Yes.
H120: uses a single platter 1.8" 20 gigabyte hard drive manufactured by Toshiba. The model name on these drives may read MK2004GAL or MK2006GAL (the 4 and 6 designate model years, and there is no known difference other than the number). Toshiba currently manufactures two other single-platter drives with the same dimensions, the 30 gigabyte MK3006GAL drive and the 40 gigabyte MK4007GAL drive which uses new PMR technology (note: it has not been officially released yet). 120s can both be fitted with these drives without modification.
H140: uses Toshiba's 1.8" double platter 40 gigabyte MK4004GAH/MK4006GAH hard drive (once again, the 4 and 6 only designate model years). It can be replaced by the double platter MK6006GAH or Toshiba's new dual platter 1.8" 80GB drive, the MK8007GAH, which also uses PMR technology. The 140 can only be upgraded to these drives without modification. You can also, of course, replace an MK4004GAH/MK4006GAH with another MK4004GAH/MK4006GAH.
