How Corrupted Accounting Data Was Recovered from a WD Hard Drive – Stellar Gurugram

A stainless-steel surface finishing company faced a setback when several important files stored on a WD USB hard drive became inaccessible. Instead of opening normally, the files displayed an error message: “The file is corrupted and cannot be opened”. What looked like a minor technical glitch quickly turned into a serious concern as our client’s business operations were impacted.

Without access to these files, the company faced delays in production planning, difficulties in tracking pending customer orders, and challenges in reconciling vendor payments and inventory records. The disruption started affecting both ongoing domestic, and international projects, making the situation increasingly urgent. At this stage, the company realized that professional corrupted file recovery services were required to prevent permanent data loss.

Multiple in-house attempts to fix the problem failed. The risk of imminent data loss was looming large. The productivity already taking a hit and time running out, the organization needed a dependable recovery solution.

That’s when they turned to Stellar Data Recovery Gurugram service center. Read on to learn how Stellar successfully repaired the damaged files and restored the critical business data, helping the business resume normal operations with minimal disruption.

An Overview of the Case

• Drive Type: USB Hard Drive
• Capacity: 1 TB
• Brand: WD
• Model No.: WDBHHG0010BBK-EB
• Data Impacted: Business Operations and Accounting Records
• Files Impacted: .xlsx, .doc

The Challenge

The USB drive provided to us contained multiple files that were not opening including the Excel and the Word documents. Further examination revealed that the file size displayed as zero bytes, indicating either data corruption or data loss.

Our Approach

Our approach varies depending on the severity and complexity of the problem. In this particular case, we adopted a structured corrupted file recovery methodology aimed at identifying and extracting the required data despite the zero-byte condition. Read on to know about the approach we took in order to recover the data.

Inspection and Evaluation

Our data recovery experts connected the drive to a specialized workstation used for hard drive data recovery and advanced storage diagnostics. The result was positive, as no physical damage was found during the initial inspection. However, the files were not opening and displayed the same error on our system as well.

We then used our proprietary tools to scan the entire drive to identify recoverable data. As a part of the process, we also contacted the client to gather additional details, including:

• What type of data was stored on the drive?
• Possibly name of the files.

Disk Imaging

We created a sector-by-sector disk image of the USB drive and saved the cloned image on a separate drive before proceeding with file repair and data recovery.

Data Extraction

Since the files were corrupted and the data recovery process required manual intervention, our experts manually extracted data from the cloned image.

While both Excel and Word files were affected, the most critical business data was stored in Excel spreadsheets, which required extensive manual repair.

File Repair

During the corrupted file recovery process, our experts carefully examined the internal structure of the damaged Excel files. Using specialized tools, Stellar’s data recovery team analyzed the internal file architecture (the ZIP-based container architecture used by .xlsx files). As part of the analysis, the following components were examined:

• xml
• Sheet data
• Shared strings
• Styles and metadata

Our experts manually extracted the worksheets, charts, and formulas. We then rebuilt the damaged worksheet structure, restored sheet relationships and indexing. Finally, the corrupted cell references were reconstructed.

Verification and Data Delivery  

We shared the preview of the repaired Excel file with the client for verification. After receiving then client’s approval, the recovered Excel was delivered on a separate encrypted hard drive.

While this case highlights a successful corrupted file recovery, here’s another customer sharing their experience with Stellar Data Recovery after recovering critical data.

Wrap Up

Our client felt relieved when he received the repaired files in minimal downtime. The client expressed gratitude, as the sudden inaccessibility of critical data had disrupted both their domestic and international projects. The key takeaway from this case is that a zero bytes or inaccessible Excel file does not necessarily mean permanent data loss. Through systematic drive scanning, advanced corrupted file recovery techniques, and manual data extraction, Stellar Data Recovery successfully restored data and helped the client resume operations quickly. This case reinforces the importance of relying on experienced data recovery professionals during data loss situations.
