Test Fix Fake Flash Drives: Fake Flash Drive FAQ
Test works with files on top of the filesystem of the drive,so it does not know where each file ends up on the drive.It depends on the filesystem where each test file is writtenand how it may be fragmented.This means that the reported offset in case of an error is a file offset,not a physical offset and it might be much smaller than the real capacityof a fake drive.So if you've formatted your drive using a common filesystem like ext or btrfs,you can almost be sure that the logical file offset is unrelatedto the physical offset. For a volume test, you should format the drivewith the exfat filesystem (alternative: fat32/vfat).Many complex filesystems do not allow the full capacity to be usedas metadata and fragmentation can reduce the available capacityonce files are written.For that reason, there is a buffer, which should be around 1 MB.Some filesystems such as FAT32 do not need that buffer (SAFETY_BUFFER = 0).Raw disk testSome fake flash drives are extremely slow due to their sizeand the fact that they are not USB 3.0 devices (even though somehave fake blue-painted USB2 connectors).A volume test on a huge fake drive could take days in some extreme cases.For these cases, there's the disk test.It works with the whole USB flash drive, so if it contains a partition,that partition must be unmounted. It's "destructive" meaning overwritesthe drive, wiping its partition(s). When done, you need to reformat the drive,see the format item under the advanced menu (Linux only).The disk test is much faster than the volume test.On a good day, you can run this test on a 1TB fake drive and be done in minuteswhereas the volume test would take hours or even days to finish.However, the disk test is still somewhat experimental.If you have a fake drive that's not properly detected, please open an issueor send an email to the author (see below).Other feedback is appreciated as well.BuildTo start using CapacityTester now, it's recommended touse the pre-built binary file available for download on the releases page.To build from source, use qmake && make (see notes).If you want to help translating thisFake Flash Test - Fake USB and SD Card Testing - WinUSB

14 August 2024 Senior Product ManagerSummaryThe article discusses the prevalence of counterfeit USB flash drives that falsely advertise large storage capacities at very low prices. These fake drives appear to have the advertised capacity when connected to a computer, but their actual usable storage is much smaller. The article aims to educate readers on how to detect these counterfeit drives, the risks associated with using them, and introduces tools like Validrive that can help verify the true storage capacity of flash drives. The market is flooded with counterfeit USB flash drives that claim to offer one or two terabytes of storage at unbelievably low prices. These drives deceive buyers by showing the claimed storage capacity when plugged into a computer, but in reality, they may only have a fraction of that capacity. This article will guide you on how to detect fake flash drives, explain the risks involved, and introduce tools like Validrive that can help you identify the real storage capacity of your flash drives. Understanding Fake Flash DrivesFake flash drives deceive buyers into thinking they are purchasing high-capacity USB storage devices. Often these drives claim to offer terabytes of storage for prices as low as $9.99, but their actual usable storage capacity is far less. They use technical manipulation to misrepresent their capabilities.Genuine high-capacity flash drives, such as 1TB or 2TB, generally cost over $80. Flash drives claiming to offer terabytes of storage for a fraction of the usual cost are likely fake or of very low quality. If a deal seems too good to be true, it probably is. Detecting Fake Flash Drives Physical Examination Inspect the physical features of the drive. Fake flash drives often use generic housings or are built to look similar to legitimate brands. Look for inconsistencies in labeling, build quality, and specifications. For example, a drive claiming to be USB 2.0 but advertising fast multi-terabyte storage is highly suspicious because USB 2.0 is limited to a maximum theoretical transfer speed of 480 Mbps, which is not suitable for handling large amounts of data efficiently. Suspicious Listings Listings for fake flash drives often contain poor grammar, vague descriptions, and exaggerated claims. Descriptions like “Large-Capacity Storage: USB Flash drive super space” and promises of “excellent water resistance, magnetic resistance, high-temperature resistance, and X-ray resistance” should raise red flags. Identifying Fake Flash Drives with software Use diagnostic tools to check the drive’s reported capacity against its actual storage. Tools like Validrive, CapacityTester, MyDiskTest and H2testw can help determine if the drive is an expansion disk. Using ValidriveValidrive is a tool created by Gibson Research that helps identify the real storage capacity of flash drives. It works by writing random data across the entire supposed storage of the drive and then reading it back. If the data matches, the storage is real; if not, it is fake. To use Validrive, you can test a flash drive without erasing it. The software restores any pre-existing data if it tests a region already containing data. However, it isFake USB Flash Drive Test
