The process begins with a preliminary conversation about the device, what happened, and which information is most important to the customer.

We may ask:

• What type of device or storage media is involved?

• What happened immediately before the data became unavailable?

• Were files deleted, was the device formatted, or did it become inaccessible?

• Is the device still recognized by a computer?

• Does it click, grind, beep, repeatedly disconnect, or show signs of physical damage?

• Has recovery, repair, or disk-management software already been used?

• Was the device used after the data loss occurred?

• Which files, folders, dates, or categories of information are most important?

• Is the device encrypted or password protected?

• Is there a deadline associated with the requested recovery?

The purpose of this consultation is to determine whether the request appears consistent with logical data recovery, whether immediate precautions are necessary, and whether an in-person device evaluation should be scheduled.

Please provide only general, nonsensitive information through the website consultation form. Do not submit passwords, encryption keys, recovery codes, financial-account information, government identification numbers, confidential evidence, private file contents, or complete system logs through the public form or ordinary email.

The initial consultation does not establish a service agreement, authorize examination of the device, guarantee acceptance of the matter, or guarantee that recovery will be possible.

Before a device is examined, Frederick Data Forensics confirms that the customer owns the device or has documented legal authority to authorize the requested work.

Proof of identity, ownership, or authorization may be requested. A family relationship, workplace relationship, possession of a device, or knowledge of an account does not automatically establish authority to access its contents.

The intake process may document:

• Customer identity and contact information

• Device or media type

• Manufacturer and model

• Serial number or other available identifiers

• Reported storage capacity

• Apparent physical condition

• Included cables, adapters, enclosures, or accessories

• Reported data-loss circumstances

• Previous recovery or repair attempts

• Requested files, folders, date ranges, or categories of information

• Authorized scope of work

• Delivery and contact preferences

• Date and time the device was received

The device is assigned a case or intake identifier. Photographs may be taken to document its condition, identifying information, and included items at the time of receipt.

The customer and Frederick Data Forensics will document the authorized evaluation scope, applicable fees, known limitations, handling instructions, and customer responsibilities before technical work begins. Authorization for an initial evaluation does not automatically authorize unrestricted examination, remediation, or a complete recovery attempt.

Any password, encryption key, or recovery credential legitimately required for accepted work will be handled through a separately agreed process. Sensitive credentials should not be submitted through the public consultation form or ordinary email.

Before applying power, the exterior of the device, enclosure, connectors, and other safely accessible components are inspected for conditions that could make connection unsafe or place the data at additional risk.

The inspection may look for:

• Bent, broken, loose, or burned connectors

• Cracked or damaged enclosures

• Evidence of impact or crushing

• Liquid exposure or corrosion

• Signs of overheating or electrical damage

• Loose components or unusual movement inside an enclosure

• Evidence that a sealed hard drive was previously opened

• Missing, damaged, or incompatible cables or adapters

• Mechanical-failure symptoms reported by the customer

A sealed hard drive is not opened during this inspection.

If a device clicks, grinds, beeps, repeatedly attempts to spin, has sustained significant physical damage, or otherwise shows signs of mechanical or electrical failure, the evaluation may stop without applying power or without performing additional power cycles. Repeatedly powering an unstable device can worsen the damage and reduce the possibility of later recovery.

Frederick Data Forensics, L.L.C. does not perform clean-room recovery, platter repair, read/write-head replacement, motor repair, circuit-board repair, microsoldering, or other invasive physical-drive work.

A device requiring those capabilities may be declined or referred to a specialized physical-recovery laboratory. When possible, the customer will receive a clear explanation of why continued logical recovery is not recommended.

If the device appears suitable for non-invasive evaluation, it is connected using an appropriate interface, controlled power source, and hardware write-blocker when the device type, connection, and condition support an appropriate write-blocked path.

A hardware write-blocker allows the forensic workstation to read compatible source media while helping prevent the workstation or operating system from writing changes back to the customer’s device.

