SanDisk 1TB microSD card.

Flash memory isn’t as susceptible to physical damage as hard disk drives (HDDs). Even so, physical damage occurs — particularly for microSD, SD, and other media formats that are designed for portability. 

If you’ve accidentally bent an SD card, the bad news is that you don’t have many options. Bending a card will sever the connections between the components needed to read and write data. SD and microSD cards have small form factors, and those essential components are packed tightly together; when they’re broken, data recovery usually requires the removal of the chip that stores your data. 

The good news is that the actual storage chip is fairly resilient. Even if you’ve bent your SD card in half, there’s a good chance that the data is recoverable — but you’ll need assistance from a professional data recovery provider. SD card data recovery requires specialized equipment that you won’t find at your local computer repair shop.

What is “chip-off” data recovery for SD/microSD cards? 

Chip-off data recovery is a destructive process in which the memory chips are removed from a flash storage device. It’s only considered as an option when the device’s controller or microcontroller unit (MCU) is no longer operational. 

In some cases, bending an SD/microSD card will not necessitate chip-off data recovery. If the bend damages the card’s voltage regulator, card pinout, or other components, those components may be replaceable — and professional data recovery providers will usually prefer to start with those components, since chip-off data recovery is technically difficult.

Is there any way that I can recover my own data from a bent SD card? 

Probably not — if the device is not recognized by your computer, you don’t have many options. We do not recommend attempting to “bend the card back” into its original shape; this will almost certainly damage the card’s components, potentially including the storage chip. 

You can safely try to read the card with another SD/microSD adapter, or by using another computer. If multiple machines are unable to recognize the card, you must either replace the card or contact a professional data recovery provider.

Can I recover the data by opening my SD card? 

In rare cases, some cheap SD cards contain microSD cards connected to a controller. If that’s the case, you could remove the microSD card from the enclosure and use an appropriate adapter to read the data. 

But this isn’t true for all SD card models, and if your device does not contain a microSD card, you risk permanent damage to the storage chip by opening the card. We would only recommend opening your SD card if you absolutely do not need data recovery (in other words, only attempt this if you’re curious about your card’s construction).

Heat issues are often caused by the card reader, not by the card itself. SD card sockets may short; if this is the case, the only solution is to read the card in another device. We recommend paying extra for SD card readers from well-known manufacturers. While cheap USB card readers are available, they’re more susceptible to the shoddy engineering that allows for shorts.

SD and microSD cards may also overheat due to physical damage. If the card has a crack — even a hairline crack that’s barely visible — the damage needs to be treated in a professional data recovery lab. 

If your SD or microSD card has any signs of physical damage, do not attempt to read the card in another computer or with another card reader. This could cause permanent data loss.

Why does physical damage cause SD cards to overheat?

When an SD card is damaged, there’s a good chance that the contacts inside of the card are also damaged, or that they’re shorting. 

Generally, though, the chip that actually stores the data will remain intact — and the card may still be temporarily readable, though it may build up excess heat during the read process. 

The cost of professional data recovery will be much lower if you can provide the SD card to the engineers in this state. If the contacts “melt” to the point that they’re no longer reading the memory chip, the chip will need to be removed and read separately. This is an intensive process that requires specialized equipment, so it’s often fairly expensive.

Can a camera cause an SD card to overheat?

SanDisk 1TB microSD card, designed for professional applications.

Yes. Many professional cameras have modes that take a large number of pictures quickly. Generally, the camera will store this data in some onboard RAM before writing it to the SD card — but writing a large amount of data very quickly can certainly cause heat issues.

This is particularly the case if the SD card isn’t designed for professional use. The hardware (in this case, the camera) may force data transfer rates at higher speeds than the SD card’s rating. If the hardware fails to vent the excess heat, you’ll get damage to the card’s contacts.

Standard SD cards have an operating range of around -25C to 85 Celsius (-13 to 185 Fahrenheit). Quickly writing data could push the card above this limit, depending on the engineering of the camera.

