1.3 Troubleshooting Procedure

 

 

Table 1.3 System level and field troubleshooting

 

 

 

 

 

 

Check to be made

 

Recommended work

 

 

 

 

 

 

 

DC power voltage

 

Confirm that the DC power voltage is within ±5% of the standard value.

 

 

level

 

When measured at +5 V power pins P8 or P9 and GND pins P4-P6, P10,

 

 

 

 

or P12 of the power supply connector, the +5 DVC must be 4.75 to 5.25

 

 

 

 

VDC.

 

 

 

 

Refer to Sections 3.3 and 5.1.4 of the MHV2080BS, MHV2060BS,

 

 

 

 

MHV2040BS Disk Drives Product Manual.

 

 

 

 

 

 

 

DC power ripple

 

Check that the maximum ripple at +5 VDC power is less than 100 mV

 

 

noise

 

peak to peak and 200 mV peak to peak respectively.

 

 

 

 

 

 

 

SATA Interface

 

Confirm that the SATA interface at the drive is properly connected with

 

 

Connection

 

the host receptacle.

 

 

(Including a

 

 

 

 

Connection of

 

 

 

 

Power Segment)

 

 

 

 

 

 

 

 

 

System cable

 

Confirm that all cable connections throughout the system correctly

 

 

 

 

connected.

 

 

 

 

 

 

 

System diagnostic

 

To further isolate the failure, if it can be done, execute the system level

 

 

test

 

diagnostic routine described in the host computer manual.

 

 

 

 

 

 

 

Intermittent or

 

Check the AC voltage level at the power supply section and recheck the

 

 

indefinite error

 

DC voltage level at the disk drive power supply connector.

 

 

 

 

If the AC voltage level is abnormal, or if there is a lot of electrical noise,

 

 

 

 

notify the user.

 

 

 

 

If the DC voltage level is unstable, replace the power supply section.

 

 

 

 

If possible, replace the disk drive. If the fault remains, the disk drive is

 

 

 

 

not the case. For suggestions to isolate the failure further, refer to the

 

 

 

 

hardware and software manuals provided with the system.

The MHV2040BS, with a capacity of 40GB, provides an ideal solution for users requiring dependable storage for basic computing tasks. The MHV2060BS boosts the capacity to 60GB, accommodating users who require additional space for multimedia files and applications. For those needing significant storage, the MHV2080BS comes in at 80GB, catering to heavier workloads and larger datasets.

All three models utilize a robust 5400 RPM spindle speed, offering a balance between performance and energy efficiency. The drives are equipped with an Ultra ATA/100 interface, enabling high data transfer rates for smoother operation and faster file access. This interface is particularly beneficial for users operating in environments with demanding I/O operations.

In terms of technologies, the MHV series integrates advanced features aimed at enhancing data integrity and performance. The drives utilize Fluid Dynamic Bearings (FDB) that minimize mechanical noise and vibration, resulting in quieter operation and increased reliability over time. Additionally, these models are designed to withstand higher shock levels, making them resilient in mobile applications or environments where durability is paramount.

The MHV series is optimized for lower power consumption, ensuring that users can enjoy longer battery life in portable devices while maintaining system performance. With a mean time between failures (MTBF) rating that exceeds 600,000 hours, Fujitsu emphasizes the longevity and reliability of the MHV2040BS, MHV2060BS, and MHV2080BS drives.

Ultimately, the Fujitsu MHV series represents a blend of innovation and practicality. With their robust build quality, commendable performance characteristics, and energy-saving features, they cater to a wide range of storage needs, from everyday computing to more demanding applications, making them a suitable choice for both personal and business environments.
