Barracuda 36ES2 Product Manual, Rev. B 5.0 13 Reliability specifications The following reliability specifications assume correct host/drive operational interface, including all interface timings, power supply voltages, environmental requirements and drive mounting constraints (see Section 8.3).
PAGE 24
14 Barracuda 36ES2 Product Manual, Rev. B error (15h) is reported with a Medium error (3h) or Hardware error (4h) reported in the Sense Key. This is an unrecoverable seek error. Unrecoverable seek errors are classified as failures for MTBF calculations. Refer to the SCSI Interface Product Manual, part number 75789509, for Request Sense information. 5.2 Reliability and service You can enhance the reliability of Barracuda 36ES2 disc drives by ensuring that the drive receives adequate cooling. Section 6.

Barracuda 36ES2 Product Manual, Rev. B 5.2.6 15 Hot plugging Barracuda 36ES2 disc drives The ANSI SPI-3 (T10/1302D) document defines the physical requirements for removal and insertion of SCSI devices on the SCSI bus. Four cases are addressed. The cases are differentiated by the state of the SCSI bus when the removal or insertion occurs.
PAGE 26
16 Barracuda 36ES2 Product Manual, Rev. B The process of measuring off-line attributes and saving data can be forced by the RTZ command. Forcing S.M.A.R.T. will reset the timer so that the next scheduled interrupt will be two hours. The drive can be interrogated by the host to determine the time remaining before the next scheduled measurement and data logging process will occur. This is accomplished by a log sense command to log page 0x3E. The purpose is to allow the customer to control when S.M.A.R.T.

Barracuda 36ES2 Product Manual, Rev. B 17 There are two test coverage options implemented in DST: 1. extended test 2. short test The most thorough option is the extended test that performs various tests on the drive and scans every logical block address (LBA) of the drive. The short test is time-restricted and limited in length—it does not scan the entire media surface, but does some fundamental tests and scans portions of the media.
PAGE 28
18 Barracuda 36ES2 Product Manual, Rev. B Short test (Function Code: 001b) The purpose of the short test is to provide a time-limited test that tests as much of the drive as possible within 120 seconds. The short test does not scan the entire media surface, but does some fundamental tests and scans portions of the media. A complete read/verify scan is not performed and only factual failures will report a fault condition. This option provides a quick confidence test of the drive.

Barracuda 36ES2 Product Manual, Rev. B 8.0 Note. 35 Installation These drives are designed to be used only on single-ended (SE) or low voltage differential (LVD) busses. Do not install these drives on a high voltage differential (HVD) bus. The first thing to do when installing a drive is to set the drive SCSI ID and set up certain operating options. This is usually done by installing small shorting jumpers on the pins of connectors J2 and J6 on the PCBA (or J1Auxiliary on the LW model).
