I don't think it's actually spinning up but the electronics are good enough for 
the bios to think there's a drive installed.  I'll give it a try though nothing 
to lose really.

I'm a bit curious about what led the drive not to spin up. FYI, there is a 
feature called "Power-up in standby" that prevents the disk to spin up on boot. 
Perhaps, an upgrade or program misuses led to trigger the wrong command 
unfortunately. If the hdd is stuck in stand-by, then this could mean that 
neither the laptop motherboard nor the OS trigger the "wakeup" command on boot. 
AFAIK, only recent hardware and OS support this feature while most hdd have 
supported it for a longer time (mostly a server feature).

You could try to reconfigure the disk not to use the "Power-up in standby" 
feature. Note that, it is hard to find USB controllers that forward low level 
hard disk drive command. Typically, S.M.A.R.T. and "Power-up in standby" 
features are rarely available with 30 bucks usb to hdd controllers. Better try 
using a zalman zm ve200/ve300 enclosure or perhaps usb 3 enclosures for that 
(but with a few more bucks), or even better plug your hdd to a free ide/sata 
port (the best solution to me).
