How can be so diferent that the one make with esata?
That's because your enclosure is emulating IDENTIFY command when
attached via SATA. It's emulating USB mass storage device when
connected via USB but your enclosure is good enough to implement ATA
command passthrough and as hdparm issues IDENTIFY using command
passthrough, it gets to the actual drive and returns the result directly.

Hey, way cool.. that's the first enclosure I've heard of "in the wild"
that implements ATA command passthru.
Gotta remember that one ("Seagate FreeAgent Pro" USB/eSATA enclosure).
