Software License Management

OWC SoftRAID, MacDrive and Disk Aware software requires activation. OWC software is licensed per computer and needs to be activated to use all features.

To activate OWC software you will need a valid serial number. You can access the activation options in the software – both online and offline.

If you have made changes to your computer or need to move your software license to another computer, you can deactivate your license from within the software or through our online system.

Deactivate your license?

OWC software uses activation technology to help users manage installs. You can activate and deactivate anytime through the software. You can also deactivate online. Click the button below to launch the deactivation wizard.

Frequently asked upgrade questions

MacDrive can be used for a five day trial period without activating. After that time, the software must be activated in order to continue using the features of MacDrive.

Activating requires a valid MacDrive serial number. If you have not yet purchased MacDrive, please visit our online store to purchase. You can also purchase an upgrade from a prior version of MacDrive.

MacDrive will prompt you to activate, but you can also open the Activation Wizard anytime by going to Start > All Programs > MacDrive > Activate MacDrive.

– If you have access to the Internet, simply enter your serial number and select “Activate now through the Internet”.

– If you do not have access to the Internet on this computer, but have access on another computer, you can choose “Show other activation options” and select “Activate on the MacDrive website”. You can use the serial number, along with the computer ID displayed on this screen, to activate on our web site.

There are two activation forms depending on which product and version of MacDrive you have:

Current Offline Activation (MacDrive 9 and 10 Standard and Pro and Disk Aware)

Legacy Offline Activation (MacDrive 8)

The activation wizard will always give you the correct link for your version. We recommend using the URL from the activation wizard for that reason. Using the webform, you will receive an activation code that you can use to activate MacDrive.

– If you do not have access to the Internet at all, you can choose “Show other activation options” and select “Activate by phone” and call us using the dialing instructions provided. We are happy to assist you with activation. You may also submit a support ticket and we will send you an activation code via email. Please be sure to include your serial number and computer ID.

– If you continue to have trouble activating, or your serial number is not accepted, please continue to our Knowledgebase article regarding OWC software activation problems.

Prior versions

The same steps will work to activate MacDrive 7 and 8. Please note that you will need a serial number for that version; for example, a MacDrive 10 Standard serial number can be only used to activate MacDrive 10 Standard, and will not work to activate other versions, such as MacDrive 9 Pro, MacDrive 8, or MacDrive 7.

Please note that MacDrive 6 (and earlier) and MacDrive 6 CrossStripe Edition (and earlier), cannot be activated from trial versions. You will need the original full installer for these programs.

In some cases, you may wish to deactivate your MacDrive installation — to unlicense MacDrive and make the license available to be used again. This is particularly useful if you wish to migrate your MacDrive installation to a different computer, or if you’re planning to make major changes (such as hardware changes) that may affect your license. There are two methods that you can use to deactivate MacDrive.

Deactivating without uninstalling: In MacDrive, you can also deactivate without uninstalling by going to Start > All Programs > MacDrive > Deactivate MacDrive. This requires an Internet connection. MacDrive Quick Start also enables you to select Deactivate MacDrive.

During uninstall: MacDrive, if activated through the Internet, automatically deactivates during normal uninstallation in the Control Panel. No special steps are required. If no Internet connection is available, the installation will proceed without deactivating MacDrive.

Regardless of which method you use, please be sure to take note of your serial number before uninstalling if you do not have it recorded in another location. Serial numbers can be accessed through Start > All Programs > MacDrive > Help and Support > MacDrive Support Information. If you purchased MacDrive as a download from, your serial number will also be on your Order Confirmation email.

If you have trouble activating MacDrive again, please continue to our Knowledgebase article regarding Mediafour software activation problems.

You are having a problem with the Software Activation process.

There are four likely causes:

1) You aren’t connected to the Internet while activating, or

2) You are connected to the Internet through a proxy, which is common on business networks, or

3) You have already installed the software on the allowed number of computers (typically just one), or

4) You have replaced enough hardware in your computer that it appears to the activation system that you are now installing the software on a second computer, even though you are not.


1) Confirm that you have an active Internet connection before attempting to activate the software.

2) Confirm that the activation wizard knows your Internet proxy information, which you can likely get from your system administrator if you are on a business network.

3) You may deactivate in the software on on this page.

5) Purchase additional software for the other computers from

6) Contact Support, explain what has changed in your computer, and provide your product serial number. Our support team will contact you and work with you to get the software activated.

The activation code is a time sensitive, one use code that is generated as a part of offline activation. If you are being asked for an activation code, follow the on-screen instructions carefully and you will be able to generate one, using either a webform on any web-capable device or by phone. Either method requires a computer ID which is also displayed in the window.

You can install on one computer at a time per license purchased. If you need additional licenses, please contact us for discounted additional seats.
