I am troubleshooting something that has me stumped. Windows Vista Home Premium SP2 64Bit, on a Toshiba A505. The HDD light seems to be flashing more than I think it should be, while the PC is idle. The original symptom was intermittent performance issues. I have used Process Monitor and Activity Indicator to see what is reading/writing to/from the HDD. To be honest, I don't see anything really odd. When the led is flashing, the virtual LED in Activity Indicator is not in synch, which makes me wonder what's going on.
I have scanned for Malware with a litany of tools and found very little and cleaned what they did find. (Malwarebytes, MSE, Super Anti SpyWare, ADWCleaner, TDSS Killer, etc...) I have defragged the HDD and PST files from Outlook.
when loading web pages from MSN, it seems slow in both Chrome and IE. This occurs while the HDD LED is indicating disk activity. Again, ProcMon and AI don't show any significant utilization (disk or CPU) while the LED is blinking. What the heck could be causing the disk to be accessed, but not show in these 2 tools? OR, is there a better tool to use to find out what is chugging away on the disk? I also disabled all of the Toshiba bloat utilities and am running with minimal startup items and services.
Thanks in advance
