Well...the definitive test is to put the drive in another PC. But if you
don't want to get into that before your friend returns, it's understandable.
Until then, you could try simply deleting the drive from Device Manager.
When you reboot the PC (or run "Check for new devices"), if the drive is
recognizable, Windows will re-install it as a new device (you might need to
have a driver disk handy). That *might* fix the problem...but, at the very
least, it won't make the problem any worse. If the PC does not recognize the
"new" device, then it's likely the drive is fried.
A personal opinion on surge protectors. I rarely use them...especially not
the cheap ones. Some protect against just the first major surge or spike and
then function as little more than a power strip after that. They do not
provide the level of protection the makers want you to believe. If I really
want something protected I always use a UPS. I use them on my PCs as well as
TVs and other expensive audio/home entertainment stuff.
Lastly, if the power outage was the cause for the fried drive, Dell does not
owe you a new drive (again, my opinion).
