Copying files or running recovery software directly on it was not an option.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The drive stored more than office documents. It also stored photographs, videos, and program files from the client\u2019s ongoing housing project.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">No other copy existed, which made the original drive the only source of the data.<\/span><\/li>\n<\/ul>\n<\/div>\n<h2 class=\"mt-3\"><b>The Data Recovery Approach by Stellar Hyderabad<\/b><\/h2>\n<p data-pm-slice=\"1 1 []\">Stellar follows a tailored data recovery approach based on the nature and complexity of each case. This Stellar SSD data recovery case involved assessing severe media degradation, cloning the unstable SSD, analysing NTFS file system corruption, and reconstructing the recoverable files. The process followed five stages.<\/p>\n<h3><b>1. Media Analysis<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The Engineering and Innovation team performed a routine media inspection to assess the physical health and determine why it wasn&#8217;t detected. The inspection found extensive bad blocks, serious media degradation, and damage to the file system structures. The drive was too unstable to read directly, which ruled out standard file copying and software-based recovery.<\/span><\/p>\n<h3><b>2. Disk Cloning<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The team cloned the SSD block by block onto a healthy drive using specialised equipment designed for unstable media. The objective was to read as much data as possible without further damaging the source drive. Because of the large number of bad blocks, the cloning took a couple of days. The original SSD was not used again, and all recovery work was done on the clone.<\/span><\/p>\n<h3><b>3. Cloned Image Analysis<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The analysis showed heavy damage to the file system metadata, including the <strong>master file table (MFT)<\/strong>, which the operating system uses to locate files and folders. Bad blocks on the source drive corrupted the MFT, which left the operating system unable to rebuild the original folder structure through normal means.\u00a0<\/span><\/p>\n<h3><b>4. Data Carving and File Reconstruction<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">With the NTFS file system damaged, the team carved the data manually using proprietary tools. The main steps are listed below.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The team identified file signatures and data patterns in the raw data and extracted the recoverable content.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Engineers reassembled files that had fragmented into multiple blocks.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The team sorted the recovered files by type, including documents, photographs, videos, and program files.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The team restored original folder structures and file names for every file with enough surviving metadata.\u00a0<\/span><\/li>\n<\/ul>\n<h3><b>5. Integrity Verification<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Every recovered file was checked before delivery. The main checks are listed below.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Experts opened the files in their supported formats to confirm that they were accessible and working.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">File sizes and structural consistency were verified for each file type.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Incomplete or partly damaged files were identified and separated from the usable ones.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Folder structures and file names were reviewed to confirm that they matched the recovered content.<\/span><\/li>\n<\/ul>\n<div class=\"green_note\">\n<h2><strong>The Result<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">Stellar Hyderabad experts recovered the data the client required from the failing SSD. The outcome is listed below.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The recovered data included Word documents, Excel spreadsheets, PDF files, project and program files, photographs, and videos.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">All files were transferred to an encrypted hard drive and delivered to the client, which allowed administrative work and ongoing projects to resume.<\/span><\/li>\n<\/ul>\n<\/div>\n<h2><b>Why Cloning First Made the Difference in This SSD Recovery<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">The order of recovery steps matters as much as the tools. An SSD with many bad blocks is fragile, and every read attempt on the original drive puts the remaining data at risk. Repeated connections, running recovery software directly on the drive, or a vendor working on the original media can all reduce the amount of data that can be recovered.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Stellar Hyderabad experts avoided this risk by cloning the drive first and carrying out every later step on the copy. Cloning took a couple of days, but it protected the original media from further strain. File reconstruction from raw data after the NTFS failure and the integrity checks before handover were then completed on the clone, which left the failing SSD untouched.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Behind every undetected SSD are years of work, project files, and memories waiting for a second chance.
