This are successful suspend-suspend and suspend-resume sessions on my laptop.
It should help you understand what and how it happens.
Restore your pm-utils system to its previous (original state) as asked in
my previous post, which you should look at and understand.
Then you should run both, suspend-suspend and suspend-resume, on your machine
(even if unsuccessful in its objectives) and capture and save it for later
analysis (the logs are overwritten).
By comparing mine and yours you may find the breaking points in execution).
You should concentrate on the first part (suspend-suspend) first - this is
where your external usb harddisk is recognized and handled.
During suspend-suspend, the PM info (APM level) of the harddisk device is
retrieved via hdparm utility, then saved in script '99hd-apm-restore.hook
suspend' (see the script).
First, look at your harddisk and see if APM is supported at all.
# hdparm -I /dev/sda
Your external usb harddisk is /dev/sdb (see your dmesg).
# hdparm -I "/dev/sda" |grep "Advanced Power"
* Advanced Power Management feature set
# hdparm -I /dev/sda |grep "Advanced power"
Advanced power management level: 254
Look at script 99hd-apm-restore.hook to see how this info is checked for.
This PM info (or rather saved APM state) is restored when script
'99hd-apm-restore.hook resume' is executed later on during suspend-resume.
This is visible in the log.
$ cat /var/log/pm-suspend.log
