The good news is that dash cams aren’t magic boxes; they’re standard digital devices. They record video onto solid-state media — usually, internal memory or an SD card, though we’ve seen some units that can write to consumer-grade SSDs (solid-state drives). 

Flash media data recovery has well-established techniques, and in many cases, reputable data recovery providers can use those techniques to restore your video files from your damaged dashcam. Datarecovery.com even provides a no data, no charge guarantee: If a data recovery attempt isn’t successful, there’s no charge for the attempt. 

Now, the bad news: In some situations, dashcam data recovery is impossible. Below, we’ll discuss those scenarios. However, it’s important to note that every situation is different; even if you’ve lost data for one of the reasons outlined below, we encourage you to call 1-800-237-4200 to discuss your case with an expert.

If the flash device is physically damaged, data recovery may be possible depending on the extent of the damage.

If the solid-state storage is directly damaged, the footage is probably permanently lost — but this isn’t common. 

Flash memory uses electric circuits to store data. There’s also point-to-point signal traces that enable the storage device to communicate with computers (in this case, the computer in your dashcam). 

When a dashcam or its memory card sustains physical damage, it usually impacts those signal traces — not the semiconductor that stores your video files. Engineers may need to perform chip-off data recovery, which can be difficult and labor intensive — but if the data is important, it’s recoverable.

If files are deleted, data recovery depends on several factors.

The most important of those factors is the process used by the dashcam when the “delete” command is triggered. If the device deletes the video file’s entry in the directory table — or deletes the entire directory table — data should be recoverable.

However, for the best chances of data recovery, you must turn off the dashcam and keep it powered off. As the dashcam runs, it will overwrite data and render it permanently unrecoverable. This can happen quickly, especially if you’re storing data on a smaller memory card or if your video quality settings are high. 

In this scenario, we recommend working with a professional data recovery provider (and not just because we are a professional data recovery provider). The reason: In most cases, you only get one chance to recover your videos; a failed attempt could cause permanent data loss.

Reputable data recovery companies will create a clone of your storage media — either the dashcam’s internal storage, its memory card, or both — then restore the data from the clone. This prevents permanent data loss during the recovery attempt.

For a successful data recovery, keep your dashcam powered off

To recap:

• Don’t run the dashcam after you’ve noticed symptoms of data loss.
• Do not run data recovery software (and if you do so, make sure you research your options carefully). 
• Contact a professional data recovery provider that has extensive experience with solid-state storage. 
• Follow the provider’s shipping instructions (if shipping your device).

For years, “unsafely ejecting” a USB flash drive was a serious misstep — one that could lead to corruption and permanent data loss — but in 2024, it’s not as big of an issue. 

Here’s why: Operating systems have implemented protections to prevent computers from writing constantly to removable media. Since 2019, Microsoft Windows has included a “quick removal” feature, which disables cache disk write operations in order to make devices removable at any time. 

This sacrifices some speed, but given the high write speeds of modern media (up to 45 MBps via USB 3.0), it’s not a big loss — and since users are absolutely terrible at following instructions, Windows has established quick removal as the default device policy setting. 

So, what does “Safely Remove Hardware” do for a USB drive?

The “Safely Remove Hardware” option still exists, and if you’ve changed the policy settings of your computer, you may still need to use it when ejecting USB storage media. 

In simple terms, Safely Remove Hardware checks to make sure that all cache write operations have completed, then prevents the operating system from sending other write operations to the device. 

In even simpler terms, Safely Remove Hardware makes sure that the operating system is “done with the drive.” 

So, should I use “Safely Remove Hardware” or not? 

That depends on your operating system’s media removal policy. You can check this in Windows by following the instructions on Microsoft’s support page.

But if you haven’t changed any settings recently and you’re running a newer version of Windows, you can safely disconnect your USB flash drive as soon as the operating system has finished writing to it — no need to click the “Eject device” dialog. 

Of course, you can still eject your device if you want to be safe. That’s a good idea if you’ve installed any third-party software that manages your removable media. 

