When you first contact DriveSavers, an advisor gathers key details: what type of device you have (hard drive, SSD, RAID or NAS, smartphone, tablet, USB flash drive, camera card, or other storage), what platform it was used with (Mac, Windows, mobile, or a server), and what details you can give about the data loss situation.<\/p>\n<p>You\u2019ll be asked about symptoms such as drops, liquid spills, power events, unusual noises, error messages, or a volume suddenly going offline, along with any previous repair or recovery attempts. This initial conversation sets expectations and gives engineers a roadmap for the safest way to handle your case once the device arrives.

Throughout this process, security procedures are followed to ensure the device and data are handled in accordance with industry security certifications.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><div class=\"vc_tta-panel\" id=\"1716892470635-67dc37f4-23f5\" data-vc-content=\".vc_tta-panel-body\"><div class=\"vc_tta-panel-heading\"><h4 class=\"vc_tta-panel-title vc_tta-controls-icon-position-right\"><a href=\"#1716892470635-67dc37f4-23f5\" data-vc-accordion data-vc-container=\".vc_tta-container\"><span class=\"vc_tta-title-text\">Non-Destructive Evaluation and Diagnosis<\/span><i class=\"vc_tta-controls-icon vc_tta-controls-icon-chevron\"><\/i><\/a><\/h4><\/div><div class=\"vc_tta-panel-body\"><div class=\"vc_row wpb_row vc_inner vc_row-fluid wpex-relative no-bottom-margins\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n\t<div style=\"color:#6f737e;font-size:18px;\" class=\"wpb_text_column has-custom-color wpex-child-inherit-color wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<h5>Initial Power-Up and Safe Testing<\/h5>\n<p>After the device is logged and inspected, engineers move to a controlled power-up. The device is connected to specialized diagnostic systems that safely read the media without modifying it.<\/p>\n<p>Here, the focus is on behavior under power: Does the device run reliably? Do the tools see it at a low, hardware level, even if the computer can\u2019t mount a volume? Are there timeouts, error codes, or obvious read failures? With spinning hard drives, engineers also listen for clicking, grinding, or repeated spin-up cycles that indicate physical issues.<\/p>\n<h5>Distinguishing Logical vs Physical Issues<\/h5>\n<p>Engineers separate <b>logical<\/b> problems from <b>physical<\/b> ones.<\/p>\n<p>Logical problems include organization issues, such as a corrupted file system, accidental deletion, a partition that has been deleted or reformatted, or damaged metadata that normally tells the system where files and folders live. In these cases, the hardware may initialize normally, but the structures on the media no longer make sense to the operating system.<\/p>\n<p>Physical problems involve the underlying hardware\u2014mechanical or electronic failures, damaged components, or broken connectors. Devices that show unstable behavior when powered are treated as physically at risk and moved into a hardware-focused recovery path. Devices that power up cleanly and respond reliably are routed into logical recovery workflows.<\/p>\n<h5>What You Can Expect From the Evaluation<\/h5>\n<p>From your side, the evaluation is about getting clear information before you decide what to do next. After engineers complete their initial testing, they translate their findings into plain language: what type of problem they\u2019re seeing, how it affects access to the data, and whether recovery appears feasible.<\/p>\n<p>If recovery looks possible, we&#8217;ll discuss the situation and provide an estimate for the recovery work, along with a recommended path forward. Data recovery begins only after the evaluation is complete and you have approved to proceed, ensuring you can make an informed decision before the recovery process begins.