Windows and USB have both experienced power management issues similar to
what you have described ever since Windows 9x. The best way to insure
reliable wake-ups is to directly connect external drives to the
computer, rather than rely on a USB hub. Beyond that, make sure your USB
drivers in Windows, any power management features in the OS, and your
BIOS are as up to date as possible to reduce the likelihood of buggy
code interfering with the sleep or wake-up functions. That includes the
firmware on the external drive(s), as well. Even with all that updated,
I still cannot guarantee completely reliable performance. It's just the
nature of the beast at times.

Subject: [PCBUILD] External HD not recognized on Boot or Wake from
Sleep
From: Joe Trimarchi <[log in to unmask]>

I have a Dell Ispiron 545 running Win 7 Home Premium with 2 external
hard drives connected to a USB 2 hub. Recently the Maxtor external HD is
not recognized either when booting up or waking up after Sleep. If I
unplug the USB cable from the drive and plug it in it is immediately
recognized. I've tried changing the USB cable, using different USB ports
both on the Hub and on the computer but it is still not recognized on
boot or wake up. I would appreciate any suggestions to fix this if
possible. If not I'll replace the drive as the cost of external drives
is quite cheap.

Thanks,

Joe Trimarchi
