So, it's definitely not a hardware problem. This is all on the same machine? If it's been in service since 4.11 days, then it is ancient in computing terms. Don't disregard hardware problems so quickly. It's not just hard drives that can have problems: disk controllers, disk cabling, even failing power supplies can result in these sort of symptoms.