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><div class=\"vc_tta-panel\" id=\"1778863052482-f4753871-6c0c\" data-vc-content=\".vc_tta-panel-body\"><div class=\"vc_tta-panel-heading\"><h4 class=\"vc_tta-panel-title vc_tta-controls-icon-position-right\"><a href=\"#1778863052482-f4753871-6c0c\" data-vc-accordion data-vc-container=\".vc_tta-container\"><span class=\"vc_tta-title-text\">Preparing the Device for Recovery<\/span><i class=\"vc_tta-controls-icon vc_tta-controls-icon-chevron\"><\/i><\/a><\/h4><\/div><div class=\"vc_tta-panel-body\"><div class=\"vc_row wpb_row vc_inner vc_row-fluid wpex-relative no-bottom-margins\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n\t<div style=\"color:#6f737e;font-size:18px;\" class=\"wpb_text_column has-custom-color wpex-child-inherit-color wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<p>By this point, engineers know how the device behaves when powered on. From here, the process follows one of two paths. If the hardware is damaged or unstable, the case moves into a physical recovery path. If the hardware is healthy but the data is missing or corrupted, it follows a logical recovery workflow. In both cases, the goal is to prepare the device so that the data can be safely extracted in the next step.<\/p>\n<h5>Physical Recovery Path: Stabilizing Damaged Hardware<\/h5>\n<p>When testing shows clear signs of hardware damage or instability, the priority is to stabilize the device just long enough to create an image or clone. Depending on the device and the damage, this may involve replacing failed internal components with compatible parts from our inventory of over 25,000 devices, repairing electronics on the circuit board, or fixing damaged connectors so the device powers up cleanly and communicates with our lab tools.<\/p>\n<p>For smartphones, tablets, and embedded systems with on-board storage, engineers may need to perform micro-soldering directly on the board to access the flash memory. For severely damaged flash-based media, Such as broken USB drives or camera cards, they may remove memory chips and access the raw data. These repairs are temporary and purpose-built to give engineers a window of time to recover as much readable data as possible.<\/p>\n<p>When a hard disk drive must be opened, that work is done in a tightly controlled cleanroom. DriveSavers operates <a href=\"https:\/\/drivesaversdatarecovery.com\/da-dk\/why-us\/certified-iso-class-5-cleanroom\/\">Certified ISO Class 5 Cleanrooms<\/a> designed to protect delicate drive internals from microscopic contamination that could scratch platters and destroy data. Flash media and board-level work, such as micro-soldering or chip-off procedures, take place at specialized electronics workstations designed for precision and static protection. Across both types of work, DriveSavers uses advanced diagnostics, including thermal technology and high-resolution X-ray imaging, to evaluate internal damage, confirm suspected component failures, and support complex procedures such as ball grid array (BGA) rework without adding unnecessary stress to fragile media.<\/p>\n<p>This kind of physical recovery is reserved for devices with actual hardware damage or instability, not situations limited to accidental deletion or other software-only issues.<\/p>\n<h5>Preparing for Logical Recovery: When Hardware Is Healthy<\/h5>\n<p>If testing shows the hardware is healthy, but the data is missing or corrupted, engineers proceed with a logical recovery path. Typical logical problems at this stage include corrupted file systems, deleted or reformatted partitions, and damaged metadata\u2014the internal records that map files and folders to locations on the media. Even when a drive, SSD, or other device appears to function normally, the original media is treated as evidence\u2014something that should not be altered.<\/p>\n<p>To protect the device, it is attached to specialized hardware and software configured for read-only access. Engineers observe how it responds and log any errors, slow reads, or unusual behavior, but avoid general-purpose repair tools that might rewrite sectors or \u201cfix\u201d file system structures in place. The goal is to understand what can be safely read, and not to force the device to behave differently. Once the original device is protected, attention shifts to the structures that tell the device where data lives.<\/p>\n<p>Using specialized data recovery tools, engineers analyze these structures at a low level. They can see how partitions are arranged, how directory records link together, and where key file system components should reside, even when the operating system can no longer mount the volume. That analysis guides the next steps in the process, leading to imaging and reconstruction without modifying the original device.