Introduction: after my 6-month old WD Elements 1TB HDD died for no apparent reason, I decided to try a different approach, using an USB 3.0 enclosure. But this setup has it's own problems, apparently.
The setup (the relevant stuff):
Lenovo ThinkPad T420 (Lenovo 4180AG8 motherboard, Intel Core i5 2520M CPU, 8 GB RAM, 180 GB Intel 520 series SSD) with Microsoft Windows 7 SP1 64-bit
Sharkoon QuickStore Portable Pro USB 3.0 external storage enclosure with Western Digital Scorpio Blue 2.5 1TB (SATA II, 5400 RPM, 8MB Buffer memory)
The problem:
The drives works normally when the laptop is turned on - the performance is good, no problems so far. But when putting the laptop to sleep (stand-by / suspend), the drive shuts down, makes a single click sound, then spins up again, and repeats this process continuously.
I have to unplug the drive from the USB port to avoid this, but sometimes I'm in a hurry and forget. I'm afraid that this problem might shorten the life of the drive and/or damage the HDD R/W head assembly.
What I suspect:
My suspicion is that the USB 3.0 port is powered during standby. When the system goes into sleep mode, it sends a certain signal to the peripherals to notify the new state, so the the HDD spins down. The enclosure detects that it's powered, and spins-up the HDD again, and so on.
How can I prevent this from happening? Is there a solution to fix this in Windows or BIOS, or do I need to buy a different enclosure?
Thanks!