Before substantive access begins, we confirm that:

• The customer device is correctly identified as the source

• Destination storage is separately identified

• The source is connected through the intended protected path

• The write-blocker reports the expected read-only condition

• Recovery output is directed to separate destination storage

• The source and destination are not inadvertently reversed

• Automatic operating-system actions are limited or disabled where appropriate

Frederick Data Forensics does not intentionally initialize, format, defragment, repartition, or write recovered files to the original device as part of the standard evaluation process.

Automatic-repair utilities such as CHKDSK are not intentionally run against the original device during the standard protected evaluation. Although such utilities may attempt to repair file-system structures, they can modify the source and complicate later recovery or forensic examination.

Not every device can be connected through the same write-blocker. Certain USB devices, encrypted devices, proprietary enclosures, mobile devices, damaged interfaces, or other specialized media may require a different acquisition method. Any material departure from the standard protected workflow must be technically appropriate, documented, and authorized before proceeding.

Appropriate acquisition and examination tools are used to determine whether the device can be identified, accessed, and read through the selected protected connection.

The technical assessment may document or review:

• Reported manufacturer, model, and serial number

• Reported storage capacity

• Logical and physical sector sizes

• Partition layout

• Recognized file systems

• Missing or damaged partition information

• Allocated, unallocated, or inaccessible space

• Indicators of encryption

• Connection stability

• Device resets or unexpected disconnections

• Read errors or inaccessible areas

• Available drive-health information

• Whether continued acquisition appears technically appropriate

When supported by the device and connection method, available Self-Monitoring, Analysis and Reporting Technology—commonly called SMART—information may be reviewed as one indicator of drive condition.

SMART information is not a guarantee that a drive is healthy. A device may report acceptable values while still containing unreadable sectors, experiencing intermittent failures, or approaching mechanical or electronic failure.

Testing is limited to what is reasonably necessary to determine whether continued acquisition or logical recovery is appropriate. A complete surface scan, repair operation, stress test, or repeated full-device read is not automatically performed because unnecessary access can place additional strain on unstable media.

If the device becomes unstable, begins producing significant errors, disconnects repeatedly, or exhibits symptoms suggesting physical failure, the assessment may be paused or stopped. The customer will be informed of the observed condition and available options before additional work proceeds.

The intake information and technical observations are used to classify the apparent problem as closely as reasonably possible and determine whether the device appears suitable for continued logical-recovery work.

A likely logical-data problem may involve:

• Accidental file deletion

• Quick-formatted storage media

• A deleted, damaged, or inaccessible partition

• Missing or damaged file-system records

• An inaccessible but otherwise readable file system

• Missing files on operational storage media

• Recoverable data remaining in unallocated space

The evaluation may conclude that:

• The device appears suitable for logical recovery

• Recovery may be possible, but significant limitations exist

• Additional destination storage is required

• A password, encryption key, or recovery credential is required

• The device is too unstable for continued logical work

• Physical, mechanical, or electronic failure is suspected

• A specialized physical-recovery laboratory should be considered

• The requested work falls outside the company’s current capabilities

• Available information does not support a reasonable recovery attempt

The customer will receive a plain-language explanation of the material observations, known limitations, proposed next step, applicable fees, and any significant risks associated with continuing.

Work does not proceed beyond the previously authorized evaluation scope without the customer’s approval. Authorization to evaluate a device does not automatically authorize forensic imaging, a complete recovery attempt, remediation, additional expense, or examination beyond the categories of information identified in the agreed scope.

A favorable evaluation means only that a logical recovery attempt appears technically reasonable. It does not guarantee that requested files remain available, intact, identifiable, or usable.

When the device appears sufficiently stable and the customer authorizes continued work, the preferred next step is to create a sector-level forensic image or another controlled working copy appropriate to the device and recovery objective.

The normal acquisition path is:

Original device → hardware write-blocker → forensic workstation → protected destination storage

Forensic acquisition software reads accessible information from the source and writes the resulting image or copy to separately identified destination storage. Recovery analysis is then performed from that image or working copy whenever practical, reducing repeated interaction with the original device.