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><div class=\"vc_tta-panel\" id=\"1778863083710-8299445d-25d5\" data-vc-content=\".vc_tta-panel-body\"><div class=\"vc_tta-panel-heading\"><h4 class=\"vc_tta-panel-title vc_tta-controls-icon-position-right\"><a href=\"#1778863083710-8299445d-25d5\" data-vc-accordion data-vc-container=\".vc_tta-container\"><span class=\"vc_tta-title-text\">Creating a Clone<\/span><i class=\"vc_tta-controls-icon vc_tta-controls-icon-chevron\"><\/i><\/a><\/h4><\/div><div class=\"vc_tta-panel-body\"><div class=\"vc_row wpb_row vc_inner vc_row-fluid wpex-relative no-bottom-margins\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n\t<div style=\"color:#6f737e;font-size:18px;\" class=\"wpb_text_column has-custom-color wpex-child-inherit-color wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<h5>Sector-by-Sector Imaging<\/h5>\n<p>The next step is to create a bit-for-bit clone. Instead of copying only visible files, our engineers make a sector-by-sector copy of the media, including partitions, file system structures, and areas the operating system can no longer mount.<\/p>\n<p>After a reliable image or clone is created, recovery work is done on that copy, not on the original device. Damaged or unstable hardware can be powered down and preserved while engineers rebuild structures and extract files from the image.<\/p>\n<p>Some providers still run repair tools directly on the original drive or device. At DriveSavers, imaging the device and working from a copy are core parts of the process, reducing the risk of further damage to the original data source.<\/p>\n<h5>Handling Unstable or Damaged Areas<\/h5>\n<p>Not every device will read cleanly from start to finish. When the media is unstable or partially damaged, imaging tools are used with caution. Engineers often start with areas that read cleanly, then return to more difficult regions later, sometimes making multiple passes to recover as much data as the device still yields.<\/p>\n<p>Throughout imaging, proprietary software logs unreadable sectors and recurring error patterns. That information helps the team understand which parts of the file system or files may be affected later. Creating this image can take time on a damaged device, but it provides a safe working copy on which every step in the data recovery process depends.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><div class=\"vc_tta-panel\" id=\"1778863094235-485a2e4c-cae9\" data-vc-content=\".vc_tta-panel-body\"><div class=\"vc_tta-panel-heading\"><h4 class=\"vc_tta-panel-title vc_tta-controls-icon-position-right\"><a href=\"#1778863094235-485a2e4c-cae9\" data-vc-accordion data-vc-container=\".vc_tta-container\"><span class=\"vc_tta-title-text\">Rebuilding What the Computer Can\u2019t See Anymore<\/span><i class=\"vc_tta-controls-icon vc_tta-controls-icon-chevron\"><\/i><\/a><\/h4><\/div><div class=\"vc_tta-panel-body\"><div class=\"vc_row wpb_row vc_inner vc_row-fluid wpex-relative no-bottom-margins\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n\t<div style=\"color:#6f737e;font-size:18px;\" class=\"wpb_text_column has-custom-color wpex-child-inherit-color wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<h5>Reconstructing File Systems and Partitions<\/h5>\n<p>Once a solid image or clone is in place, the work shifts from \u201ccan we read the media?\u201d to \u201ccan we make sense of it?\u201d Engineers use the raw layout in the image to rebuild the structures that the operating system normally relies on behind the scenes.<\/p>\n<p>With specialized tools, we rebuild partition tables, repair or reconstruct damaged file system structures, and locate lost directories and file records that the device no longer shows. Instead of relying on a standard mount, they work directly with low-level structures\u2014patterns, signatures, and remaining metadata\u2014to reconstruct how volumes and folders were arranged, enabling files to be accessed and recovered in an organized way.<\/p>\n<h5>Handling Complex Storage Layouts (e.g., RAID, Multi-Disk)<\/h5>\n<p>On multi-drive systems such as many RAID arrays and some NAS devices, there\u2019s an additional layer of work before file systems can be analyzed. Engineers may need to virtually reconstruct the RAID configuration to determine how the drives work together, in what order, and how data was striped or mirrored across them.<\/p>\n<p>Once the virtual layout behaves like a single volume again, engineers can examine partitions, file systems, and directories on the reconstructed virtual image as they would in any other case, then virtually rebuild the file system to extract the stored data.