1.3 GHz AMD Duron 256 MB RAM 3 GB hard disk (contains wanted old PC files [Win98 upgrade]) 15.4 GB hard disk (contains XP only) 40.0 GB hard disk (want to format and use for storage) as soon as i installed XP on my 15.4 hard disk, the H.D.D. light turned on, which i thought was natural cuz after all, i was installed a pretty big OS. but once i started using the OS, it stays on. my CPU is not being overloaded either, i checked its usage its functioning normally around 0 - 12% without any applications running at all. Why is my H.D.D. LED on 24/7, only on this hard disk? My other hard disk, the 3GB, it works properly. I called a friend and he said it could be a system cache problem with the hard disk. The only explanation i can find is PERHAPS that when i installed XP i accidently installed in the NTFS File System on a 15.4 GB Hard drive when i should've installed it on FAT32. If this is the problem, can i go back to FAT32? IF not, what are my options? This problem doesnt seem to affect too badly on OS performance, but definately on XP bootup and shutdown, which takes a good whole 2 minutes for each. ------- another problem, although my Speakers are hooked up correctly, i cant find the device under Device Manager, and i havent been able to use sound. How can i fix this problem? I tried the troubleshooter without much luck.
