OS Monterey 12.0.1 - SanDisks Have Stopped Working

Contacted sands support. They are working on a fix with apple. No ETA yet. Heard form others that Sandisk could be reformatted on pre-monterey OS to be used as a time machine. Current format attempts fail to unmount the disk. Out of the box the disk can only be used as a storage devise.

The fix does not work for me. I have downloaded the fixes for Mac and Windows I am running Monterey with Parallels for Windows 10.I have tried on both platforms and I get the same error message " This application only runs on a San disk flash drive" The SanDisk is inserted in the usb slotted has been opened. Can anyone tell me what I am doing wrong?

Take a stick that you don't really care if you lose everything. Go to Apple disk Utilities and clear everything! Erase it.

Then go back to SanDisk and install "PRIVATE ACCESS" you will see two files with the same name. Then create a folder on the one that works. One will have a row of folders. Then use the one and place a new folder in it. Call it " My Files"> Or whatever you want. Then drag something in it. Close and then reboot - Then add your password and you should be good to go.

This issue affects 4 tb disks only and only if I try to reformat and or use as a time machine. Disk worked fine as is for plug and file storage out of the box . 1 and 2 tb drives previously formatted disks for time machine work fine after latest os upgrade. (These are older, slower versions). I called sandisk tech support. They informed me that apple is aware and fix is coming with next os update. Work around suggested by them to reformat 4tb on prior version os worked for reformating, but did not work time machine for me. Had to return it.

I had the issue after updating to the new OS, "IMPORTANT: SecureAccess has been replaced with PrivateAccess" this update is from the SanDisk website.

i downloaded the PrivateAccess and installed it on the Extreme disk and it worked for me.

I installed the PrivateAccess on one of my flash drives which previously had the SecureAccess (that no longer works) I was able to create a new vault but no where am I able to access the file in the old vault. So while the new app works, the problem is still we can't retrieve our files. That is what must be fixed!!

FYI; The instructions tell you to download and install it on the HD, this is not correct, it must me installed on the Flash Drive. Download the package, copy it to the Flash Drive then run the install selecting the Flash Drive as the install location.

I did this and all my files were there and the device works as it did prior to the OS Update.

When I did the install and then executed the the PrivateAccess it indicated that there was already a vault and asked me if I wanted to use it, indicated I did, when I entered my original password it took me to all my files.

Can you try the drives on another computer?

I would contact SanDisk, maybe an updated app is required for Monterey.

Thanks! That is a very helpful bit of news! I hope their fix is released soon! That drive is my Time Machine...

I got the same info from Sandisk. I was able to use my old Mac to open the flash drive and copy out all the files. Now the problem is where to put them that is a secure password protected place?

Have the same problem " This Application only runs on a SanDisk Flash drive"
