I understand that it may not be possible to securely delete a file from the ext3 filesystem, because the filesystem is journalled. I have read somewhere that it may depend on the options used when the filesystem is mounted , i.e those in fstab. I have looked at this file and Linux Mint does not appear to be using the "journalled" option. Is there a Mint technical expert that could definitely confirm what the situation is here?
What I want to be able to do is to ensure that if I delete a file, say using the "wipe -fri" command which overwrites the file 35 times, that this file can NEVER be recovered. If there is jornalling - can this switched off or reset if it would allow the file to be recovered?
