[Fast in the beginning, then slowing down ?]

I tried running it in safe mode, but it still takes 8-9 h/%.

[Fast in the beginning, then slowing down ?]

Hi,

I have a 4TB disk I have used for about a year (never been defragged). When I ran Windows own defrag it said that only 3% where fragmented. but defragmenting didn't run (stuck at 0%).

Then I tried the Defraggler. And it said that 87% of the files where fragmented.

 

So I started the defrag (with Defraggler) and the first 8% took about 2 hours for each %. But from 9+% it has taken like 8-9 hours per %. it has been running for 2½day now. and only 12% defragged.

 

The drive has like 1TB pics and 2TB video/music files.

My system is not running anything else (closed all non-essential programs)

The drive is my D:/ non OS drive only data storrage

 

 

My question is, is it normal that its farster in the beginning, and then slows down ?
