  • Firmware downloadable via SCSI interface
  • Selectable even byte sector sizes from 180 to 4,096 bytes/sector
  • Programmable sector reallocation scheme
  • Flawed sector reallocation at format time
  • Programmable auto write and read reallocation
  • Reallocation of defects on command (post format)
  • Enhanced ECC correction capability up to 185 bits
  • Sealed head and disc assembly
  • No preventative maintenance or adjustment required
  • Dedicated head landing zone
  • Embedded servo design
