HDD / SSD TRIM File Overwrite & Bad Sector Data Recovery Estimator
Calculate data recovery probability after file deletion, disk formatting, or partition corruption. Simulates SSD background TRIM deallocation, HDD magnetic sector overwrites, file system journaling traces, and carving feasibility.Documentation & FAQs ↓
Storage Drive Data Recovery & Overwrite Forensics
Model SSD TRIM commands, NAND garbage collection, HDD magnetic retention, and forensic recovery likelihood.
Unmount filesystem immediately to prevent OS paging or SSD TRIM sweeps. Create a read-only bitstream clone image (.img) using ddrescue before running TestDisk or PhotoRec carving.
Step-by-Step Instructions
4 Steps to CompletionSelect your physical drive media type: NVMe/SATA SSD, traditional mechanical HDD, USB flash drive, or SD memory card.
Specify the deletion scenario: simple trash empty, quick format, deep format, partition table loss, or physical clicking/bad sectors.
Enter drive operational parameters: time elapsed, operating system power-on state, and estimated gigabytes written since deletion.
Review the statistical recovery probability score (0%–100%), failure risks, and recommended immediate forensic actions.
Practical Use Cases & Real-World Scenarios
SSD TRIM vs Magnetic HDD Forensic Physics Engine
Evaluates fundamental hardware differences—modeling how SSD flash controller garbage collection zeroes deleted blocks compared to magnetic HDD remnant sectors.
Storage Device Overwrite Entropy Model
Computes recovery survival odds based on gigabytes written to the partition since the deletion event, factoring in total partition capacity and free space.
File System Metadata & Journaling Traces
Analyzes master file table (NTFS MFT, ext4 journal, APFS container) survival odds vs fragmented file carving reconstruction.
Targeted Action Plan & Recovery Urgency Guide
Generates immediate step-by-step containment instructions (unmounting drive, read-only imaging, freezing TRIM) to maximize salvage odds.
