/But/ I recall reading somewhere that no file shredder will completely obliterate your files if you are using a journaling FS such as ext3.
Nothing to stop you remounting the filesystem as ext2, then shred your files, do multiple syncs, then remount as ext3.
Modern disk forensics may allow a skilled operator to recover your "deleted" data.
They might be able to recover the data because AFAIR ext3 does not clear the data blocks - it only resets the metadata to a state that shows that/those data block[s] as unused. On disk, the data does exist, until it is eventually overwritten.