Depending on the device, condition, authorized scope, and selected acquisition method, the result may be stored as:

• An Expert Witness Format image, such as E01

• A raw sector image

• A device-to-device controlled copy

• A logical acquisition of specifically authorized files or folders

• Another technically appropriate acquisition format

The acquisition record may document:

• Customer and case identifier

• Source-device information

• Destination-storage information

• Examiner

• Date and time acquisition began and ended

• Connection and write-blocking method

• Acquisition tool and relevant version information

• Selected image or copy format

• Total data processed

• Read errors, inaccessible areas, or interrupted regions

• Cryptographic hash values when generated

• Significant warnings, interruptions, or examiner observations

If the device becomes unstable, produces substantial read errors, disconnects repeatedly, or develops symptoms of physical failure, acquisition may be paused or stopped to reduce the risk of additional damage.

A completed image or working copy represents the information that could be read through the selected method. It does not guarantee that every source sector was accessible or that every file contained within the acquisition is complete, identifiable, or recoverable.

Cryptographic hash values may be generated to document the integrity and consistency of a forensic image, controlled working copy, recovered file, exported record, or other significant case material.

A cryptographic hash functions as a digital fingerprint calculated from the content of the information being examined. If two independently calculated hash values match, that result helps demonstrate that the compared data remained unchanged between those calculations.

Depending on the acquisition method and authorized scope, integrity verification may include:

• Hash values calculated during acquisition

• Verification values calculated after acquisition

• Comparison of acquisition and verification results

• Hashes for individual exported or recovered files

• Hashes for reports or delivery packages

• Documentation of the algorithm used

• Documentation of any mismatch, interruption, or verification limitation

Commonly used algorithms may include SHA-256 or another technically appropriate cryptographic-hash algorithm. The selected algorithm and resulting value may be recorded in the case documentation.

Matching hash values help demonstrate consistency between the specific items compared. They do not establish that:

• Every sector of a damaged source device was readable

• Every source file was present in the acquisition

• A recovered file is complete or uncorrupted

• The original device was free from preexisting damage

• The information is accurate, truthful, or authentic in every broader sense

• The customer’s requested data can be successfully recovered

If read errors, inaccessible sectors, acquisition interruptions, tool limitations, or other conditions affect verification, those limitations will be documented when material to the engagement.

Recovery analysis is performed from the forensic image or controlled working copy whenever practical. The methods used depend on the device, file system, reported data-loss circumstances, requested information, and authorized scope.

Analysis may include:

• Reviewing the partition structure

• Identifying deleted, damaged, or inaccessible partitions

• Examining available file-system records

• Reviewing allocated and unallocated space

• Locating deleted file entries

• Searching for requested filenames, dates, folders, or file types

• Reconstructing available folder relationships

• Comparing results from multiple recovery methods

• Performing file-signature analysis

• Identifying apparently incomplete, corrupted, or overwritten files

• Separating responsive results from unrelated material when practical

Tools may include FTK Imager, Autopsy, The Sleuth Kit, hashing utilities, file-system analysis tools, and other appropriate acquisition or recovery software. Tool selection depends on the technical circumstances, and no single program is relied upon for every device or recovery matter.

Deleted Files

Deleting a file often removes or changes the file system’s reference to that file without immediately overwriting all of its underlying content.

Recovery may be possible when the original data has not been overwritten, securely erased, trimmed, or otherwise cleared. A recovered file may nevertheless have:

• A missing or generic filename

• No original folder path

• Incomplete or inaccurate metadata

• Corrupted or overwritten sections

• Missing fragments

• Partial or unusable content

Continued use of a device after deletion increases the likelihood that recoverable information will be overwritten. SSD behavior, including TRIM and garbage collection, may substantially reduce the possibility of recovering deleted data even when little additional user activity has occurred.

Formatted Media

A quick format may replace or recreate file-system structures without immediately overwriting every underlying data block. Depending on the device, file system, formatting method, and subsequent use, some information may remain recoverable.

