I just bought a Tyros 2 and don't seem to find many of the drives listed on the Yamaha list from 2005 still for sale. All the drives listed at Newegg.com for example have different model numbers that those on the Yamaha list. Would it be save to buy a currenly available 80 GB 5400 RPM drive such as the HITACHI Travelstar 5K160 HTS541680J9AT00? Thanks?
