Erasure time
- The erasure time changes significantly, depending on the erasure method, the PC's hardware specification and the hard disk's connection mode. This example should be used only as a guide.
- If the hard disk has a lot of hardware troubles(bad sectors), the expected erasure time might be inaccurately, and the erasure time might be long greatly.
- If two hard disks are connected to each IDE controllers(one is connected to Primary and the other one is connected to Secondary), Disk Shredder 4 erases the two hard disks' data at the same time(theoretical erasure speed is about twice).
