Product Features WD Scorpio MX375M SATA 3 Gb/s SATA 3 Gb/s is the next generation interface for SATA hard drives. It adds to the functionality of the SATA I interface with the following features: Improved Power Management— provides improved power management features including Host Initiated SATA Power Management (HIPM) and Device Initiated SATA Power Management (DIPM).
WD Scorpio MX375M Product Features Reduced Power Spinup (RPS) Applications for 2.5-inch hard drives like the WD Scorpio include USB external hard drives, notebook systems, and Consumer Electronics (CE). Due to the fact that many of these applications are portable in nature, an option for limiting startup current levels and increasing spinup speed is necessary.
Product Features WD Scorpio MX375M S.M.A.R.T. Command Transport (SCT) The SCT Command Transport feature set provides a method for a host to send commands and data to a device and for a device to send data and status to a host using log pages. Standard ATA commands may be interspersed with SCT commands, but SCT commands cannot be nested.
WD Scorpio MX375M Product Features Reliability Features Set 3.6.1 Data Lifeguard™ Representing WD's ongoing commitment to data protection, Data Lifeguard includes features that enhance the drive’s ability to prevent data loss. Data Lifeguard data protection utilities include thermal management, an environmental protection system, and embedded error detection and repair features that automatically detect, isolate, and repair problem areas that may develop over the extended use of the hard drive.

System features include: Filtration System to ensure fast clean-up times Directed airflow to maximize mechanical cooling Increase casting surface area to maximize cooling Ducted air flow to protect read/write elements from heated air Breather filter located at low pressure area Enhanced heat dissipation...
WD Scorpio MX375M Product Features 3.6.9 Automatic Defect Retirement The automatic defect retirement feature automatically maps out defective sectors while reading or writing. If a defective sector appears, the drive finds a spare sector. The following item is specific to automatic defect retirement on writes (write auto-relocation): Data is always written to disk (using automatic defect retirement if required) and no error is reported.
Product Features WD Scorpio MX375M Hot Plug Support SATA supports hot plugging (also known as “hot swapping”), the ability to swap out a failed hard drive without having to power down the system or reboot. This capability contributes to both data availability and serviceability without any associated downtime, making it a critical feature for extending SATA into enterprise applications.

WD Scorpio MX375M Product Features voltage busses. This residual droop needs to be eliminated or at least reduced to a very small value because most power distribution budgets do not provide allowances for this droop. Low ESR bulk capacitors installed on the backplane voltage busses for each hot plug connector can minimize this droop.
Product Features WD Scorpio MX375M could also be a problem with backward compatibility. Both these issues need new specification items in drive specifications to set limits for both the disk drive designers and designers of hot plug enclosures. 3.7.1.6 Hot Plug Removal Issues Generally, removal of hot plug disk drives does not present any technical issues.
WD Scorpio MX375M Product Features Fluid Dynamic Bearings (FDB) Bearing design that incorporates a layer of high-viscosity lubricant instead of ball bearings in the hard drive spindle motor. As an alternative to conventional ball bearing technology, FDB designs provide increased non-operational shock resistance, speed control, and improved acoustics. 3.10 Staggered Spinup and Activity Indication (SATA Power Pin 11) SATA device power connector pin 11 (see “Standard Factory Connectors”...
Product Features WD Scorpio MX375M The write cache adaptively detects random and sequential access patterns during application execution. If a defective sector is found during a write cache operation, that sector is automatically relocated before the write occurs. 3.11.2 Read Cache CacheFlow implements a multiple segment read cache.
WD Scorpio MX375M Product Features 3.14 Security Mode The Security Mode feature set allows the user to create a device lock password that prevents unauthorized hard drive access even if the drive is removed from the computer. 3.14.1 Master and User Passwords The manufacturer/dealer can set a master password using the Security Set Password command, without enabling the device lock function.

AT Command Set WD Scorpio MX375M 4.1.4 SCT Commands SCT commands provide capabilities not covered in ATA/ATAPI-7 for commands that do not fit the ATA command delivery model. Some SCT commands report completion when the command begins execution. Execution progress for these commands may be checked by requesting SCT status. For instance, the host can track the progress of a Write Same command by issueing a status request once per minute.

Glossary WD Scorpio MX375M Perpendicular Magnetic Recording (PMR) - In PMR, the magnetization of each data bit is aligned vertically rather than longitudinally to the spinning disk. The adjacent bits attract instead of repel (as with bar magnets placed side by side), creating more thermally stable bits. PRML (Partial Response Maximum Likelihood) - A read channel using sampled data, active equalization and Veterbi detection to accurately retrieve the user data off the disk.