High-endurance microSD and SD cards have a wider range of operating temperatures, and some have additional features that limit the potential for data loss (for example, water resistance).

The SD format encompasses a number of related technologies:

• SDHC
• microSD
• miniSD
• SDIO
• SDXC
• SDUC

All SD formats are non-volatile flash memory — and as such, SD cards are generally more resistant to physical damage than hard drives or other magnetic media. However, no data storage format is perfect.

Data loss for SD cards can present a variety of symptoms:

• Files appear corrupt or unreadable.
• Files or folders “disappear” from the file structure. 
• The computer doesn’t recognize the SD card when inserted.
• The computer recognizes the SD card, but reports an inaccurate capacity (for example, a 128GB SD card shows a size of about 30 megabytes). 

Generally, SD card recovery has an excellent prognosis. However, flash memory must be treated in an appropriately outfitted data recovery laboratory — in most circumstances, your local computer store will not have the tools to safely recover your files. 

Common Causes of SD Card Failure

Below, we’ll discuss common causes of SD card failure. To learn about Datarecovery.com’s SD recovery services, call 1-800-237-4200 or schedule a risk-free evaluation online.

1. Firmware Corruption 

From a hardware perspective, SD cards are simple devices: They contain a printed circuit board (PCB), memory chips, and a controller that allows the card to interface with a reader. 

If the firmware becomes corrupt, the SD card may be completely unreadable. More often, it will present an inaccurate capacity. Your computer may ask whether you want to format the card — don’t reformat the card (unless you don’t care about the data).

Reformatting the card may resolve firmware corruption temporarily. However, exercise caution when storing data on an SD card that has lost its formatting or shown other signs of firmware corruption; the device will almost certainly encounter the same issue again. 

2. Data Corruption

Flash media stores data with electricity. In another article, we explained the basics of flash storage, but here’s the short version: A series of transistors hold electric charges to represent your data. 

Over time, the transistors become less reliable, which can be exacerbated by user behavior: 

• If you use your SD card regularly, the repeated writing/erasing causes memory wear, which raises the chances of corruption.
• If you let your SD card sit in storage for an extended period of time, charge leakage may cause corruption.
• If you unplug your SD card from your machine without going through a “safe disconnect” process, corruption may occur.
• If you suddenly shutdown an application or your computer’s operating system while it writes to the SD card, corruption occurs.

Corrupt files may be unreadable, despite appearing to have an accurate size, format, and other details. Corrupted images may be partially viewable, but a portion of the image may show random visual artifacts. 

3. Virus or Malware Infection

Malware infection is rare for many SD formats. Usually, you’re using the SD card to store a specific type of data (such as images or videos), not for general data storage.

However, data is data, and malicious software doesn’t really discriminate. Malware may target any storage device attached to a computer or smartphone. 

To resolve the infection, data recovery engineers will need to identify the source of the malware or ransomware. Learn more about our ransomware recovery services.

4. Accidental Deletion

Because of the methods that flash devices use to store data, deleted files may be unrecoverable once the operation executes. If you accidentally delete files or format your memory card, we strongly recommend ejecting the SD card immediately. Learn why we do not recommend using data recovery software for addressing accidental file deletion

If the files are important, contact a professional data recovery provider as soon as possible. Datarecovery.com provides a no data, no charge guarantee, and all of our flash memory recovery services include risk-free price quotes.

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).

The post Why a Flash Card Reports an Incorrect Capacity appeared first on Datarecovery.com.

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.

The card — unlike many other microSD cards in its class — offers fast read speeds of up to 160MB per second and write speeds of up to 90MB per second, although exact speeds will vary depending on a host of factors. That’s nearly twice as fast as standard UHS-1 cards.

SanDisk offers a limited lifetime warranty in most countries and notes that their card is “temperature proof, water proof, shock proof, and x-ray proof.”

