Thanx for the link, we will check those tools out. <br />
<br />
TrueCrypt is not considered safe anymore??? Will place another question for this because we use TC in everything.<br />
<br />
Back to the question.<br />
<br />
Yes we did force the dismount prior seeing your response, connected again and its seems all ok; nothing lost. &nbsp;Based on you guys experience,<i> why would TC not permit dismount the volume and display the &quot;force&quot; message</i>? &nbsp;(even though we assured nothing was accessing the volume)<br />
<br />
Also,<i> if we have the drive policy to &quot;Quick Removal&quot; active, just disconnecting the USB drive with TC, is it still save</i>? (even though it displays the &quot;force&quot; message))

<div>
Good enough.<br />
<br />
Thanx

We use an external drive with a TrueCrypt volume (used for backups). &nbsp;We have noticed recently that when dismounting it gives us a &quot;Volume contains files or folders being used by applications or system&quot; &quot;Force dismount?&quot;.<br />
<br />
We use Cobian Backup to backup our data to the TC drive. &nbsp;When this message appears, we just exit the apps and sometimes remove it from memory and done it works. &nbsp;But this time, that didn't work.<br />
<br />
We have googled the problems and in some cases it says that it is Windows Indexing that is causing the problem. &nbsp;We disabled it, and still problem.<br />
<br />
Another finding is setting the drive policy to &quot;Quick Removal&quot;, which we already had setup from the start.<br />
<br />
Based on our findings, we are understand that even though the message appear, we can remove without problem.<br />
<br />
Please advice possible cause &amp;&nbsp;proper steps to follow to resolve it.

Safely dismounting TruCrypt volumes and safely removing USB external drive in Windows 10

Encryption is the process of encoding messages or information in such a way that only authorized parties can read it. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.

Encryption

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
