Causes of Data Loss in Mobile Device / PDA

Dropped device and no longer turns on
Inaccessible device
Applications that are unable to run or load data
Corrupted data
Media component failure
Media crashes
Fire, water, coffee and other liquid damage
Media surface contamination and damage
Accidental reformatting of device
Accidental deletion of data

Each recovery case begins with a free diagnostic to determine the potential for recovery and to provide a firm price-quote for your review. The initial diagnosis determines whether the media is accessible to our lab equipment. If so, the first priority is to create a raw image of the data on WeRecoverData media so that logical analysis can determine the nature of the data loss situation. If the media is inaccessible our lab will test the components and closely examine its internal health to determine the extent of physical damage.
Recovery of crashed hard disks often involves replacing failed or damaged components in a clean environment (Clean room class 100) and using specialized hardware and software tools to create the raw image. Failed components typically include electronics, read/write heads, head assemblies, magnets & drive motors.
Logical recovery uses the raw image by examining the low-level data sectors and determining what fixes to file system structures are needed to get access to the important data. Sometimes the existing file system structures are missing or damaged so much that data has to be extracted directly from one or more fragments of the raw image.
Once a recovery has been successfully performed, file lists are created and data validity and integrity is checked.
