Looks like the problem is in the communication between the drive's
enclosure and your computer. The drive is probably just fine.

Depends on the USB<->SATA bridge used in the enclosure. Some support
SMART and some part of hdparm as well (e.g. set timeout for spin-down);
the only problem is that it's terribly difficult to know which ones do
and which ones don't, without actually buying them and trying them out,
because such details are basically never documented.