Recovery may be substantially reduced or prevented when:

• A full format was performed

• A secure-erasure or sanitize function was used

• New files were saved afterward

• An operating system was installed or reinstalled

• Encryption prevents access

• SSD TRIM or garbage collection cleared relevant blocks

• The storage media is physically damaged or unstable

File-Signature Recovery

When useful file-system records are unavailable, file-signature analysis—sometimes called file carving—may identify content using recognizable internal structures associated with known file types.

File-signature recovery may recover file content without recovering the original:

• Filename

• Folder location

• Creation, modification, or access dates

• File-system metadata

• Relationship to surrounding files

Fragmented, partially overwritten, corrupted, encrypted, compressed, proprietary, or unsupported files may remain incomplete or unusable.

Recovery results are evaluated in context. The presence of a recognizable file signature does not by itself guarantee that the entire file was recovered correctly or that its content is responsive to the customer’s request.

Potentially recovered files are reviewed to determine whether they appear consistent with the requested file types and are reasonably suitable for delivery.

Validation may include:

• Confirming the apparent file type

• Reviewing file headers or internal structure

• Opening an appropriate sample of recovered files

• Identifying zero-byte, truncated, or visibly corrupted files

• Comparing results with requested filenames, dates, folders, or categories

• Separating apparently complete and incomplete results

• Reviewing whether expected applications can recognize selected files

• Generating cryptographic hash values when appropriate

Validation does not mean that every recovered file is manually opened, viewed in full, or independently verified for substantive accuracy. A file that opens successfully may still contain missing, overwritten, altered, or corrupted content.

Delivery

Recovered files are copied to clean destination media or delivered through another method documented and approved for the engagement. Recovered information is not intentionally restored to the original source device.

Before delivery, the customer and Frederick Data Forensics may establish:

• The approved destination device or delivery method

• Required storage capacity

• Whether deliverables should be encrypted

• How any delivery password will be communicated

• Who is authorized to receive the results

• The customer’s responsibility for promptly reviewing and backing up the delivered information

Customers should verify the delivered data and create an independent backup before relying on it as the only remaining copy.

Case Summary

The customer may receive a written service or case summary documenting:

• The device or media examined

• The reported data-loss circumstances

• The authorized scope

• The general methods and tools used

• Whether a forensic image or controlled working copy was created

• Significant read errors, interruptions, or technical limitations

• General recovery and validation results

• The destination containing the delivered information

• Material actions performed

• Recommendations for handling the original device and delivered data

• The applicable customer-data review and retention period

Delivery of recovered information does not guarantee that every requested file was recovered, that every delivered file is complete, or that the original device should be returned to service.

Data recovery is inherently uncertain. No recovery method can recreate information that has been completely overwritten, securely erased, physically destroyed, or rendered inaccessible by unavailable encryption credentials.

Recovery may be limited or prevented by:

• Continued use of the device after data loss

• Overwritten storage areas

• SSD TRIM or garbage collection

• Secure-erasure or sanitization procedures

• Full formatting

• Encryption without the required password or recovery key

• File-system corruption

• Physical, mechanical, electrical, fire, or liquid damage

• Unreadable sectors or unstable media

• Fragmented or partially overwritten files

• Unsupported or proprietary file formats

• Previous recovery or repair attempts

• Missing, damaged, or recreated file-system metadata

• Operating-system reinstallation or substantial new data being written

A recovery attempt does not guarantee:

• Recovery of a particular file

• Recovery of every requested file

• Recovery of a particular percentage of the device

• Preservation of original filenames or folder relationships

• Preservation of all dates or metadata

• Complete, readable, or corruption-free content

• Continued stability of the original device

• Successful recovery from every readable sector

• That apparently recovered information contains the content expected by the customer

• That the original device can safely return to normal use

Estimates or preliminary observations describe technical conditions at the time of evaluation. They do not constitute a guarantee of the final recovery result.

Frederick Data Forensics, L.L.C. provides a documented, good-faith technical effort based on the authorized scope, condition of the available media, accessible information, selected methods, and current capabilities.

If continued logical recovery is not technically appropriate, the customer will receive a clear explanation and may be advised to consider a specialized physical-recovery laboratory or another qualified provider.
