  • Programmable drive capacity
  • 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 240 bits
  • Sealed head and disc assembly
  • No preventative maintenance or adjustment required
  • Dedicated laser textured head landing zone
  • Embedded servo data rather than a separate servo data surface
  • Self diagnostics performed when power is applied to the drive
  • 1:1 Interleave
  • Zoned bit recording (ZBR)
