And just to muddy the waters somewhat..

I have an extra hard drive caddy for my Dell notebook,
with a different 2.5" drive mounted in it.

When using THAT drive, my machine cannot resume successully
from suspend-to-RAM.  Hangs with the hard drive light on solid
some of the time, and not on other times.
Drove me crazy figuring this out, but I eventually tried a
different drive and it worked fine.

So.. not all drives work for me.

Now, the drive that doesn't work with suspend/resume (RAM)
happens to claim to support Advanced Power Management.
Except that "hdparm -Bxx" has zero effect on it -- cannot enable
it or modify the setting in anyway.

My other drives also have the APM feature, and have it turned *on*,
and "hdparm -Bxx" can be used to turn it on/off and modify the setting.

Very weird, possibly not related to the resume failures.  Or maybe.

Cheers
