Assuming you're using windows (you mentionned DLL :))...<br />
<br />
I usually use Filemon (<a href="http://www.sysinternals.com/Utilities/Filemon.html" rel="ugc">http://www.sysinternals.com/Utilities/Filemon.html</a>) to find such information. If the disk is accessed, you will see it.<br />

You may also find other tools at <a href="http://www.sysinternals.com" rel="ugc">http://www.sysinternals.com</a>. This site has a huge bunch of great tools.<br />

Also, Process Explorer is pretty good. At the same link as above.

Is there a program available or method for determining what apps, processes, services or whatever might be causing a &quot;drive still in use&quot; error message when I try to dismount the drive? &nbsp;I figure that since there are programs that show dependencies for DLLs and processes there must be something that shows apps and processes are using a PC's drives at any given time.

Is there a program available or method for determining what apps, processes, services or whatever might be causing a "drive still in use" error message when I try to dismount the drive?  I figure that since there are programs that show dependencies for DLLs and processes there must be something that shows apps and processes are using a PC's drives at any given time.

Is it possible to find out what apps or processes are using a drive?

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.
