If the number of write data logical blocks exceed the size of the segment being written into, when the end of the segment is reached, the data is written into the beginning of the same cache segment, overwriting the data that was written there at the beginning of the operation;...
Reliability specifications The following reliability specifications assume correct host and drive operational interface, including all inter- face timings, power supply voltages, environmental requirements and drive mounting constraints Seek error rate: Read Error Rates Recovered Data Unrecovered Data Miscorrected Data Interface error rate: MTBF: Service life: Preventive maintenance:...
Special equipment is required to repair the drive HDA. To achieve the above service life, repairs must be per- formed only at a properly equipped and staffed Seagate service and repair facility. Troubleshooting and repair of PCBs in the field is not recommended because of the extensive diagnostic equipment required for effective servicing.
5.2.6 Hot plugging the drive Inserting and removing the drive on the FC-AL will interrupt loop operation. The interruption occurs when the receiver of the next device in the loop must synchronize to a different input signal. FC error detection mecha- nisms, character sync, running disparity, word sync, and CRC are able to detect any error.
If DST encounters an error during either of these tests, it reports a fault condition. If the drive fails the test, remove it from service and return it to Seagate for service. 5.2.8.1 DST Failure Definition The drive will present a “diagnostic failed”...

Power dissipation ST373405FC Typical power dissipation under idle conditions is 11.3 watts (38.6 BTUs per hour). To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure 7). Locate the typical I/O rate for a drive in your system on the horizontal axis and read the corresponding +5 volt current, +12 volt current, and total watts on the vertical axis.
Non-operating –40° to 158°F (–40° to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This specification assumes that the drive is packaged in the shipping container designed by Seagate for use with drive. HDA Temp.
Disc drives shipped as loose load (not palletized) general freight will be packaged to withstand drops from heights as defined in the table below. For additional details refer to Seagate specifications 30190-001 (under 100 lbs/45 kg) or 30191-001 (over 100 lbs/45 Kg).

Defect and error management The drive, as delivered, complies with this product manual. The read error rates and specified storage capaci- ties are not dependent upon use of defect management routines by the host (initiator). Defect and error management in the SCSI protocol involves the drive internal defect/error management and FC-AL system error considerations (errors in communications between the initiator and the drive).
When the RC bit is one, reallocations are disabled even if the ARRE or AWRE bits are one. The drive will still perform data recovery actions within the limits defined by the Read Retry Count, Write Retry Count, and Recovery Time Limit parameters. However, the drive does not report any unrecovered errors. Table 2: Read and write retry count maximum recovery times Maximum recovery time per...
Installation Cheetah 73LP FC disc drive installation is a plug-and-play process. There are no jumpers, switches, or termi- nators on the drive. Simply plug the drive into the host’s 40-pin Fibre Channel backpanel connector (FC- — SCA) no cables are required. See Section 9.5 for additional information about this connector. Use the FC-AL interface to select drive ID and all option configurations for devices on the loop.
