Wistron 10316-1. По словам клиента за короткое время умирает третий винт (разных фирм). Хаб - bd82hm67 (slj4n). В биосе винт вижу, до "Виктории" он уже в отвале. С рабочим - все в порядке. Не было ли проблем с этой серией хабов?

Подобных проблем я не замечал с этими мостами.
Однако вот что пишет сам производитель:

SATA Signal Voltage Level Violation
Problem: SATA transmit buffers have been designed to maximize performance and robustness
over a variety of routing scenarios. As a result, the SATA transmit signaling voltage
levels may exceed the maximum motherboard TX connector and device RX connector
voltage specifications as defined in section 7.2.1 of the Serial ATA specification, rev 3.0.
This issue applies to Gen 1 (1.5 Gb/s) and Gen 2 (3.0 Gb/s).
Implication: None known.
Workaround: None.
Status: No Plan to Fix.

SATA Differential Return Loss Violations
Problem: The Intel 6 Series Chipset and Intel C200 Series Chipset SATA buffer capacitance may
be higher than expected.
Implication: There are no known functional failures. This may cause a violation of the SATA-IO*
compliance test for Receiver or Transmitter Differential Return Loss.
Workaround: None.
Note: Intel has obtained a waiver for the SATA-IO building block status.
Status: No Plan to Fix.

SATA Ports 2-5 Issue
Problem: Due to a circuit design issue on Intel 6 Series Chipset and Intel C200 Series Chipset,
electrical lifetime wear out may affect clock distribution for SATA ports 2-5. This may
manifest itself as a functional issue on SATA ports 2-5 over time.
• The electrical lifetime wear out may result in device oxide degradation which over
time can cause drain to gate leakage current.
• This issue has time, temperature and voltage sensitivities.
Implication: The increased leakage current may result in an unstable clock and potentially functional
issues on SATA ports 2-5 in the form of receive errors, transmit errors, and
unrecognized drives.
• Data saved or stored prior to functional issues on a SATA device will be retrievable
if connected to a working SATA port.
• SATA ports 0-1 are not affected by this design issue as they have separate clock
generation circuitry.
Workaround: Intel has worked with board and system manufacturers to identify and implement
solutions for affected systems.
• Use only SATA ports 0-1.
• Use an add-in PCIe SATA bridge solution.
Status: Fixed. For steppings affected, see the Summary Table of Changes.
• This issue has been resolved with a silicon stepping for all Intel 6 Series Chipset
and Intel C200 Series Chipset incorporating a minor metal layer change.
• The fix does not impact the designed functionality and electrical specifications of
the Intel 6 Series Chipset and Intel C200 Series Chipset.

SATA Hot Plug Operation
Section 5.16.5 Hot Plug Operation is modified as shown below. Section 5.16.5.1 is
removed.
The PCH supports Hot Plug Surprise removal and Insertion Notification. An internal
SATA port with a Mechanical Presence Switch can support PARTIAL and SLUMBER with
Hot Plug Enabled. Software can take advantage of power savings in the low power
states while enabling hot plug operation. Refer to chapter 7 of the AHCI specification
for details.

Клиенту было предложено заменить хаб (если он только ноутом гвозди не забивает), пока решает...

Думаю Интел не при чем, сейчас такие новые винты пошли 12 года выпуска, уже не первый случай выхода из строя нового винта за 1-2 мес. а Хитачи и Тошиба вообше жуть!
