Default External USB-drive and F15

Unfortunately, that doesn't seem to work with one of my firewire
connected drives.

# /sbin/hdparm -B255 /dev/sdd

/dev/sdd:
setting Advanced Power Management level to disabled
HDIO_DRIVE_CMD failed: Invalid argument

I'd already used hdparm, years ago, to save my laptop's internal drive
from an early death.

And, smartctl can't be used with either of the USB or firewire external
drives that I have (to check on them). The interface to the drive is
too dumb, or the program isn't programmed to work through those
interfaces.

Well, the trouble is the drive falling asleep at some time that you
didn't notice... ;-) But since the dozing is some time after the last
access, you'd expect that the file system changes would have been
committed before the drive went to sleep.

I'm beginning to have suspicions that suspending the laptop is part of
the equation.
