Hi, well, this is not a definitive patch but it works. The aim is to be able to wipe the disk without allocating entire space. When you wipe a disk the program fill disk with zero bytes so disk image increase to allocate all space. This just patch detect null byte writes and do not write all zero byte clusters.
This _looks_ like it would severely impact cpu load during a write. Have you done any testing to determine if this is likely to impact a normal usage scenario?
