I don't know how pertinent to this thread this is, but I'm not positive they use the same voltages. I agree that since both 2.5" & 3.5" drives use the same connector then the same voltages should be *supplied* to the drive. However, I don't know how they could pull off the trick of powering a 2.5" drive from a USB connector unless the 2.5" drives required anything other than 5v. I've always assumed that the 2.5" drives simply ignored the 12v power line in the connector (and probably also the 3.3v ... as apparently most (all?) of the 3.5" drives do in order to allow them to be powered via a 5v & 12v 4-pin molex connector plugged into a SATA power connector adapter). I hate it when manufacturers take "shortcuts" and don't fully implement a spec. But it's a fact of life that they do this when "everbody knows" it will work. It wouldn't surprise me at all if the 12v (and 3.3v) pins on most laptop supplies were open. Sorry to view off point so far. -irrational john --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
