I recently needed to change the disk in my laptop (Acer running Vista) and used an external bay to connect the old, then the new disk to a server,
I happened to notice, when I removed the new drive, that it seemed to weigh more than when I plugged it in. I carried out some tests, and found that the 'full' drive weighed more with data on it than after carrying out a full disk delete and reformat. After I copied data to the new drive, it weighs more than when it was new.
Does anyone have the algorithm to relate data volumes to increase in weight?
Does compressing the data with ZIP or TAR make it weigh more per megabyte?
Are there limits to this, or will it just keep getting heavier until it's completely full?
What difference does the operating system make ?
