Overview: When External Drives Fail, Deadlines Are at Risk
For motion designers and creatives, losing access to project files can halt progress instantly. One San Francisco-based motion designer experienced this firsthand when her 4TB G-Drive Mobile suddenly failed to mount, putting six months of unrecoverable work in jeopardy a case that called for professional external hard drive recovery.
This recovery case outlines how PITS Data Recovery rescued her irreplaceable files and ensured her project timelines stayed intact.

Case Background: 4TB G-Drive Mobile Failure in the Middle of a Project
The designer’s workflow relied on regularly transferring files from her MacBook Pro to the G-Drive Mobile, and then using those files for post-production and final rendering. But during a routine session, her MacBook failed to recognize the drive, prompting the need for MacBook data recovery.
- Device: G-Drive Mobile USB-C, 4TB
- Location: San Francisco, California
- Issue: Drive not mounting, inaccessible on all devices
- Data at Risk: Six months of motion design projects
With no backup available, the designer turned to online research and found PITS Data Recovery.
