The Toshiba MK1011GAH will have two platters.Does anyone know how many platters this (or the Toshiba 100GB) has?
The 60 GB Seagate drive uses one platter, so it's pretty safe to assume that the 120GB variety, if it eventually appears, will also use two.
For the Toshiba, yes. Most of the specs are nearly identical to the 80GB version (newer ATA spec, though).Is it the same form factor as the current 80GB drive?

The available Seagate specs are still a little sketchy, but it does appear to have different dimensions just based on appearance alone (they look so different with their skins torn off!). It may or may not be a drop-in replacement for the Toshiba ones.
