If a drive has a damaged head, WD Marvel can be used to disable that head, allowing for partial recovery of data from the remaining functional heads.
A critical requirement for using WD Marvel is the method of connecting the target hard drive to the computer. The tool works only with drives connected directly to the motherboard via a native SATA port or indirectly through a PCI or PCIe adapter card. However, some users have reported success using eSATA ExpressCard adapters with laptops. USB connections are generally supported for full functionality, as the tool needs direct access to the drive's ATA command set.
If you plan to use this utility, always practice on functional, non-critical "donor" drives first to master the vendor-specific command structures before attempting to save critical client data.