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><div class=\"vc_tta-panel\" id=\"1778863142853-29fab1c2-e7b7\" data-vc-content=\".vc_tta-panel-body\"><div class=\"vc_tta-panel-heading\"><h4 class=\"vc_tta-panel-title vc_tta-controls-icon-position-right\"><a href=\"#1778863142853-29fab1c2-e7b7\" data-vc-accordion data-vc-container=\".vc_tta-container\"><span class=\"vc_tta-title-text\">Validating and Extracting the Recovered Data<\/span><i class=\"vc_tta-controls-icon vc_tta-controls-icon-chevron\"><\/i><\/a><\/h4><\/div><div class=\"vc_tta-panel-body\"><div class=\"vc_row wpb_row vc_inner vc_row-fluid wpex-relative no-bottom-margins\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n\t<div style=\"color:#6f737e;font-size:18px;\" class=\"wpb_text_column has-custom-color wpex-child-inherit-color wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<h5>Checking File Integrity and Usability<\/h5>\n<p>Before results are returned, engineers look not only at how many files were copied, but also whether those files are usable. They spot-check representative samples of important data types\u2014documents, photos, videos, databases, virtual machines, and other critical files\u2014to confirm they open and behave as expected.<\/p>\n<p>Where appropriate, automated checks help flag obvious corruption or incomplete data, but human review remains an important part of quality control. No lab can guarantee that every file will be recoverable in every situation; the condition of the original media sets the limits. Our goal is to recover as much usable data as the device allows and organize it clearly, ideally in its original organization on the new destination, so it can be put back to work.<\/p>\n<h5>Copying Data to a New, Healthy Destination<\/h5>\n<p>Once the engineers have verified the files and they can be reliably accessed from the image or reconstructed volume, they extract the recovered data to a new medium\u2014typically an external drive or flash drive.<\/p>\n<p>The original damaged device, whether a hard drive, SSD, RAID member, or mobile device, is not considered safe for everyday use after a recovery. It is returned in its original unstable or partially damaged state. The new target device provides a clean hand-off for the recovered data, so you no longer have to rely on the damaged hardware.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><div class=\"vc_tta-panel\" id=\"1778863161700-efec703f-dea1\" data-vc-content=\".vc_tta-panel-body\"><div class=\"vc_tta-panel-heading\"><h4 class=\"vc_tta-panel-title vc_tta-controls-icon-position-right\"><a href=\"#1778863161700-efec703f-dea1\" data-vc-accordion data-vc-container=\".vc_tta-container\"><span class=\"vc_tta-title-text\">Secure Delivery and Post-Recovery Care<\/span><i class=\"vc_tta-controls-icon vc_tta-controls-icon-chevron\"><\/i><\/a><\/h4><\/div><div class=\"vc_tta-panel-body\"><div class=\"vc_row wpb_row vc_inner vc_row-fluid wpex-relative no-bottom-margins\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n\t<div style=\"color:#6f737e;font-size:18px;\" class=\"wpb_text_column has-custom-color wpex-child-inherit-color wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<h5>Encrypting and Shipping the Results<\/h5>\n<p>The final step is returning the data safely. Recovered data, along with the original device, is shipped back. For recoveries that contain sensitive data requiring encryption, the data will be returned encrypted.<\/p>\n<p>With the shipment, you\u2019ll receive clear instructions on how to restore the recovered data to a working device. We strongly recommend using the target as a secondary copy rather than your only working location.<\/p>\n<h5>Temporary Storage and Secure Deletion at the Lab<\/h5>\n<p>After the recovery process, a working copy of the data is stored in a tightly controlled, audited environment designed to protect sensitive information. Once the results have been returned to the owner and a minimum of a 14-day window has passed\u2014allowing time to verify the data and resolve any access issues\u2014the working copy is securely erased as part of standard security procedures.<\/p>\n<h5>Planning Your Future<\/h5>\n<p>After a successful recovery, many people use the experience as a turning point. Home users often strengthen their backup habits, and businesses may revisit internal policies around backup, retention, and testing for critical systems.