Zero Stream for Unused Space Erasure Method

[aberhow]

Hi,

I would like to request that a stream of zeros be added to the unused space erasure method. Though this isn't a very secure method, there are instances (disk imaging and virtual machines) where having 0's on the disk in unused parts provide significant benefits for compression.

Thanks,
Andy

You can do this already, by creating a custom erasure method. See page 15 of the User manual (press Help an the Eraser toolbar).

Nugget: HMG IS5 Baseline could be labeled as "0-fill drive"

	sealed class HMGIS5Baseline : PassBasedErasureMethod
	{
		/* other members */

		protected override ErasureMethodPass[] PassesSet
		{
			get
			{
				return new ErasureMethodPass[]
				{
					new ErasureMethodPass(WriteConstant, new byte[] { (byte)0 })
				};
			}
		}
	}
