I am using Garuda GNOME Lite.
Trying to copying folder in USB flash drive. But when copying finished and try to unmount drive. It gives me an error like this...
and after waiting for about 5 to 10 mins... device automatically unmounted.
Device is formatted as NTFS through GParted.
If writing in progress you can't unmount, e.g. it is better to wait for not losing data.
But we do not know how big your folder is?
Maybe baloo or something else is in progress too, too many ???
All in all it is not a problem, it needs only some time 
I also copying files in external hard drive but it dont have problem like this.
Start in terminal top or htop then copy again like before and have a look what's going on
Do you use file browser (which one?), rsync, cp ???
Its inbuilt Nautilus file manager of GNOME. and It only shows file number and speed of copying. I restarted laptop and format pendrive too many times. But ,Yes, before first formating of pendrive I used it as bootable usb drive, is that creates any problem??
?
I do not use NTFS so I cant test.
No.
ok I will try top or htop and copying small file.
Ok ,
some random process is still running after copying finished.This random process running for more time for large file size for 4GB file around 5 to 10 min. and for 142 MB folder it runs for 2 to 3 minutes.
And not much change in resources in top output.
and transfer speed is also very high about 80 mbps.

@tbg I am using default settings and I don't know how use rsync or cp in terminal. Can you plzz provide me steps or any link to do it?
If you want to succeed in using Archlinux getting used to search the wiki is important, lots of information can be found here auch as instructions on how to use rsync
Copying with the "cp" command is super easy, simply:
cp /path/of/file/you/want/copied /pathe/of/destination/you/copy/file/to
No offense intended, but the reason I didn't respond quickly is that this stuff is super easy to find information about. Rsync is more complex, but it gives you a ton of different ways to transmit files from one location to another.
If you intend to stick with Linux, you should definitely learn about this stuff.
Using rsync:
rsync -av /home/study/AllData/Harshad-Mehta-Story/ /run/media/study/3115D7FC626A303D/
sending incremental file list
./

rsync copying finished at 1m and 28s but still I can't unmount the USB drive because some random process is still running and It runs for about 5 mins.
Also I tried,
cp -r /home/study/AllData/Harshad-Mehta-Story /run/media/study/3115D7FC626A303D/
But after copied random process still runs for about 5 mins. And I can't unmount.
This may sound off the wall to you but whenever I find an unexplainable issue I always test another kernel to see if it exists there as well.
Having a fallback kernel is a very good safety precaution anyways so it kills two birds with one stone. I would install the linux-lts kernel and the linux-lts-headers as a test.
You can switch kernels after rebooting at the grub menu screen. You should really always have 2 kernels installed anyways, so it's hardly wasted effort.
