USB hdd does not stay in suspend but PC does

When I put the machine into suspend, the screen goes black and the CPU fan stops spinning. As well, my external HDD (USB/eSATA) stops spinning and the light turns off but only for about 1-2 sec. After that short time, the drive spins up again but everything else in the machine remains in suspend mode.

I tried using laptop-mode-tools per the suggestion in the thread I linked, and set it up to control hdds on AC power or battery, but the problem continues. Suggestions are welcome.

Note - My problem is similar to the one described in this thread, but unique enough to warrant a new thread.

Have you tried to suspend USB modules? In /etc/pm/config.d/suspend_modules:

SUSPEND_MODULES="ehci_hcd uhci_hcd usbcore"

On my laptop it takes almost five seconds to spin down external HDD after suspend computer.

I added that file and suspended the machine, but no good I also edited my first post with more details. In a nutshell, the hdd does go to sleep for 1-2 sec but then spins back up while the machine is suspended for reasons I cannot understand.

This is a good question. I'm having the same situation with my own USB hard drive, using laptop-mode, pm-suspend and acpid. Just a guess - can udev be used for suspending devices?
