I have a cruzer glide 32GB sandisk encrypted USB. I recently was prompted to upgrade from v2 to v3. Unfortunately, I neglected to back up my files. When installation of v3 was completed, I could not read any of my files. I tried with one of the commercially available recovery softwares, but all I can recover are .htm and .pdf files concerning the modialities of the upgrade. Now I have uninstalled v3, and am back to v2; however, I still cannot know if my files still exist, or have been permanently erased. I am very naive technologically, but I would hope that the files are still there, but unreadable. Is there any way to recover these files?
I apologize if this question has already been asked; I am new to the forum. Thank you for any help that may be offered.
