SanDisk Drive Unlock Damaged

I have a SanDisk Extreme portable SSD that hd the SanDisk Drive Unlock app set up on it to lock it. It was working fine until today. Now that I am trying to unlock the drive to access my files, it gives me an error message when I try to luanch the Unlock app saying ““SanDisk Drive Unlock” is damaged and can’t be opened. You should eject the disk.

I downloaded the SanDisk Secure Access V3 in order to remove the password, but that app is not working either. I installed it on a separate SanDisk SSD drive because it wouldn’t install on the mac computer hard. It installs on the second Sandisk SSD, but when I launch it gives me an error message saying “This application only runs on a SanDisk flash drive”

what is the solution?

I am using an iMac with MacOS Ventura 13.5.1

Hi @Raber,

Have you opened a Support Case? If not opened, for more information, please contact the SD Technical Support team for best assistance and troubleshooting:

Have you found the solution?

I have the same problem on a Mac Mini runing Ventura 13.5.2. The SSD used to start up without a password as I’d told it to trust this computer. Now I just get the unlocker with the same message as the person above: ““SanDisk Drive Unlock” is damaged and can’t be opened. You should eject the disk.” There is nothing wrong with the disk itself as it works fine (including the Unlocker) on a MacBook Air running Ventura 13.6. How to fix this, please?


Here is how I got mine working:

Attach the SSD, then open any folder on the desktop, the on the left pane of the folder, click on the SSD and it will take you directly into the SSD. From there, double click on the unlocker app, it will give you an error message, ignore it and after that you should be able to open it from the main shortcut on the desktop when you attach it next. In my case, after I went into the SSD, I clicked on the unlocker and deleted it. then went out and tried going back in through the main SSD folder on the desktop and the Unlocker worked perfectly as it should.

Hi, This is a late reply as I didn’t use the HD for a while, but the faulty Unlocker problem still exists. I tried your method but when I attach the SSD it does NOT show up on the left side of a folder window; the only thing that shows up on the left is the SSD unlocker, which still doesn’t work. I’m now running Sonoma 14.4.1 but the problem persists. There is nothing wrong with the drive itself as it works fine (with Unlocker) on another machine. I really need to get this fixed - can anyone help, please?

I recommend checking out this link as it could be helpful in resolving your issue. Give it a try and see if it provides a solution to your problem.

Wow - thank you for such a speedy reply, and on a public holiday as well!

That did indeed get me into the SSD.

However, something odd: just to check that all was working fine, I unmounted the SSD and plugged it in again - and got the “Unlocker is damaged” message again. Now I was able to get into the SSD by using SanDisk Security in applications, but this shouldn’t be happening, surely?

But thank you for your help, and at least I have a way into the SSD, even if somewhat roundabout.

Much appreciated.


Sorry - followup to my previous message - the SSD mounts on my desktop but there is nothing showing when I open it.

So something really isn’t working right.

Any ideas?
Thanks again,

It seems like the issue might be related to compatibility or settings on your machine rather than the SSD itself. Have you tried updating your system or checking for any software conflicts? Seeking technical support from a professional might be beneficial in resolving this problem efficiently.

OK, forget the second message I just sent. I unmounted it and mounted it again, and this time the contents were showing. Sorry to email in haste.

Thanks once more for helping me out.


That sounds very good.

Hi - thanks for your reply.

I’m running Sonoma 14.4.1, which is the latest version. The problem with the “damaged” Unlocker didn’t happen right away, it worked for a while, and then just went bad. As I don’t add software other than auto-updates, I’d be surprised if it it were a (new) software conflict, but anything’s possible. However, as it’s possible to get into the SSD at least a roundabout way, I might just leave it at that. (The only Mac expert I know in my city doesn’t do phone consultations, and it would be a schlep without a car to take my Mini across town.)

All best,

@tanya Figured out the solution to "Sandisk Drive Unlock” will damage your computer. You should eject the disk.

  1. You need to right click on it, and click "Get Info
  2. There’s a dropdown menu under General, click "Override Malware Protection
  3. A popup modal / menu will appear, click Allow Anyway

Then you should be in!

Hi David,

Thank you for your reply. Do you mean that an earlier post about Sandisk Drive Unlock will damage my computer? (I mean, I didn’t post a question along those lines.) In any case the solution proposed didn’t apply to anything on my machine so I don’t think any damage has been done. “Office” replied to me right away when I contacted support (on Good Friday no less) and gave me a solution that works, although I have to do it a somewhat roundabout way by going through Sandisk Security in Applications (the popup Unlocker still claims to be damaged).

But good suggestion about Malware protection. I think I know where that originates on my machine.

Best regards,
