Forensic Data Recovery & Evidence Authentication

Deleted files, damaged drives, disputed documents, suspicious emails. The Waldrep Company provides forensic data recovery and authentication of digital records for attorneys nationwide, documented at every step so the work stands up to examination.

Two questions bring attorneys here: can the data be recovered, and can this record be trusted? Our forensic data recovery work retrieves deleted, corrupted, and formatted data from computers, phones, and storage media while preserving the original evidence. Our authentication work examines emails, documents, photos, and chat records to determine whether they are what they claim to be.

This is not consumer data recovery. A repair shop can pull photos off a dead drive, but it does not document methods, verify results with hash values, or maintain chain of custody, and those gaps become the other side's cross examination. Every engagement is led by Eric L. Waldrep, MCFE, with 19 years in digital forensics and 27 years in law enforcement.

Common Matters

Altered contracts, disputed messages in custody matters, vanished files in employment cases, contested photos in insurance claims, and intellectual property theft. When the work uncovers a broader problem, it can expand into a full digital forensics investigation.

Recover the Evidence. Prove Its Integrity.

Recovery and authentication documented well enough to survive the other side's expert, not just files on a thumb drive.

Forensic Data Recovery

Recovery from HDDs, SSDs, USB drives, SD cards, and RAID arrays using write-protected forensic techniques with hash verification.

Email Authentication

Analysis of email headers, routing information, and metadata to verify sender, timestamp, and transmission path.

Photo & Video Authentication

EXIF metadata, hash comparison, and compression analysis to verify whether photos and videos are original or altered.

Chain of Custody

Every engagement is documented with hash values, methodology notes, and evidence handling records.

Deleted File Recovery: What Comes Back and What Is Gone

An honest scoping answer before you spend money beats a hopeful one after.

Deleting a file usually does not erase it; the operating system just marks the space as available. Until something overwrites that space, the file, or pieces of it, can often be recovered and verified with hash values.

What matters is what happened after the deletion. A drive that kept running for months has overwritten more than one powered off the same day, and modern SSDs clear deleted data in the background through TRIM, sometimes within minutes.

The honest answer to "can you get it back" is: sometimes, and we can usually tell you early. After a preliminary review we will say, in writing, what is realistically recoverable, what is partial, and what is gone. Proof that data no longer exists, and roughly when it stopped existing, can matter as much as the data itself.

Frequently Recoverable

  • Recently deleted files on hard drives and flash media
  • Deleted photos and videos on memory cards
  • Files in unallocated space, recycle bins, and shadow copies
  • Data on drives after a quick format

Usually Gone

  • Data overwritten by new files
  • SSD data after TRIM has cleared it
  • Securely wiped data (the wiping itself leaves traces)
  • Media physically damaged beyond lab repair

How We Authenticate Digital Evidence

A record is not evidence because it looks right. Its origin and integrity have to hold up under examination.

Metadata Analysis

Every file carries data about itself: timestamps, author fields, device identifiers, editing history, GPS coordinates in photos. Metadata analysis compares what a file says about itself against what the surrounding system says. A document supposedly written years ago that carries last month's internal timestamps has already answered the question.

Hash Verification

A hash value is a mathematical fingerprint: two files with matching hashes are identical to the bit. Hashes confirm a produced copy matches the original, detect substitution between productions, and show nothing changed while the evidence was in our custody.

Provenance

Where has this record been? We trace a file back through the mailbox, device, server, or cloud account that created and stored it. A record with an unbroken provenance trail is far harder to attack than one that surfaced as an attachment with no history.

Detecting Fabrication and Backdating

Forged records betray themselves in the details: software versions that postdate the claimed date, timestamps that conflict across metadata fields, editing artifacts, missing companion records. A genuine file leaves traces in more than one place, and a fake rarely covers them all. Findings go into a forensic report or declaration the opposing expert can check step by step.

Email Authentication: Headers, Routing, and Timestamps

A printout shows what a message looked like, not where it came from.

Email is the most commonly disputed record we see. Email authentication starts with the full headers: the routing chain each server stamped on the message, timestamps across time zones, Message-ID values, and DKIM signatures where they exist. A fabricated message has to fake all of it consistently, and most do not.

For discovery, request native email (PST, MBOX, or EML with full headers), not PDFs or forwards. Forwarding rewrites the very headers an examiner needs.

What an Email Examination Can Address

  • Whether headers are consistent with the claimed transmission path
  • Whether timestamps align across the servers that handled the message
  • Whether a message exists in the counterpart mailbox
  • Whether content was altered after receipt

Screenshots vs. Native Files: Ask for the Real Thing

A screenshot is a photograph of a screen. Treat it accordingly.

A screenshot carries none of the message's metadata, cannot be hash-verified against any source, and can be faked in minutes with a basic image editor or an AI tool. When the other side produces a screenshot of a text thread, you are being asked to trust a picture.

How a particular court treats screenshots is a question for counsel, not for us. What an examiner can do with one is very little: the image alone cannot confirm when a message was sent, whether the thread was edited, or whether the conversation existed at all.

What to Request Instead

  • A forensic extraction of the device that sent or received the messages
  • Native files with metadata intact, not printouts or PDFs
  • Mailbox exports (PST, MBOX) rather than forwarded copies
  • The application databases that store the original chat records

Spoliation and Destruction Analysis

When data disappears at a convenient moment, the destruction itself becomes evidence.

We examine devices and accounts for signs of deliberate destruction: wiping utilities installed and run, factory resets, mass deletions in a narrow window, log gaps, and cloud sync activity that removed files from every linked device.

Timing is usually the heart of it: artifacts often place the destruction on a timeline against the events of the case, and destruction that lines up with a demand letter reads differently from routine housekeeping.

We are direct about limits: showing a device was wiped is often possible, while showing whose hands did it depends on the surrounding evidence. Findings are documented for motions practice, and expert witness testimony is available when the dispute goes further.

Destruction Indicators We Look For

  • Wiping utility installation, execution, and uninstall traces
  • Factory reset timestamps on phones and tablets
  • Mass deletions clustered around key case dates
  • USB devices connected around the deletion window
  • Cloud sync and trash records showing what left the account

Frequently Asked Questions

What can be recovered, what can be proven, and what it costs.

Sometimes. Permanently deleted usually means a file no longer appears in a trash folder, not that the data is erased. Deleted files on hard drives and memory cards often survive until new data overwrites them; modern SSDs and smartphones can clear them within minutes. We assess recoverability early, before significant fees accrue.
In many cases, yes. Fabricated and backdated records tend to leave inconsistencies: internal metadata that conflicts with the claimed date, headers that do not match a real transmission path, or missing companion records a genuine file would have created. We cannot promise a definitive answer in every matter, but we can usually determine whether a record's story holds together.
Admissibility is a legal question for counsel and the court, so treat this as general education, not legal advice. Forensically, a screenshot is weak: a picture of a screen with no metadata of its own, impossible to hash-verify against a source, and easy to fabricate. Where possible, request the native file, the mailbox export, or a forensic extraction of the device instead.
We can often show that wiping occurred, when it occurred, and what tool or method was used. Wiping utilities leave installation and execution traces, factory resets leave timestamps, and log gaps are themselves observable. Tying the wiping to a specific person's hands depends on the surrounding evidence, and we are candid about that limit.