And whether or not you “safely remove” your flash drives, you should always remember that data is never safe when stored in a single location. Corruption and other issues can still occur, so follow the best practices of data backup.

If you’ve lost data from a USB drive, SD card, hard drive, or any other data storage device, we’re here to help. Datarecovery.com provides risk-free evaluations, and our no data, no charge guarantee ensures that you don’t pay for a failed data recovery attempt.

An internal view of a USB flash drive.

Chip-off data recovery (or chip-off forensics) refers to the process of removing the memory chips from a USB drive, smartphone, memory card, or another device that uses non-volatile flash memory. After removal, raw data can be extracted from the memory chips.

Because chip-off recovery is technically difficult and destructive, it’s a last-resort option intended for situations in which the device’s controller or microcontroller unit (MCU) is no longer operational. 

Data recovery technicians will usually attempt to repair damaged flash media components (for instance, the USB connector of a flash drive) or use software to restore the device to a temporary working condition. However, in some cases, chip-off data recovery is the only option. 

Common scenarios: 

• The device has sustained heavy impact damage.
• The device’s firmware is corrupt or unreadable.
• The device’s connector is broken or unusable (for USB drives). 
• The device has sustained damage from a fire or flood. 

Chip-off data recovery may not be an option if the device’s controller or MCU uses encryption. It’s also a highly specialized process: Technicians must have appropriate hardware tools to read the memory chips, and they must have an in-depth knowledge of data reconstruction techniques to restore the data to a usable state. 

If you’ve lost data from a memory card, USB drive, or smartphone, we’re here to help. Datarecovery.com provides risk-free evaluations for all flash media, and each of our laboratories are equipped to perform chip-off data recovery onsite. 

To learn more, submit a case online or call 1-800-237-4200 to speak with an expert. Below, we’ll explain the differences between chip-off data recovery and forensics, along with some tips for choosing a provider.

Chip-Off Forensics vs. Chip-Off Data Recovery

The terms chip-off forensics and chip-off data recovery are often used interchangeably. However, while computer forensics and data recovery are related fields, they have fundamentally difficult goals. 

For data recovery cases, the goal is to restore specific files to a usable state. If you’ve lost family photos on a USB drive, you’ll need professional data recovery services.

Forensic technicians look for evidence. In addition to specific files, they may look for records of when files were accessed, modified, or deleted. Additionally, forensics experts must maintain a chain of custody report to ensure that the evidence is usable in a court of law.

If you need computer forensic services, it’s important to find a provider that specializes in electronic discovery (or e-discovery). Tell the service provider upfront that you intend to use the results of the investigation as evidence; otherwise, they may not maintain an appropriate chain of custody.

Selecting a Chip-Off Data Recovery or Computer Forensics Provider

Chip-off data recovery is a highly specialized process, and because it requires the physical deconstruction of the flash memory device, any failed attempt will greatly reduce the chances of success in additional attempts.

In other words, you may only have one chance to recover data or find evidence. Some tips to keep in mind:

• Look for a service that can provide an upfront quote. 
• Because chip-off data recovery is a delicate and involved process, “attempt fees” are acceptable. However, ask about attempt fees upfront.
• Avoid data recovery companies that charge a flat rate for every type of device. Different memory cards, USB drives, and smartphones have extremely different architectures, so it makes little sense to offer a flat rate for every type of media. Read about the problems with flat-rate data recovery. 
• Look for a company with physical laboratories. Datarecovery.com operates full-service laboratories at each of our locations; we don’t operate mailing rooms that forward cases to a single laboratory. 
• Determine whether the laboratory is outfitted for chip-off data recovery. Ask about past cases and review the company’s testimonials.

The post What Is Chip-Off Data Recovery for Flash Media? appeared first on Datarecovery.com.

A SanDisk 1TB microSD card.

If your computer recognizes your flash card but presents an incorrect capacity, it’s probably due to firmware issues. 

Firmware is specialized software that provides basic instructions to your computer, enabling your machine to read the target device. 

