I have Ghost 2002, which I periodically use to create a disk (not partition) image that I store on another disk in a removable rack.

Yesterday my main disk -- 40MB -- began to sound like it might die soon, so I decided to get a new 40MB disk to replace it. But when I was checking out the WD400JB 40MB drive, I noticed that they sell the 80MB version of the drive for just $3 more (!), so I figured that even though I'm currently using only 28.7GB of my 40MB, why not get the 80MB disk for future expansion room.

Then it occurred to me that when I restore the Ghost image of my 40MB onto the new 80MB disk, I might wind up with only 40MB (used + available) -- i.e., rather than 80MB.

Is that normally correct? If so, is there some way I could get Ghost to make the full 80MB available, in the same partition?

By the way, I seem to remember reading years ago that the real-world disk access speed of a larger disk will be greater than that of a smaller disk. As long as I still have less than 40 MB of data, is there any disadvantage of using a 80MB disk rather than a 40MB?
