Note 1. Storage capacity does not include spare sector and spare cylinder.

Note 2. This is the value in the case that the drive is formatted to 512 Bytes/sector. (1 gigabyte shows 1x109 bytes on this document.)

Note 3. Ultrastar 15K73 is formatted to 512 Bytes/sector as the default.

If non-512 Bytes/sector is required, customer can change it by re-format of the drive.

Note 4. Data transfer rate is degraded with cable or host condition or electrical noise. Note 5. These specifications are typical under the following conditions:

1.Voltage is 5.0V/12.0V as measured on the edge of drive connector.

2.Surface temperature of HDA is 40°C.

If SCSI commands are issued during start-up (like TEST UNIT READY or REQUEST SENSE) in less than 10 ms intervals, then the start-up time may be extended.

Note 6. The disk drive orientation for vibration test is shown below.
