Seagate drives also may be used at the maximum available capacity at a given sector size, but the excess capacity above the guaranteed level will vary between 10K and 15K families and from generation to gener- ation, depending on how each sector size actually formats out for zone frequencies and splits over servo bursts.

    The drive keeps track of the logical block addresses of the data stored in each segment of the buffer. If the cache is enabled (see RCD bit in the Fibre Channel Interface Manual), data requested by the host with a read command is retrieved from the buffer, if possible, before any disc access is initiated.

  • Page 30: Unrecoverable Errors

    5.1.2 Unrecoverable errors Unrecoverable Data Errors (Sense Key = 03h) are specified at less than 1 sector in error per 10 ferred. Unrecoverable Data Errors resulting from the same cause are treated are 1 error for that block. 5.1.3 Seek errors A seek error is defined as a failure of the drive to position the heads to the addressed track.

  • Page 31: Hot Plugging The Drive

    5.2.3 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.

  • Page 32: Thermal Monitor

    Performance impact S.M.A.R.T. attribute data is saved to the disc so that the events that caused a predictive failure can be recre- ated. The drive measures and saves parameters once every two hours subject to an idle period on the FC-AL bus.

  • Page 33: Drive Self Test (Dst)

    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. Cheetah 10K.7 36GB FC Product Manual, Rev. A...

    5.2.7 Product warranty Beginning on the date of shipment to the customer and continuing for a period of five years, Seagate warrants that each product (including components and subassemblies) that fails to function properly under normal use due to defect in materials or workmanship or due to nonconformance to the applicable specifications will be repaired or replaced, at Seagate’s option and at no charge to the customer, if returned by customer at cus-...
  • Page 36 Shipping When transporting or shipping a drive, use only a Seagate-approved container. Keep your original box. Seagate approved containers are easily identified by the Seagate Approved Package label. Shipping a drive in a non-approved container voids the drive warranty. Seagate repair centers may refuse receipt of components improperly packaged or obviously damaged in tran- sit.

  • Page 44: Air Cleanliness

    The sil- ver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the most damaging. In addition, electronic components should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or exposed to an ambient relative humidity greater than 95%.

  • Page 45: Acoustics

    There will not be any discrete tones more than 10 dB above the masking noise on typical drives when mea- sured according to Seagate specification 30553-001. There will not be any tones more than 24 dB above the masking noise on any drive.

  • Page 47: Defect And Error Management

    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).
  • Page 48 Table 12 equates the read and write retry count with the maximum possible recovery time for read and write recovery of individual LBAs. The times given do not include time taken to perform reallocations. Reallocations are performed when the ARRE bit (for reads) or AWRE bit (for writes) is one, the RC bit is zero, and the recov- ery time limit for the command has not yet been met.

  • Page 49: Fc-Al System Errors

    FC-AL system errors Information on the reporting of operational errors or faults across the interface is given in the Fibre Channel Interface Manual. The FCP Response returns information to the host about numerous kinds of errors or faults. The Receive Diagnostic Results reports the results of diagnostic operations performed by the drive. Status returned by the drive to the initiator is described in the Fibre Channel Interface Manual.
