magnum70 said:to comment on this. I put a 120hd in my 3y.o. comp. I was able to transfer eveything over and it works fine. The only prob is that my comp or mobo only reads 111 gb instead of 120gb. I have the original in there too that is 20gb. I think there something about the mobo and how much hd gb is can reconize. I would like to get my other 9 gb if someone could tell me it's possible and how to do it.
That is the correct size. You see harddrive makers use the decimal form of measuring bits and bytes. We see the drives measured in the binary form of measurment. When you measure in decimal, a gigabyte is 1,000,000,000bytes. So to the harddrive makers a 120GB harddrive can hold 120 1,000,000,000 pieces of information.
Your OS uses binary measurment where one gigabyte is 1,073,741,824. This is why your harddrive shows up as 111GB.
Decimal: 1,000,000,000X120=120GB
1,000,000,000X111=111GB
Binary: 1,073,741,824X120=128GB(approx)
1,073,741,824X111=119GB(approx)
