It is good, but it has weaknesses. Among other things, it will believe the drive electronics even if the data provided is obviously wrong. For example, if the drive electronics tells DBAN that your 100GB disk is really a 100MB disk DBAN will happily clean the first 100 MB and report success. I do professional drive cleaning (e.g., 100-1000 drive batches) and DBAN is a good tool. But it is far from perfect. So use it carefully. Lee Winter NP Engineering Nashua, New Hampshire
