Showing error and my all family pictures are encrypted in vault

I was given a SanDIsk cruiser drive by a relative, and they told me the files were lost.  When I logged into the SecureAccess Vault, it gave some sort of error message like “Unable to access vault”.  All of his files were encrypted .DAT files that could not be accessed.  The SanDisk Vault application showed an empty vault.

About ready to give up, I started poking around and found this file:

SanDisk Secure Access Vault\System Files\USB Flash Drive-A20046839E03E771.idx

It was ZERO BYTES long, which looked suspicious to me.

I also saw this file:

SanDisk Secure Access Vault\System Files\USB Flash Drive-A20046839E03E771.idx.bak

Which appeared to be a backup of the original Index file.

So I did the following:

  1. Renamed the original “USB Flash Drive-A20046839E03E771.idx” file to “USB Flash Drive-A20046839E03E771.idx.old”
  2. Renamed the “USB Flash Drive-A20046839E03E771.idx.bak” to “USB Flash Drive-A20046839E03E771.idx”
  3. Restarted the Vault application, logged in again
  4. All the files appeared!

Hopefully this can help someone else with a similar problem.
