Windows 10: 100% Disk usage while copying data

Hello all,

I've a Dell Inspiron 5577 Gaming laptop (7th Gen Core i5-7300HQ/8GB RAM/Seagate st1000lm035-1rk172 1TB HDD)running Windows 10 1803 Build 17134.320. Whenever I copy paste data from one partition or within the partition, disk usage spike to 100% thereby reducing performance of the computer. I've been facing this issue since I got the HDD replaced under warranty as the previous one crashed on me. ​

Dell representative took the control and worked for almost 2 hours but nothing changed. As per him it was a bug in Windows 10 so I installed Windows 8.1 to verify. Even in Windows 8.1 Ver 6.3 Build 6300, I've the same issue. Normally the disk usage doesn't cause any issue but the moment I need to copy paste data it takes it to 100%. ​

As per the technical specs of my HDD the Data Transfer Rate is (up to) 140 MB/s however I ran Crystaldiskmark to verify and here's the screenshot of it.​

​

Would like to know whether this is a bug (which I doubt) or an issue with the Hard disk drive? Dell representative says that its normal however it isn't.

How should I proceed?


Thanks in advance

:)

 

100% Disk usage while copying data from USB drive


Oddly Winrar wouldn't open it, but 7-zip would....

A very quick look suggests - perhaps surprisingly- itunes.exe is using a LOT of disk I/O, as is Defender




However WPR also reported this on opening the trace:




You might check to see if not allowing Defender to scan USB devices helps.

Don't know why itunes is involved here- any ideas?

It means due to slow write speed my disk usage is high, right?
