Hi Cloaked,
I recommend going to the manufacturer's website of the hard-drive and download their "HDD Diagnostics Utility". Put the program onto a CD, boot the computer to it, and then test the HDD for any errors. If that netbook doesn't have an integrated CD/DVD drive, try and see if you can obtain one from friend that has an external CD/DVD drive.
Also, I would recommend backing up the files on the HDD to another working computer so that your data is safe. Hopefully everything works out for you.