DriveSavers BlogHome » DriveSavers Blog » Identifying Fake Flash Drives: Data Recovery Challenges and Solutions May 22, 2024 DriveSavers Blog USB drives have become essential tools for data storage and transfer. However, the market is flooded with fake flash drives that often cause significant data loss. This blog post aims to help identify these fraudulent devices, understand their impact on data recovery, and ensure data integrity. What are Fake Flash Drives? Fake flash drives deceive buyers into thinking they are purchasing high-capacity USB storage devices. These drives often claim to offer terabytes of storage for prices as low as $9.99. However, their actual usable storage capacity is far less, and they use technical manipulation to misrepresent their capabilities. Unrealistic Storage Capacity and Low Price At this moment in time, genuine flash drives with large storage capacities, such as 1TB or 2TB, generally cost over $80. Flash drives claiming to offer terabytes of storage for a fraction of the usual cost are likely fake or very low quality.The cost of flash memory stays mostly consistent between reputable fabricators, and genuine high-capacity drives reflect this in their pricing. If a deal seems too good to be true, it probably is. Physical Examination Inspect the physical features of the drive. Fake flash drives often use generic housings, or are built to look similar to legitimate brands.Look for inconsistencies in labeling, build quality, and specifications. For example, a drive claiming to be USB 2.0 but advertising fast multi-terabyte storage is highly suspicious because USB 2.0 is limited to the maximum theoretical transfer speed to 480 Mbps. This speed is not well-suited for handling large amounts of data efficiently, which would be a typical use for multi-terabyte storage devices. Also, check for signs of tampering, such as missing or non-genuine parts, and compare the drive’s exterior materials and finish to known genuine models. Suspicious Listings Listings for fake flash drives often contain poor grammar, vague descriptions, and exaggerated claims.Descriptions like “Large-Capacity Storage: USB Flash drive super space” and promises of “excellent water resistance, magnetic resistance, high-temperature resistance, and X-ray resistance” should raise red flags. These listings might also boast features that sound too good to be true, such as being indestructible or having an unlimited warranty. Case Study: Analyzing a Fake Flash Drive DriveSavers has a designated department where we specialize in flash memory data recovery. Here is a detailed examination the team conducted of a fraudulent “2,000GB” flash drive and what we found: Listing Claims The drive was advertised as a 2,000GB USB flash drive with features such as “Plug and Work” and “excellent resistance to water, magnetic fields, high temperatures, and X-rays.” Such exaggerated claims are common in fake listings and are generally irrelevant to the technical functions of the storage device. Behavior Under Test After writing 58GB of data, the drive stopped storing new data correctly. Instead, new files were added to the File Allocation Table at the beginning of the drive but were not actually written in full to the storageh2testw Test Programi - (Fake MicroSD Card - Fake Flash Memory Test

For a volume test, you should format the drivewith the exfat filesystem (alternative: fat32/vfat).Many complex filesystems do not allow the full capacity to be usedas metadata and fragmentation can reduce the available capacityonce files are written.For that reason, there is a buffer, which should be around 1 MB.Some filesystems such as FAT32 do not need that buffer (SAFETY_BUFFER = 0).Raw disk testSome fake flash drives are extremely slow due to their sizeand the fact that they are not USB 3.0 devices (even though somehave fake blue-painted USB2 connectors).A volume test on a huge fake drive could take days in some extreme cases.For these cases, there's the disk test.It works with the whole USB flash drive, so if it contains a partition,that partition must be unmounted. It's "destructive" meaning overwritesthe drive, wiping its partition(s). When done, you need to reformat the drive,see the format item under the advanced menu (Linux only).The disk test is much faster than the volume test.On a good day, you can run this test on a 1TB fake drive and be done in minuteswhereas the volume test would take hours or even days to finish.However, the disk test is still somewhat experimental.If you have a fake drive that's not properly detected, please open an issueor send an email to the author (see below).Other feedback is appreciated as well.BuildTo start using CapacityTester now, it's recommended touse the pre-built binary file available for download on the releases page.To build from source, use qmake && make (see notes).If you want to help translating this
2025-04-1114 August 2024 Senior Product ManagerSummaryThe article discusses the prevalence of counterfeit USB flash drives that falsely advertise large storage capacities at very low prices. These fake drives appear to have the advertised capacity when connected to a computer, but their actual usable storage is much smaller. The article aims to educate readers on how to detect these counterfeit drives, the risks associated with using them, and introduces tools like Validrive that can help verify the true storage capacity of flash drives. The market is flooded with counterfeit USB flash drives that claim to offer one or two terabytes of storage at unbelievably low prices. These drives deceive buyers by showing the claimed storage capacity when plugged into a computer, but in reality, they may only have a fraction of that capacity. This article will guide