I have performed the erase using the DoD and Guttman 35 methods. To check the effectiveness of the erasure I loaded DiskInternals Uneraser to see if the data could be brought up again. The data seems to be scrambled or deleted as it's supposed to be but the file names remain. Is it not possible to delete ALL data including the file names? Sometimes the file names themselves could include information that needs to be deleted.
After discovering this I now change the file name to random wording before erasure to help with the masking. Thanks for the help.
