yea its only during access, it is an older drive its a 40 gig Quantum thats in another comp, its quite loud actually, happens most often when you load a program, ive had this drive in use for a while but i dont recall it being this loud in the past, however it coudl be because i now have it as the windows drive and not just a storage drive so it gets a lot of useage
i have a new 80 gig seagate 7200.7 SATA that you can heear also during read/write but its not as loud,
i never used to hear my HDDs making noise and im guessing they always did but the fans were just too loud and drowned it out, have a much quieter comp now
