I have been using the "secure empty trash" option when I have had to delete sensitive files for a while now. I had been feeling pretty good about the fact that those files were gone for good until I checked in Time Machine. To my horror I found that every single document I deleted, whether securely or just the regular way was still to be found on my Time Machine drive. I have tried to go in and delete the files from the TM drive but the disk is locked. I also tried, and failed, to delete the files from within TM. Does anyone know how to delete files off the TM drive without just reformatting the drive and losing all the other backups?
