Maintenance and Diagnosis

Data corruption

When asking for repair, save all data stored in the disk drive beforehand. Fujitsu Limited is not responsible for any loss of data during service and repair.

(5)Notes on handling

a.General notes

a)Vibrations and shocks more severe than allowed will cause fatal damage to the device so be very careful. Be especially careful when unpacking the device.

b)Do not leave the device in a dusty environment.

c)Because the device uses GMR (giant MR head) and static sensitive CMOS semiconductors take the following precautions, be careful of the handling on the following points after the device is unpacked.

Use an antistatic mat, etc. in the environment for handling the equipment. The worker should also be physically grounded (e.g., wearing a wrist strap).

Hold by the DE section, do not directly touch the PCA unit unnecessarily.

b.Unpacking

a)Use a flat workplace, find which side of the pack is up and be careful not to have the wrong side facing upwards. Do not place the device directly on a hard table, place it on something soft such as a rubber mat.

b)Be careful not to apply any excessive force to the packed device when removing the shock absorbing material.

c)When taking the device out of the antistatic bag, be especially careful not to apply any excessive force to the PCA or to the interface connector section.

d)Never ever remove the DE seal label and screws and the DE cover.

c.Installation

a)When the power is ON, do not change the switch setting, or connecting, or disconnecting connectors.

b)Do not move the device or disconnect connectors with the power ON or until the disk drive unit comes to a complete stop after the power is turned OFF. (It is required to wait more than 30 seconds.)

d.Packaging

a)Place the device in an antistatic vinyl bag along with a desiccant (silica gel).

MHV2040AH, MHV2080AH, MHV2060AH, MHV2100AH specifications

The Fujitsu MHV series of hard disk drives, specifically the MHV2060AH, MHV2080AH, MHV2100AH, and MHV2040AH, are renowned for their reliability and performance in the mobile HDD segment. Designed primarily for use in laptops and other portable devices, these drives integrate cutting-edge technologies to meet the demands of today's data-intensive applications.

One of the hallmark features of the MHV series is its high data density, allowing for substantial storage capabilities in compact sizes. The MHV2060AH offers a storage capacity of 60 GB, while the MHV2080AH and MHV2100AH offer 80 GB and 100 GB respectively. The MHV2040AH provides a slightly more modest but still robust 40 GB of storage. This range of capacities ensures that users can select the model that best fits their storage needs.

The drives utilize the latest perpendicular magnetic recording (PMR) technology, which enhances recording efficiency and increases data storage densities. This technology significantly optimizes the use of disk surface area, providing better performance and more reliable data access. Additionally, the MHV series incorporates an advanced actuator system that ensures precision head positioning, enhancing data integrity and reducing error rates during read and write operations.

In terms of performance, the MHV series maintains a revolutions per minute (RPM) rating of 5400, which strikes a balance between speed and energy efficiency, making these drives suitable for low-power applications. The drives are also designed with a low acoustic level, generating minimal noise during operation—a crucial factor for mobile users who prefer quieter devices.

Furthermore, the Fujitsu MHV series features a robust shock resistance design, allowing them to withstand the rigors of mobile computing. This makes them suitable for use in portable environments subject to vibration and physical movement, thus ensuring data security and drive longevity.

Overall, the Fujitsu MHV2060AH, MHV2080AH, MHV2100AH, and MHV2040AH represent a formidable selection of mobile hard disk drives filled with advanced technologies and features, making them well-suited for a wide range of applications in today's fast-paced digital world. With their combination of storage capacity, performance, and durability, these drives continue to serve as reliable solutions for users seeking efficient data storage in portable formats.
