Note:

  • Low-level formatting a hard drive will destroy all data on the drive and destroy any chance of data recovery. We suggest you make a reliable back up of all data before attempting this.
  • Canceling a low-level format of a SCSI hard drive before it has completed can render the drive permanently inoperable.
  • Low-level formatting can take several hours depending on the drive.
