I believe this is of possible interest to others here: Most newer USB enclosures now support SCSI STOP/START commands. But.. the Western Digital 2.5" mobile USB2 enclosures (SATA inside) appear to also support the SCSI-ATA-Command-Passthru protocol. These are the first ones I have seen here that do this. So, things like "hdparm -I /dev/sdb" work without fuss on an external USB drive when used with these enclosures. As does setting automatic spin-down with "hdparm -S".

Model: WD-250XMS-00 (with 250GB drive inside, removeable). USB info: 1058:0702 Western Digital Technologies, Inc. Bridge chip by InitIO: INIC-1606L
.. Mmm.. I also have two NexStar-3 2.5" USB/eSata enclosures here, but they are not identical on the inside. The one with an InitIO INIC-1610L chip does *not* support SAT, but the second one with an InitIO INIC-1611L chip *does* work with SAT! Good to see these chips getting out there now, as it allows external storage to be spun-down much of the time when only rarely needed -- keeps the drives from cooking the rest of the time.
