I'm looking to replace my TiBook's hard drive due to how loud it gets after just a few minutes of use. I just wanted to confirm that ATA-6 2.5" hard drives would work as replacements? Are there any hard drive manufacturers you recommend or any I should stay away from? I'm looking more for quietness than speed since the most I'll be saving to my laptop are Word documents. I'm mainly looking at this Hitachi model. Does anyone have any experiences with this model or with Hitachi in general? Does anyone have any additional tips for a first timer at installing hard drives? Thanks a lot.
