I have one of these... at least... maybe I do... I sent my PB in for repair because of the trackpad issue and haven't actually noticed the noise since then... maybe they changed HD's out... I'll have to check when I get home!andrewfee said:The older machines had Seagate drives that made a noise every few minutes that I can only describe as a ball bearing dropping on metal.
Personally it didn't bother me; it ran a bit cooler, and was still very quiet. Great machine regardless imo.SilentPanda said:I have one of these... at least... maybe I do...

Very cool... I suspected it was something like this, but I wasn't sure. Thanks for the info.Bern said:I have a BTO PowerBook with a 100GB HDD. The HDD,by Seagate, utilises a technology called "STIR" - Seek To Increase Reliability. a technology built into the drive controller that randomly seeks when the drive is idle in order to keep the drive head from sitting in one place too long (which creates heat that can potentially harm the integrity of the media). This is a patented Seagate technology which helps to protect your HDD from excess heat. This was one of the more notable differences for me between this PowerBook and my previous Rev C model. The amount of heat that rose from the Rev C, for me, was disturbing. However my current PowerBook is considerably cooler by comparison.
The Seagate 5400rpm HDD also uses less power, similar to a 4200rpm drive. On my PowerBook I get about 4.5 hours battery life.
STIR is the sound you are hearing and nothing to worry about. I actually only hear it when I'm on the internet reading through long articles.
Hehehe, that's exactly what I think of when mine does that! It's a huge 100gb in a 12" pb, so I don't mind if it's a bit noisy...but generally, it's pretty quiet.Sutekidane said:[The HD] is...noisy when the heads park, which happens more often than I'd like.
