repeat the test after limiting eSATA speed down to 1.5 Gbps? You can do
 it by adding to /boot/loader.conf line:
 hint.ahcich.7.sata_rev=1
 
 Also, if you boot kernel with verbose logging, it may report something
 more about error into messages.
