Error message when try to defragmenting 1tb drive using My Defrag

Asked By 0 points N/A Posted on -


I get an error message when I try to defragmenting a 1tb drive using My Defrag. At the end of the stage JK Defrag crashes and shuts down with the following error message. Have any idea to resolve this error? Any assistance would be really appreciated. Thanks in advance.

MyDefrag.exe – Fatal Application Exit

Error message when try to defragmenting 1tb drive using My Defrag

Hi there David J Nelson,
This error usually occurs when you are using the SlowOptimize Script. To avoid the problem you can either upgrade your hardware adding it some extra memory, or tweaking the Mydefrag a bit.
Before running the script try to kill all the processes that could slow your computer down, such as updates, messengers, image viewers and the rest of hanging processes you don't need at that moment. You can easily do that via your task Manager in the Processes tab.
If that doesn't help, try changing the settings of the MyDefrag. Set the LowMemoryUsage to yes and try again.
In case the program still crashes, your computer just can't handle the requests and you'll have to use the FastOptimize script instead of the slow one.
Best regards,
Drake Vivian

If you have a 1 TB hard drive and it has only one partition, tools like this will surely have a problem accessing the entire storage. If you have a drive this big, you should create several smaller partitions in it. Anyway, since the program triggered a “memory full” error, try assuming that the memory is really full and can no longer hold additional process.

Close My Defrag then open your web browser and download the free version of CCleaner and install it. Once installed, start CCleaner then go to “Tools” on the left pane and select “Startup” on the right.

CCleaner startup

Scroll down and select a program that you don’t need or is not important then click “Disable.” Disable all the programs that are not important then close CCleaner.

After this, try defragging your 1 TB drive again and see if it works. If this doesn’t work, use the built-in defrag tool of Microsoft Windows to defrag your drive. Just enable back all the programs you disabled with CCleaner. If you want to convert CCleaner to Pro, download the codes and follow the instructions.
