My Windows 7 x64 hard disk light is continuously flashing. I had a look in the task manager but i cant find any programs which is over using the memory or cpu. I was wondering if there are any good free / open source tools to monitor hard disk activity which can tell me which program is causing the IO.
Try disabling your CD/DVD drive in Device Manager. – None – 2012-04-30T17:56:57.230
