Is Defraggler napping on the Job?


Recommended Posts

This is downright ridiculous. Over 30 minutes now to defrag 13GB of data (mostly large files) on a 5TB drive that is currently 54GB full.


Drive is USB3, 200MB/s Read, 190MB/s write.


I could have moved all 54GB of data off and back onto it in 20 minutes....


So what exactly is it doing?

45 minutes currently remaining....


I don't remember this app being awful when first released.


Edit: I cancelled it about 20 minutes later and finished the defrag and optimize in under a minute with another defrag tool.

OS and DF versions?


is this the first time you have run DF on the 5TB drive?
how old is the 5TB drive?


I seem to recall reading in a past thread about DF not liking drives over 3TB (but it could just have easily been regarding some other program)

5TB is 2 weeks old nothing wrong with it.


I just downloaded the latest Defraggler from the builds page (no install, zip) 2.18.945 x64, latest as far as I can tell.


I've been using other defrag tools previously in the last week, and decided to try Defraggler again.


The drive is used primarily for raw OBS encodes only ( large 2GB+ video encodes).


Edit: OS is Windows 8.1 64 Pro

so this is the first time you have run DF on this drive?


what is your OS?


I went through the review history of back versions and discovered this;

  • v2.13.670 (18 Feb 2013)

    - Added Quick Defrag scheduling.
    - Added Fragmentation Threshold to scheduled defrag options.
    - Added option to close Defraggler after defragmentation is complete.
    - Added support for 3TB external drives.
    - Added support for drives with allocation units greater than 4KB.
    - Added support for ReFS file systems.
    - Updated translations.
    - GUI and usability improvements.
    - Minor bug fixes.

So if that was to add 3TB support, maybe 5TB isn't handled very well yet.