If firmware becomes corrupt, or if it’s badly outdated, the computer cannot understand how to read your memory card — and the system can’t correctly identify the card’s capacity. 

While firmware issues are the most common cause of this symptom, other scenarios can create the same issue:

• Your memory card reader may be damaged, or may have a corrupt/outdated driver.
• Some memory card sellers intentionally change the card’s firmware to make it appear to have a much larger capacity. Read about a common flash drive scam.
• The card may be formatted in a filesystem that your operating system is unable to read. 

The quick solution is to update the firmware and reformat your memory card, but this permanently destroys all data on the device. If you need the files, contact a professional data recovery provider as soon as possible.

We do not recommend using flash recovery utilities on SD, microSD, CompactFlash, or other flash formats. Commercial data recovery software may contribute to file corruption and reduce the chances of a successful recovery.

Why causes flash card firmware corruption?

All data storage devices are susceptible to corruption, which simply refers to errors that occur during common operations (reading, writing, or processing the data). 

As the name implies, firmware is intended to be constant: Unless you’re actively updating your firmware, it isn’t supposed to change. For that reason firmware corruption is considerably less common than other types of data corruption.

However, firmware can still become corrupt for a number of reasons:

• You unplug your memory card while the computer is still reading/writing data. 
• Your computer shuts down unexpectedly. 
• Your memory card sustains electrical damage from a power surge.
• Your memory card sits in storage for an extended period of time. 
• Damage occurs due to a virus or other type of malicious software.

In most cases, firmware corruption occurs without any warning. Ideally, you’ll have a backup ready to go — but if you’re reading this article, there’s a good chance that’s not the case.

Can you recover data from a flash card with firmware damage?

Yes, but if a memory card reports an inaccurate capacity, it usually requires treatment in a professional data recovery laboratory. 

Engineers will likely utilize “chip-off” recovery techniques, which means that the memory chip is removed from the original device. This requires specialized hardware and software, but the chances of a successful recovery are fairly high. 

Some data recovery software vendors claim to be able to restore files from devices with firmware damage — but if the computer can’t read basic information from the memory card, neither can the software. If you absolutely need the data, we strongly recommend working with a professional data recovery provider. 

If you decide to format the card and lose your data, be aware that firmware problems can indicate that the card is approaching the end of its service life. Do not store important data on the reformatted memory card (or keep a backup in another location).

While most cases are recoverable, the resources required for successful USB drive repair can vary greatly depending on the extent of the damage. To determine whether your data can be restored, you’ll need a professional media evaluation. 

Get started by setting up a case online or read on to learn the basics of flash media recovery.

USB Drive Data Recovery: A Quick Overview

USB drives use a type of non-volatile storage technology called NAND flash memory. NAND uses electric circuits to store data; if those circuits are destroyed, the data is not recoverable. 

Fortunately, this is rare. USB drives consist of a NAND memory chip with point-to-point signal traces that allow the memory to “talk” with your computer via the USB port. 

When you physically break a USB drive, you’ll usually damage those data traces, but they may be repairable. By resoldering the circuit board, data recovery engineers can restore data access through the device’s standard interface.

Recovering Data from Severely Damaged USB Drives

In some cases, repairing the data traces isn’t practically possible. If the standard interface is too damaged, the engineer will need to remove the NAND chip(s), then connect it to an adapter. 

This isn’t as easy as it sounds: There are an enormous number of NAND chips on the market, and there’s no single adapter that matches the architecture for all of them. The recovered data must also be reconstructed into a logical sequence.

 So, what if the NAND chip itself is damaged? This is rare — most USB drives don’t break right at the NAND chip — but it’s not good news for data recovery efforts. 

The chip contains a small slice of semiconductor (a silicon wafer), which is extremely susceptible to physical damage. That’s one of the reasons that data recovery engineers work in certified clean rooms when treating NAND devices: Silicon is sensitive stuff. 

