2.2Formatted capacity
* One GB equals one billion bytes when referring to hard drive capacity. Accessible capacity may vary depending on operating environment and formatting.
2.2.1
LBA mode
When addressing these drives in LBA mode, all blocks (sectors) are consecutively numbered from 0 to
n–1,
where
n
is
the number of
guaranteed sectors as defined above
.
See
Section 4.3.1, "Identify Device command"
(words 60-61 and 100-103) for additional information about 48-bit addressing
support of drives with capacities over 137GB.
2.3
Recording and interface technology
2.4
Start/stop times
Power-on to ready time is based on typical operating conditions, default full current spin-up profile, and clean shutdown prior to
measurement. To ensure a clean shutdown a Flush Cache, Standby, or Standby Immediate command must be completed before
removal of interface power.
An unexpected power loss event, spin up at cold or hot temperature extremes may cause the drive to exceed the typical and max
time to ready by 5 to 20 seconds. Extended time to ready is dependent on cache state and environmental conditions prior to the
unexpected power loss and during the subsequent power on.
