Why does partition tool GParted read the 190GB of data twice when shrink a 250GB partition to 190GB?

Why does partition tool GParted read the 190GB of data twice when shrink a 250GB partition to 190GB?

When using GParted to shrink a 250GB partition to 190GB, I thought it will move the 60GB of data back into the 190GB region and call it done.

"Regarding #2 (reading twice):

If I recall correctly, it performs a read test first. I think that's to make sure that there are no “surprises” during the actual move (read and write operations). You don't want to end up with your file system sawn up in two pieces."
