Defraggler freezes when selecting a drive from the list while running a defrag


Recommended Posts

Hello,

As already outlined in the title, Defraggler permanently freezes when I select a drive from the list while defragging a different drive.
I did this while trying to defrag two drives at the same time (I'm not sure this is possible - I was just experimenting).

 

I can consistently reproduce the bug with the following steps:

  • Open Defraggler
  • Click on D: drive
  • Click on "Defrag"
  • Click on V: drive

After doing this Defraggler freezes and never comes back. Task Manager still shows 100% D: drive utilization, so I'm guessing the defragmentation still continues in the background even when the GUI is frozen.

when I open DF, click on D:\ drive, click Defrag, it starts doing its thing.

the Defrag button is then greyed out and cannot be clicked.

 

so for you, you can still select other drives and the Defrag button is available?

I confirm that after clicking Defrag on the D: disk the button is grayed out.

 

I cannot see whether the Defrag button button is grayed out or not for the other drives, as when I select any other drive from the list the program freezes before the GUI is redrawn.

I can't repeat the issue you describe.

After I start defragging one drive, the GUI allows me to pick any other of my drives, albeit, I can't actually start another defrag process on any of them as the Defrag button is not available.

But I can go back to the initial drive selected, check its progress, and continue clicking other options in DF happily.

Got the same Issue.

Windows 10 & latest Defraggler.

I started defragging my HDD, then clicked on another drive and it froze.

Now I cant see the progress it makes or cancel it. Very annoying.

Seems like this wasnt a problem in earlier versions.... might switch back then

Seems like delivering Crappy / worse updates is becoming a trend recently

Just created this account so I can let you know this is still an Error.

and now i'm not sure what to do?

i do not want to end the program and harm my HDD!

Task Manager still shows 100% active on my HDD

If your HDD uses the NTFS file system "in theory end-tasking Defraggler using Task Manager shouldn't harm your data" since in the background it's using the Microsoft Defrag API.

thanks for replying so fast i appreciate it.

 i think the defraggler did his job after one day of running (the HDD is 1 TB)  i did not shutdown anything just kept watching the task manager and now i see that there is no activity on my HDD so i think it's safe to end the task from task manager (the Defraggler is still not responding) 

maybe i'll wait more i don't have to do anything right now but i don't think that i will use Defraggler again if it's not fixed.

Windows 10 in particular can be finicky with some old 3rd party defrag tools with large capacity HDDs (1TB or bigger).

my OS is (Windows 8.1 pro) and i have HDDs with capacity more than 1 TB like one is 8 TB and there is more but i only try one HDD.

but i have defrag most of my HDDs before from windows and i can do more than one at the same time but it take a lot of time at the 1st time i did them and i will go back to windows for now.
