Note 9. Recoverable error is measured at the nominal condition with voltage, temperature and default error recovery parameters.

Note 10. The drive should be mounted properly (see section 8).

Note 11. MTBF represents a prediction of performance based upon a large statistical sample calculated in accordance with Hitachi's standard procedures.

Hitachi does not warrant that the predicted MTBF is representative of any particular unit or group of units comprising a customer base. The actual failure rates will vary from unit to unit. Surface temperature of HDA is 50°C or less.

A failure defined by MTBF calculation is any event that requires repair or replacement of HDD.

Note 12. Total idle mode power (W) / Total formatted capacity (GB) Note 13. When the Ultrastar 15K73-73 is formatted to 512 Bytes/sector,

the maximum Logical Block Address is (89B88FF)h.

When the Ultrastar 15K73-36 is formatted to 512 Bytes/sector, the maximum Logical Block Address is (44DC47F)h.

Note 14. Power measurement values in operating (Random Seek/ Read/ Write) case are
