The way the question was posed it sounds like that HDD is long gone along with the stash.
Yeah it does sound like that's the case, but you never know, I keep tons of old crap lying around, I'm terrible for it.
The other thing to suggest, forgive me if I'm wrong, but I believe that any backup of that wallet.dat file would work right? even if it was one made before the coins were purchased, so if the OP ever backed it up, before the disk died, maybe to reinstall windows or something, if you could dig out the file it would have the private key and it would find the coins.
