I think it's
H(itachi)T(ravelstar)<?><speed[2]><??><size[2]><?><height[1]><interface[2]>=
<??>

- First two are for sure.
- Following is a mystical single letter.
- Speed is the first two digits of speed, i.e. 54 for 5400 RPM.
- The next two are strange, they match the marketing/branding name for
the drives, like 7K60 would be HTS7260... . So they might just separate
drive generations or something like that. But they also match the size
of the biggest available drive in that series.
- Size is two digits giving the gigs. 100gig drives have a 10 here.
- Following is a letter that is probably placed as a riddle for anyone
who wants to interpret the naming scheme.
- Height is in full millimeters, 1 digit, i.e. 9 for 9.5mm .
- Interface is a two digit code like this:
   AT =3D IDE/ATA
   SA =3D IDE/SATA
   CE =3D IDE/ZIF
   CF =3D Compact Flash
   L3 =3D SCSI/Ultra320
   LF =3D FC-AL
- Two numerical digits are following, might be some kind of revision,
might be something else.

Andr=E9.
