Record "deletion" removes the index marker from the device; the record remains to be written over, much like recording over an old audio or video tape. Eventually the record may disappear through fragmentation and overwrites; however, the possibility of forensic reconstruction exists.

Full deletion of obsolete records involves drive formatting and recopying to ensure complete removal, which is generally impractical. A possible solution involves retaining selected high-risk records on a server dedicated to managing volatile records through a combination of file deletion, copying, disk formatting and reloading procedures. If you have a large quantity of e-records, or a device drive to erase or reformat, you should contact IT.
