Recovery Software Saved Files Back to Your Drive
If you ran EaseUS, Recoverit, Disk Drill, or Stellar and the software saved recovered files back onto the same drive you were trying to recover, the original data at those sectors is now overwritten. Every file the software wrote destroyed another file you were trying to save.
How much data survives depends on how far the write-back went before it was stopped. PC-3000 Data Extractor can carve surviving files from untouched sectors using raw signature scanning. HDD recovery from $100. SSD recovery from $200. No data, no fee.
What Happens When You Save to the Source Drive
When a file is deleted on an NTFS volume, the operating system does not erase the data from the platters or NAND cells. It updates two metadata structures: the Master File Table ($MFT), which tracks every file and folder on the volume, and the $Bitmap, which maps cluster allocation status. The clusters that held the deleted file are marked "free" but still contain the original data.
Consumer recovery software scans these metadata structures to find deleted files. When the software saves recovered files back to the same drive, the operating system writes that output into clusters marked as free. Those free clusters contain the deleted files the user is trying to recover. The software extracts File A and writes it over the sectors holding File B. Each file saved destroys another file.
The $MFTMirr Does Not Back Up Your Files
A common assumption is that the NTFS Master File Table Mirror ($MFTMirr) contains a full backup of the file system. It does not. The $MFTMirr stores copies of only the first four MFT records: $MFT, $MFTMirr, $LogFile, and $Volume. Its purpose is to let the operating system locate the MFT itself if there is a single-sector read failure at the beginning of the partition.
If consumer software write-back operations overwrite the bulk of the $MFT, the folder hierarchy, file names, and timestamps for every user file are permanently destroyed. The $MFTMirr cannot restore them. This is why write-back damage is more destructive than a quick format; a quick format creates a new empty $MFT of roughly 256 KB, killing records for the first ~229 files but leaving the rest of the disk untouched. Write-back actively fills sectors across the entire volume.
Consumer Software That Triggers This Problem
Most consumer recovery applications warn users not to save to the source drive. The warnings are easy to miss when a user is panicking over lost files. These tools are the most common sources of write-back overwrite damage we receive at the lab:
- 1.Wondershare Recoverit allows users to select any connected drive as the output destination. Wondershare's own documentation notes that writing data back to the same disk covers and erases original data permanently.
- 2.EaseUS Data Recovery Wizard displays a warning dialog, but users dealing with an external drive failure often select the original drive letter as the output destination out of habit.
- 3.Disk Drill includes "Data Protection" vaults, but standard recovery operations still allow users to drag recovered files to any location, including the source drive.
- 4.Stellar Data Recovery presents a save dialog that defaults to the user's Documents folder, but does not block selection of the source drive as the output path.
Write-Back Damage on HDDs vs. SSDs
Hard Disk Drives
On conventional CMR (Conventional Magnetic Recording) hard drives, overwritten sectors are permanently lost. Sectors the software did not reach remain readable. The ratio of recoverable data depends on how much was written back before the process was stopped.
Modern consumer HDDs using Shingled Magnetic Recording (SMR) present an additional complication. SMR drives use an internal translation layer similar to SSDs. When consumer software begins writing recovered files back to an SMR drive, the translation layer may reorganize adjacent data bands in the background, destroying unallocated data beyond the immediate overwrite footprint. This expands the damage radius beyond what the user actually wrote.
Hard drive data recovery after partial write-back starts at $250 (file system tier).
Solid State Drives
Write-back on modern SSDs triggers a secondary destruction mechanism. The TRIM command tells the SSD controller that deleted blocks are no longer needed. The controller's garbage collection then physically erases those NAND cells to maintain write performance. Keeping the drive powered on while running consumer software gives the garbage collection time to zero out unmapped cells.
Unless the specific SSD controller is supported by PC-3000 SSD for Techno Mode or Factory Mode intervention, recovering overwritten data on a modern SSD after TRIM execution is not feasible. Drives using Apple T2 or M-series silicon bind NAND encryption keys to the Secure Enclave; chip-off recovery is not possible on these devices regardless of overwrite status.
SSD data recovery from $200. Read more about why recovery software fails on dead SSDs.
How We Assess Write-Back Damage in the Lab
When a drive arrives with suspected software write-back damage, our technicians use the PC-3000 Data Extractor to evaluate how much of the NTFS metadata survived.
- 1MFT and $LogFile examination. Data Extractor runs a Scan MFT+INDX operation to determine whether any fragments of the original file tree survived. The $LogFile, which records NTFS transactions, reveals the extent and timing of the overwrite operations.
- 2Overwrite footprint mapping. The technician maps which LBA ranges were written during the write-back session. Sectors outside the overwrite footprint still hold original data.
- 3RAW recovery (signature carving). If the $MFT is destroyed beyond reconstruction, logical file tree recovery is not possible. Data Extractor switches to RAW recovery mode, scanning the physical sectors for known file headers (e.g.,
0xFFD8FFfor JPEG,0x504B0304for ZIP/DOCX). This process recovers files without names, dates, or folder structure.
Limitations of RAW File Carving
RAW signature carving is the last resort when the file system metadata is gone. It works by matching hex patterns in raw sectors to known file format signatures. Results depend on two factors:
What RAW carving can recover
- ✓Contiguous files (photos, PDFs, simple documents) stored in sequential sectors
- ✓File types with well-defined headers and footers (JPEG, PNG, MP4, ZIP)
- ✓Data from sectors outside the overwrite footprint
What RAW carving cannot recover
- ✗File names, creation dates, or folder structure (stored in the destroyed $MFT)
- ✗Fragmented files split across non-contiguous sectors
- ✗Sectors physically overwritten by write-back data
- ✗SSD data erased by TRIM and garbage collection
Pricing
Software overwrite damage is a logical corruption problem. For HDDs where the write-back was stopped early, recovery falls in the file system tier ($250 and up). Drives with extensive overwrite damage requiring RAW carving across the full surface are priced in the firmware tier ($600-$900). SSD recovery after write-back depends on controller support and TRIM status.

Hardware Repair vs. Software Locks
Our "no data, no fee" policy applies to hardware recovery. We do not bill for unsuccessful physical repairs. If we replace a hard drive read/write head assembly or repair a liquid-damaged logic board to a bootable state, the hardware repair is complete and standard rates apply. If data remains inaccessible due to user-configured software locks, a forgotten passcode, or a remote wipe command, the physical repair is still billable. We cannot bypass user encryption or activation locks.
No data, no fee. Free evaluation and firm quote before any paid work. Full guarantee details. Head swap and surface damage require a 50% deposit because donor parts are consumed in the attempt.
Target drive: The destination drive we copy recovered data onto. You can supply your own or we provide one at cost. For larger capacities (8TB, 10TB, 16TB and above), target drives cost $400+ extra. All prices are plus applicable tax.
