If you are seeing this dialog it means some programs are locking your device and preventing it from being stopped. But don't worry our program has magic "Forced Stop" feature and other means to unlock and prepare you device for safe removal.
This dialog displays the list of processes preventing the device from safe removal. You can also see what certain files are opened by these processes on the device (press "+" sign before the process):
To remove the device safely you can do the following:
'svchost.exe' and 'system' locking processes. What are they?On the screenshots above you are seeing 'svchost.exe' and 'system' processes among the other ones. If you expand these processes you will see the following list of locked files:
The 'System' process is locking $Extend\$RmMetadata\$TxfLog\* files and 'svchost.exe' is locking 'System Volume Information\tracking.log' and '$Extend\$ObjId' files. These files are just invisible system files that are used by NTFS file system drivers, or in other words by the operating system itself. In case when these processes lock the mentioned files only they do not prevent drives from being safely removed despite the program displays them. Usually you are seeing these processes along with other processes that actually lock the device.
But in some cases the program shows only these two processes locking exactly these filesystem files. That means that there are no programs actually locking processes and the device cannot be stopped for another (unknown for us) reason. So to safely stop this device just use the "Forced Stop" feature in most cases it helps to unlock such unknown lock.
