- DiskTester: The 'recondition' command for SSDs can now work with as little as 128MB of contiguous space (was 1GB). This helps under conditions where the volume is highly fragmented.
- dgl: new command line tool (command line only at this juncture) with wipe and wipeFree commands. These commands are beta versions at present.
The wipe command supports an easy to use convenience feature: appending the suffix -wipeMe to any file or folder tags it for wiping (“dgl wipe”). All local volumes are scanned for such files in highly efficient fashion, making it convenient to mark many items for wiping, then do it in one invocation. Double confirmation is needed before any files are actually wiped.
The wipeFree command is handy for wiping free space in a variety of circumstances (including interesting cases like free space on disk images, for much improved compression of a dmg file, or helping out SSDs by clearing blocks).