you on how to detect fake flash drives, explain the risks involved, and introduce tools like Validrive that can help you identify the real storage capacity of your flash drives. Understanding Fake Flash DrivesFake flash drives deceive buyers into thinking they are purchasing high-capacity USB storage devices. Often these drives claim to offer terabytes of storage for prices as low as $9.99, but their actual usable storage capacity is far less. They use technical manipulation to misrepresent their capabilities.Genuine high-capacity flash drives, such as 1TB or 2TB, generally cost over $80. Flash drives claiming to offer terabytes of storage for a fraction of the usual cost are likely fake or of very low quality. If a deal seems too good to be true, it probably is. Detecting Fake Flash Drives Physical Examination Inspect the physical features of the drive. Fake flash drives often use generic housings or are built to look similar to legitimate brands. Look for inconsistencies in labeling, build quality, and specifications. For example, a drive claiming to be USB 2.0 but advertising fast multi-terabyte storage is highly suspicious because USB 2.0 is limited to a maximum theoretical transfer speed of 480 Mbps, which is not suitable for handling large amounts of data efficiently. Suspicious Listings Listings for fake flash drives often contain poor grammar, vague descriptions, and exaggerated claims. Descriptions like “Large-Capacity Storage: USB Flash drive super space” and promises of “excellent water resistance, magnetic resistance, high-temperature resistance, and X-ray resistance” should raise red flags. Identifying Fake Flash Drives with software Use diagnostic tools to check the drive’s reported capacity against its actual storage. Tools like Validrive, CapacityTester, MyDiskTest and H2testw can help determine if the drive is an expansion disk. Using ValidriveValidrive is a tool created by Gibson Research that helps identify the real storage capacity of flash drives. It works by writing random data across the entire supposed storage of the drive and then reading it back. If the data matches, the storage is real; if not, it is fake. To use Validrive, you can test a flash drive without erasing it. The software restores any pre-existing data if it tests a region already containing data. However, it is
2025-04-15DriveSavers BlogHome » DriveSavers Blog » Identifying Fake Flash Drives: Data Recovery Challenges and Solutions May 22, 2024 DriveSavers Blog USB drives have become essential tools for data storage and transfer. However, the market is flooded with fake flash drives that often cause significant data loss. This blog post aims to help identify these fraudulent devices, understand their impact on data recovery, and ensure data integrity. What are Fake Flash Drives? Fake flash drives deceive buyers into thinking they are purchasing high-capacity USB storage devices. These drives often claim to offer terabytes of storage for prices as low as $9.99. However, their actual usable storage capacity is far less, and they use technical manipulation to misrepresent their capabilities. Unrealistic Storage Capacity and Low Price At this moment in time, genuine flash drives with large storage capacities, such as 1TB or 2TB, generally cost over $80. Flash drives claiming to offer terabytes of storage for a fraction of the usual cost are likely fake or very low quality.The cost of flash memory stays mostly consistent between reputable fabricators, and genuine high-capacity drives reflect this in their pricing. If a deal seems too good to be true, it probably is. Physical Examination Inspect the physical features of the drive. Fake flash drives often use generic housings, or are built to look similar to legitimate brands.Look for inconsistencies in labeling, build quality, and specifications. For example, a drive claiming to be USB 2.0 but advertising fast multi-terabyte storage is highly suspicious because USB 2.0 is limited to the maximum theoretical transfer speed to 480 Mbps. This speed is not well-suited for handling large amounts of data efficiently, which would be a typical use for multi-terabyte storage devices. Also, check for signs of tampering, such as missing or non-genuine parts, and compare the drive’s exterior materials and finish to known genuine models. Suspicious Listings Listings for fake flash drives often contain poor grammar, vague descriptions, and exaggerated claims.Descriptions like “Large-Capacity Storage: USB Flash drive super space” and promises of “excellent water resistance, magnetic resistance, high-temperature resistance, and X-ray resistance” should raise red flags. These listings might also boast features that sound too good to be true, such as being indestructible or having an unlimited warranty. Case Study: Analyzing a Fake Flash Drive DriveSavers has a designated department where we specialize in flash memory data recovery. Here is a detailed examination the team conducted of a fraudulent “2,000GB” flash drive and what we found: Listing Claims The drive was advertised as a 2,000GB USB flash drive with features such as “Plug and Work” and “excellent resistance to water, magnetic fields, high temperatures, and X-rays.” Such exaggerated claims are common in fake listings and are generally irrelevant to the technical functions of the storage device. Behavior Under Test After writing 58GB of data, the drive stopped storing new data correctly. Instead, new files were added to the File Allocation Table at the beginning of the drive but were not actually written in full to the storage
