the hard drive is a Toshiba HDD 2181... i pulled it out, and turned the computer on... guess what... no grinding fan like noise, and it went to the "no bootable devices" screen rather quickly... put it back in, and its grinding away, taking forever to boot up again... you can also feel vibration directy over the top of where the drive sits in the computer... and its back to its slow ways of getting to the blue error screen...

i will try your link, but with the drive making this much noise, its almost a dead giveaway...
