I have a friend's Dell Vostro 1500 laptop. It is running Windows 7 Enterprise. Core 2 Duo 1.4 GHz, 2 GB 667 MHz RAM, etc.
He has had some problems with it and I've cleaned it up with this forum's help in the "Am I infected - What do I do?" section of the security forum here. At one point during the process I also ran the Hitachi Drive Fitness Test (advanced) and it gave me the code 0x70. Now that we're all done the same test gives the code 0x00 which, I think, means it is normal. Am I correct?
