Data Recovery of 378GB After SanDisk External Hard Drive Fails on Mac in New York City

Data recovery became urgent for a customer in New York City when a SanDisk Extreme Pro 2TB external hard drive suddenly stopped working. When the drive was connected to a Mac computer, it did not appear, mount, or respond in any way. Inside the device was 378GB of important personal data, including family photos, creative projects, documents, and files collected over many years. 

The external hard drive had worked normally in the past. One day, it simply stopped being recognized. The customer tried different USB ports, cables, and even multiple Mac computers, but the result was always the same. The hard drive remained invisible. With no access to their files and growing fear of permanent loss, the customer contacted WeRecoverData, a global leader in professional data recovery services. 

When the SanDisk drive arrived at the WeRecoverData lab, engineers began a full diagnostic. Testing showed that the hard drive was receiving power, but the internal firmware had failed. Because of this firmware issue, the Mac operating system could not mount the volume or access the file system. 

Firmware failures like this are common in external hard drives and can cause sudden data loss without warning. While the data is still stored on the drive, special tools and experience are required to access it safely. 

To begin the data recovery process, WeRecoverData engineers bypassed the failed firmware and connected the hard drive to a forensic-grade recovery system. This allowed direct access to the raw data on the disk without causing further damage. 

Once the raw data was secured, the recovery team rebuilt the file system. Files and folders were carefully reconstructed one by one. Documents, photos, videos, and personal files began to reappear as the structure was restored. 

After detailed and careful work, the data recovery was complete. 

All 378GB of data was successfully recovered, fully intact and organized. The recovered files were returned to the customer on a new, reliable external hard drive, ready to be used again. 

The customer was relieved and grateful. What started as a moment of panic in New York City ended as a full data recovery success thanks to WeRecoverData. 

At WeRecoverData, data recovery is about restoring more than files. It’s about bringing back peace of mind. Whether an external drive won’t boot, mount, or respond at all, WeRecoverData is here to recover what matters most.