Currently, the card is available on SanDisk’s website for $449.99. Some third-party sites are selling it at slightly higher rates, and the large price tag will probably scare off average consumers; however, the card could be extremely useful for photographers and videographers, as microSDHC offers a number of advantages over hard drives and other traditional storage media. The fast read/write speeds are especially notable for professional applications.

With that said, we believe it’s important to point out that larger microSD cards are not inherently better at resisting data loss than smaller cards. In fact, as form factors shrink, issues like data corruption often become more of an issue.

We haven’t had a chance to test the terabyte version of this SanDisk microSD card in our laboratories, but we’re ordering one now, and we commend SanDisk for the achievement. As larger cards hit the market, solid-state memory becomes more affordable for the average computer user, and this is certainly an exciting landmark.

Still, if you’re planning on purchasing a SanDisk 1TB card (or any other large microSD device), keep these tips in mind:

• Always backup important files as soon as possible. Never trust any single device to store essential data. We recommend keeping at least one backup of vital data, especially pictures, videos, and other file types that can’t be easily recreated.

• Don’t subject microSD media to extreme temperatures. While SanDisk’s new “Extreme” line of microSD cards are said to be temperature resistant to some extent, extreme weather can damage any digital device. Don’t expose your expensive new card to the extremes. If the card gets too hot or cold, allow it to return to room temperature before attempting to access data.

• Check your backups before deleting important data. Because of the technologies used to store data on microSD media, deleted files are often gone forever (although a number of factors can affect this, including the software or hardware used to manage the media). Check your backups before taking any actions that could result in data loss.

And as we always note, if you lose data from a microSD card, don’t panic. Stop trying to access the device and contact a qualified data recovery company as soon as possible. Most lost data is recoverable, and our facilities are equipped with state-of-the-art technology that allows for the best possible chances of recovery in any scenario. To learn more, call us at 1-800-237-4200 and ask to speak with a microSD data recovery specialist.

CD-ROM – Like audio CDs, CD-ROMs come with data already encoded onto them. The data is permanent and can be read any number of times, but CD-ROMs cannot be modified. The CD-ROM drive’s nominal speed is the same as its transfer rate. Single-speed drives have a 150KBps transfer rate while the rate for 12X drives is 1.8 Mbps. It is expected in the future that manufacturers are likely to shift from CLV (constant linear velocity) to CAV (constant angular velocity). While CLV rotates at varying speeds, CAV moves the disk at one constant speed. While this may not sound like much of a change to most, the difference is that this method is easier on the spindle motor because it does not require the drive to change motor speed as often, resulting in an improvement in performance.

WORM – Stands for write-once, read-many. With a WORM disk drive, the disk can be read and reread but once it is recorded it cannot be changed. After that, the WORM disk behaves just like a CD-ROM. The WORM drive is a high-capacity storage device and is best for storing archives and other large amounts of unchanging information.

Erasable-Optical disks – can be erased and loaded with new data, just like magnetic disks. These are often referred to as EO (erasable optical) disks.

These technologies are not compatible with each other. Each requires a different type of disk and drive.

An optical disk drive reads and writes data onto the disk. The disk is read by means of laser, then a magnetic field in addition to the laser is employed to write data onto the optical disk. The disk is exposed to a magnet on the label side and to the laser on the other side. A laser is used for two primary reasons: to allow a tiny one-micron diameter spot to be heated by an optical lens and the laser has enough energy to instantaneously reach Curie temperature (Curie temperature is 300 degrees Celsius, the level at which the magnetic domain loses its characteristic as a magnet).

Construction of the optical disk – The optical disk is mostly made of polycarbonate. The poly-carbonate plate should always allow the laser beam to transmit completely through the disk without a problem. Resin is applied to the disk substrate to ensure that the disk is not harmed in any way during the process (including heat damage, damage by impact, etc.). On the poly-carbonate resin substrate are seven types of film. Reflective film improves the read process. Protective film protects recording film.

Both first and second dielectric film protect the magneto-optical film, which is used for recording. Protective film protects the polycarbonate surface, and polycarbonate resin is a transparent plate.
