EASIS Data Eraser
EASIS Data Eraser is made for secure erasing hard drives, partitions and all other storage devices supported by windows. Secure erasing means overwriting all data with specially, well selected fixed or random patterns. EASIS Data Eraser has implemented several algorithm to erase your data in one or more cycles. More erasing cycles should help to overwriting possible edge magnetization. EASIS Data Eraser writes a simple log file with information about the erasure process.

A secure hard drive erasure is highly recommended if you want to sell your hard drive or leave you hard drive to third party.

EASIS Data Eraser don't erase HPA or DCO sections on hard drives. Normally, this sections should be free from private data. Reallocated or remapped sectors cannot be erased. You can check the count of remapped sector with the most S.M.A.R.T. tools, including 'EASIS drive check'.
EASIS Data Eraser has implemented a intelligent bad sector handling.

Hard drive erasing algorithm

  • Overwriting one time with hex '00'. On the fly verification of written sectors.
  • Two times overwriting with random (crypto random) and hex '00'. On the fly verification of written sectors.
  • German BSI (VS-ITR). Seven times overwriting with special patterns. One time verification with sector based re-read.
  • DoD (Department of Defense) directive. Overwriting three times with fixed pattern. Last time with random pattern. At last time the first block is overwritten with hex00 for easier hard drive reinit.
  • Bruce Schneier algorithm. Overwriting all data seven times, 2 times with fixed patterns, 5 times with random patterns. At last time the first block is overwritten with hex00 for easier hard drive reinit. On the fly verification of written sectors.
  • Peter Gutmann algorithm. All data will be overwriting 35 times with several fixed patterns. At last time the first block is overwritten with hex00 for easier hard drive reinit. On the fly verification of written sectors.

Log file content:

  • Path of log file
  • Name,type,size of hard drive
  • The selected erasure algorithm
  • The selected range for deletion
  • Count of verified sectors
  • Count of no written sectors

System requirements:
