Here are all the models currently in the database for this manufacturer and drive width. Entries are sorted into sections based on platter density, and then manufacturer drive family.

Some tips:

Drives using odd sizes are sorted into whatever size category that's closest. For example, drives using 150GB platters are sorted into the 160GB/platter section, and drives using 200GB platters are sorted into the 250GB/platter section.
The total capacity of the drive is shown beside each drive model.
A platter-head ratio is shown next to the total capacity tag in brackets. For example, a drive with a (1/2) ratio has one disk and two read/write heads. Drives that leave some amount of their platters unused in order to fit into a certain capacity (such as a 320GB drive based on a 500GB platter and two heads, which would have ~180GB space unusable) are marked as [short-stroked] next to the platter-head ratio accordingly.
Any special features (increased rotational speed, interface types, unusual platter designs and stuff like that) are noted where necessary.

Note: these are Hitachi's last in-house notebook drives. After acquiring IBM's drive business, these were re-branded as the Travelstar 4K80 series, and subsequent Hitachi-branded drives (starting with the Travelstar 80GN and 5K80) were designed by IBM's Travelstar team.