<\/p>\n<p>For deeper guidance on building a long-term protection plan\u2014such as using multiple copies across different media and locations\u2014the\u00a0article that helps you protect data going forward.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><div class=\"vc_section vc_custom_1776432802256 wpex-vc-full-width-section wpex-vc-full-width-section--centered wpex-relative wpex-vc_section-has-fill wpex-vc-reset-negative-margin\"><div class=\"vc_row wpb_row vc_row-fluid wpex-relative\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\"><div class=\"vc_empty_space\"   style=\"height: 30px\"><span class=\"vc_empty_space_inner\"><\/span><\/div><style>.vcex-heading.vcex_6a0e9babc2bd1{color:#3e3d3e;font-size:45px;font-weight:400;}@media (max-width:1024px){.vcex-heading.vcex_6a0e9babc2bd1{font-size:30px;}}@media (max-width:959px){.vcex-heading.vcex_6a0e9babc2bd1{font-size:30px;}}@media (max-width:767px){.vcex-heading.vcex_6a0e9babc2bd1{font-size:30px;}}@media (max-width:479px){.vcex-heading.vcex_6a0e9babc2bd1{font-size:30px;}}<\/style><h2 class=\"vcex-heading vcex-heading-plain vcex-module wpex-heading wpex-text-2xl wpex-h2 wpex-text-left vcex_6a0e9babc2bd1\"><span class=\"vcex-heading-inner wpex-inline-block\"><strong><span style=\"color: #e31f26\">When Recovery Isn\u2019t Possible<\/span><\/strong> (And Why)<\/span><\/h2><div class=\"vc_empty_space\"   style=\"height: 20px\"><span class=\"vc_empty_space_inner\"><\/span><\/div><style>.vcex-heading.vcex_6a0e9babc33d5{color:#3e3d3e;font-size:30px;font-weight:400;}@media (max-width:1024px){.vcex-heading.vcex_6a0e9babc33d5{font-size:25px;}}@media (max-width:959px){.vcex-heading.vcex_6a0e9babc33d5{font-size:25px;}}@media (max-width:767px){.vcex-heading.vcex_6a0e9babc33d5{font-size:25px;}}@media (max-width:479px){.vcex-heading.vcex_6a0e9babc33d5{font-size:25px;}}<\/style><h3 class=\"vcex-heading vcex-heading-plain vcex-module wpex-heading wpex-text-2xl wpex-h3 wpex-text-left vcex_6a0e9babc33d5\"><span class=\"vcex-heading-inner wpex-inline-block\"><strong><span style=\"color: #e31f26\">Irreversible<\/span><\/strong> Situations<\/span><\/h3>\n\t<div style=\"color:#6f737e;font-size:18px;\" class=\"wpb_text_column has-custom-color wpex-child-inherit-color wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<p>Even with professional tools, some situations are beyond recovery.

In some cases, encryption without valid credentials creates a hard limit: if the keys or access methods are gone and no other route exists, the data may remain locked.<\/p>\n<p>These scenarios are the exception, not the rule.

Repeated DIY or repair attempts\u2014letting a clicking drive keep spinning, swapping parts without proper controls, running software on a failing SSD, or rebuilding a damaged RAID by trial and error\u2014can destroy remaining readable areas and overwrite fragments that might otherwise have been recoverable.<\/p>\n<p>These efforts can also complicate diagnosis by masking the original failure and adding new problems on top of it. By the time DriveSavers engineers see the device, they may need to untangle both the initial damage and the side effects of earlier attempts, which can make a successful recovery more difficult.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><\/div><div class=\"vc_section vc_custom_1775593082422 wpex-vc-full-width-section wpex-vc-full-width-section--centered wpex-relative wpex-vc_section-has-fill wpex-vc-reset-negative-margin\"><div class=\"vc_row wpb_row vc_row-fluid wpex-relative\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\"><style>.vcex-heading.vcex_6a0e9babc50eb{color:#3e3d3e;font-size:45px;font-weight:400;}@media (max-width:1024px){.vcex-heading.vcex_6a0e9babc50eb{font-size:30px;}}@media (max-width:959px){.vcex-heading.vcex_6a0e9babc50eb{font-size:30px;}}@media (max-width:767px){.vcex-heading.vcex_6a0e9babc50eb{font-size:30px;}}@media (max-width:479px){.vcex-heading.vcex_6a0e9babc50eb{font-size:30px;}}<\/style><h2 class=\"vcex-heading vcex-heading-plain vcex-module wpex-heading wpex-text-2xl wpex-h2 wpex-text-left vcex_6a0e9babc50eb\"><span class=\"vcex-heading-inner wpex-inline-block\"><strong><span style=\"color: #e31f26\">Next Steps<\/span><\/strong><\/span><\/h2>\n\t<div style=\"color:#6f737e;\" class=\"wpb_text_column has-custom-color wpex-child-inherit-color wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<p><span style=\"font-weight: 400;\">N\u00e5r din eksterne harddisk er krypteret, kan du begynde at gemme filer sikkert.
