laptop hard drive replacement

[ONESHOTKILL]

i have a hp omnibook xe4100 and it currently has a 30gb hard drive.I was thinking about purchesing a 120gb hardrive for it.Would this work on this laptop sumthing like a Fujitsu 120GB MHV2120AH 2.5" 5400RPM 8MB Cache HDD? The laptop is pretty old thats why i am not sure what size hard drive it can handle.
