The Power Managing Unit (PMU) of the MacBook Pro seems to keep powering the USB-bus. +Host computer goes to sleep -> Disk spins down.+ +Host computer unmounts drive -> Disk spins down.+ +10 min no disk access -> Disk spins down.+ *Suddenly all energy saving features work as expected!*

IV) I disconnect all cables, *remove the jumper shunt, and again connect* the enclosure to the Mac Book Pro, Mid 2009.

Mac OS X tells me "Device not recognized? Format/Eject?". It seems that the enclosure chipset does not support PUIS. The disk does not spin up, contrary to my hopeful expectation. Then I connect it through USB to my mother's MacBook Pro, 15 inch, Mid 2009 (MC118LL/A) running Mac OS X 10.6.2. III) As an experiment to get the sleep mode working on the enclosure, I set a *jumper shunt on the pins 3 and 4 of the WD10EADS-00L5B1 hard disk to enable PUIS (Power up in standby)* and then mount the disk in the enclosure. +2) Wake your enclosure by pressing the button.+ +Computer goes to sleep -> Disk spins down, which is fine, BUT when waking the computer again, the enclosure remains in sleep, which results in an improper disconnection! If files where open, this could even mean data loss/corruption.

II) Enclosure connected to my girlfriend's *IBM ThinkPad* running Windows XP SP2 *via USB 2.0*. In reality this didn't work because the previous step failed in all its 3 variants.+ +3) Only in theory: Power on enclosure again BEFORE waking computer, so that the disk is present to the computer as before. +Sadly, NONE of the methods worked, as all caused a wake event on the computer, which then complained that the disk was disconnected improperly.+
+b) Power of enclosure by disconnecting the power-cable.+
+a) Power of enclosure by holding button for 3 seconds.+ +1) Put computer to sleep, disk continues spinning.+ +Computer goes to sleep -> Disk continues spinning -> WRONG! It is a) a waste of energy and b) unnecessary disk operation hours also wear off the disk over time. Ib) Enclosure connected to my *Apple MacBook Pro, 15 inch, Core 2 Duo, Late 2006 (MA609LL)* running Mac OS X 10.5.7 *via USB 2.0*. +3) Power on enclosure again BEFORE waking computer, so that the disk is present to the computer as before.+ +None of the versions wakes the computer -> Correct!+ (Maybe circuit board and/or power-supply-unit still consume energy, I am not sure.)+ +b) Power of enclosure by holding button for 3 seconds.
+a) Power of enclosure by disconnecting the power-cable. Disk spins down, enclosure LED (and circuit board) still on.+ +Disk spins down -> LED on enclosure stays on -> Still a little waste of energy! Bothers me.
+Computer goes to sleep -> Disk spins down -> Correct!+ +Computer unmounts disk -> Disk spins down -> Correct!+ Ia) Enclosure connected to my *Apple MacBook Pro, 15 inch, Core 2 Duo, Late 2006 (MA609LL)* running Mac OS X 10.5.7 with an DeLock ExpressCard 61386 *via eSATA*. I do this, so that my review can help in the topic of *external disks, sleep mode, PMU, bus powering related to Mac Computers*, and thus your input is very welcome! With the expertise which I hopefully get in this thread, I want to finish my investigation, before posting my final user community review at the product/dealer/price comparison site *First the sleep features of the device did not work as expected!* But through some causally irreproducible actions of me (connecting to different hosts, adding and removing jumper on HD), the energy saving features *eventually miraculously got to work as expected!* ), and which offers an eSATA and USB 2.0 port to the outside. ), which *internally connects a SATA hard disk*, I am using a *Western Digital Caviar Green 1 TB WD10EADS-00L5B1* ( I bought the *external hard disk enclosure LC-Power LC-PRO-35BE3* ( This issue is really tricky as it spans the topic of soft- firm- and hard-ware, and the strange behavior could have resulted from any or through a combination of some of these.
