When my machine needed a new CMOS battery, I shipped it to their service center and had it back in two days - no charge. When my hard drive appeared to be failing, they sent me a new one via 48-hour UPS, again no charge. These folks are great.
Customer support is outstanding.
He let some locals mess with it. Next day, it wouldn't power up. He called Hitachi, which assured him the five-year warranty would cover the problem. He sent it to Hitachi. We'd like to hear about your experiences with this company.
