Thought I'd post this since so many folks referenced 'shred'. I have no idea how valid this poster's comments are and would be interested in knowledgeable comments on it: (from http://www.oreillynet.com/pub/wlg/6592?page=last&x-maxdepth=0 ) from man shred 2005-03-04 06:47:03 markybob [Reply | View] : Since shred writes on such a low-level, it doesn't actually : matter what kind of filesystem is on the partition [snip...] CAUTION: Note that shred relies on a very important assumption: that the filesystem overwrites data in place. This is the traditional way to do things, but many modern filesystem designs do not satisfy this assumption. The following are examples of filesystems on which shred is _not_ effective: * log-structured or journaled filesystems, such as those supplied with AIX and Solaris (and JFS, ReiserFS, XFS, Ext3, etc.) * filesystems that write redundant data and carry on even if some writes fail, such as RAID-based filesystems * filesystems that make snapshots, such as Network Appliance's NFS server * filesystems that cache in temporary locations, such as NFS version 3 clients * compressed filesystems _______________________________________________ EUGLUG mailing list [email protected] http://www.euglug.org/mailman/listinfo/euglug