Even if a NAND chip is damaged, data recovery may be possible depending on:

• The type of NAND flash memory.
• The size and complexity of the files.
• The client’s budget.

In general, flash data recovery is quite affordable, but NAND damage can greatly increase the costs.

If you’ve read the headline of this article, you know the answer. However, we’ll make it as clear as possible: As of March 2022, most 2TB USB drives are scams. Currently, internet retailers are flooded with fake flash drives, and consumers need to take precautions when ordering storage media online.

Are 1TB and 2TB flash drives real?

Yes and no. While some reputable manufacturers offer USB flash drives with high capacities of 1TB or more, they’re not inexpensive. For example, Kingston’s DataTraveler Max 1TB drive costs about $180 (with free shipping). The 1TB SanDisk Ultra® Dual Drive Luxe USB Type-C Flash Drive is slightly less expensive at $114.

But neither manufacturer offers a 2TB USB flash drive for general audiences, and for good reason: High-capacity flash media is difficult to produce reliably, and most consumers don’t need to store a tremendous amount of data on a USB stick. External hard drives and solid-state drives are much better tools for transferring large amounts of data.

Over the past year, we’ve received dozens of “2TB” flash drives from consumers. In every instance, the devices fraudulently advertised their capacities.

What’s inside a 2TB USB flash drive?

With a quick search, we found 2TB flash drives listed for under $40 on Walmart, Amazon, Newegg, and eBay. To reiterate, reputable flash media manufacturers do not sell 1TB flash drives for less than $100.

We disassembled several of these storage devices (and we’re using the term “storage devices” liberally) in our laboratory. Here’s what we found.

Unsurprisingly, the drive was inexpensively made (and easy to disassemble). The NAND flash chip was generic and had no markings to indicate a capacity.

The drive’s controller is a Chipsbank CBM2199E AP35981. We believe that the “manufacturer” made modifications using widely available utilities to modify the perceived size of the flash media.

Of course, we wanted to know how the scam actually worked.

Hex editors are widely used in data recovery and computer forensics applications. When accessing the flash drive with WinHex, the total capacity seemed to exceed 1.9 terabytes. When we looked closely at the firmware, however, we found this device truly had only 32 gigabytes of storage space.

If you purchase a 2TB flash drive for $20-40, here’s what you can expect:

• Most devices include a small flash chip (from 8GB to 32GB) with minor modifications to a small amount of writable space located on the beginning of the drive.
• When accessing the drive, most operating systems will see a 2TB volume (or a 1TB volume, depending on the manufacturer’s claims). However, the actual capacity of the device is much smaller.
• If the user tries to write a larger file to the flash media, the drive will appear to function normally — but obviously, it cannot write to the sectors that don’t exist. Larger files will appear usable after the “transfer,” but when the drive is unplugged from the computer, the data will disappear.
• Because the drive is operating as intended, the user will not receive any error notifications when transferring files that exceed the drive’s actual capacity.
• Many brands offering 2TB flash drives offer some type of warranty. However, they don’t provide a warranty against data loss (and since the storage devices are functionally useless, getting a replacement drive won’t solve the consumer’s problem).

Avoid scams when buying USB flash drives

• Purchase storage media from reputable manufacturers. Look for companies that have an established history of technical achievements. Datarecovery.com does not recommend specific manufacturers, but with some quick research, you can easily determine whether a company is trustworthy.
• Don’t trust the user reviews. Scammers can manipulate ratings, even on trusted websites like Amazon and eBay. We found one “2TB” USB drive with 161 ratings. In many cases, the reviews reference a completely unrelated product.
• Never buy used data storage devices. Flash media has a limited lifespan, and used devices have fewer remaining read/write cycles. Read more about how flash media storage works.
• Avoid “too good to be true” deals. Cheap storage media is just that — cheap — and your data is valuable. While you might pay more for brand-name storage from a trusted retailer, you’ll pay less in the long run.

Finally, keep at least two backups of all important files. If a storage device fails, Datarecovery.com can help — but by developing a strong backup strategy, you can avoid a data loss disaster.
