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. 9 (1 gigabyte shows 1x10 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 t

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 r

4.3.2 Spindle Start Selection When multiple disk drives are connected to the same power supply and turned on simultaneously, a large current will be required at power up. In the above case, it is recommended to turn the motors on one by one at intervals in order to minimize 12V line current. This can be done according to the following 3 jumper pin configurations in the case of NW drive: 1. If Disable Auto Start mode is set (C3:9-10 installed); (1) Use a spindle start command for each drive, issu

5.2 Low voltage differential (LVD) mode The NW and NC drives have two different transceivers to allow customer to use it in traditional systems which may use single-ended drivers and receivers, or to use it in low voltage differential (LVD) systems which use LVD drivers and receivers. Their I/O circuits are selectable using the I/O "DIFFSENS" line. When the I/O "DIFFSENS" line is between -0.35V and +0.5V, the drive interface circuits operate single-ended. When "DIFFSENS" is between +0.7V and +1.
