The usual reasons for DBAN being slow are:
- Bad hardware. DBAN will degrade to PIO mode after a DMA fault and try to finish the wipe. The estimated runtime will get very large very quickly in this case.
- Old drivers. Try the latest posted beta or pre-release if the target computer was manufactured in the last six months.
- DBAN is alway 20% slower than a similar product. You are comparing DBAN against a similar product that cheats on the DoD implementation by "randomly" choosing the null byte on the final character pass.
