Hi guys,

 

need some help, everytime I try to remove a USB hard disk I get a message saying it is not possible because some program is using it.

There is no program (to my knowledge) using the disk, I've tried to wait about half an hour then I got the same message again.

I disabled write-caching for the disk so I can (in theory) unplug the disk without safe-removing it, nonetheless I'd really like to know what is causing the problem and fix it.

The disk is connected to the PC via a USB hub.

I have no issue in removing USB flash drives.

 

Any suggestion?

This is usually due to a process accessing the drive. See this excellent post by jcgriff2 on tracking down the process that may be causing the problem.

Thanks John, always helpful tips.

I already have Process Hacker installed, I think it's a very similar piece of software.

Not sure how to do it exactly but I'll give it a shot.

Thanks again.

If all else fails, you can safely remove it after the computer is shut down.


Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Thanks to you too.

As soon as I have the time I'll try to identify the "guilty process" with Process Hacker.

That's step 1. Step 2 would be fix this problem once and for all.
