Please help me. Periodically my hard disk makes a sound like a rodent is gnawing on it; "grrr-grrr-grrr-grrr" repeated between 2 and 6 times in sequence - most CPU processes stop for a few seconds while this is going on. It seems to occur mostly on boot-up or start-up of an application.
I recently cleaned my hard disk of malware - very many thanks to Kenny94 on your Malware Staff for his invaluable assistance - and have also run a RegEdit program of PC Tools (which I don't believe did anything significant). To the best of my recollection the problem has occurred from around the time recently that Microsoft Support remotely installed a HotFix solution for MS Outlook.
MS Windows XP Pro, version 2002, SP2 on a Intel Pentium 4 CPU 3.20 GHz machine with 1Gb RAM, about 2 years old, with 2 HDD.
Please tell me it's not my HDD going bad ! :-((
