  • Verification in linear mode – helps to determine if your drive needs data rescue, has recoverable errors or in its perfect shape.
  • Reading in linear mode – simpler, but faster disk check.
  • Erasing in linear mode.
  • Reading in Butterfly mode (synthetic random read).

S.M.A.R.T.:

  • Reading and analysing SMART parameters from ATA/SATA/USB/FireWire HDD.
  • Reading and analysing Log Pages from SCSI HDD.
  • SMART tests running on ATA/SATA/USB/FireWire HDD.
  • Temperature monitor for ATA/SATA/USB/FireWire/SCSI HDD.

Additional features:

  • Reading and analysing identity information from ATA/SATA/USB/FireWire/SCSI HDD.
  • Changing AAM, APM, PM parameters on ATA/SATA/USB/FireWire HDD.
  • Reporting defect information on SCSI HDD.
  • Spindle start/stop function on ATA/SATA/USB/FireWire/SCSI HDD.
  • Reports can be saved in MHT format.
  • Reports can be printed.
  • Skins support.
  • Command line support.
