Download FakeFlashTest v1.1.5
Download from the developer’s site (RMPrepUSB). The official file is a password-protected ZIP archive — see the file details below.
⚠️ Notice Regarding False Positive Antivirus Warnings
FakeFlashTest edits raw partition block architecture and changes volume sectors. Because it doesn’t utilize standard Windows software installer wrappers, security suites like Windows Defender or Avast might occasionally flag it as an unverified execution block. This is a false positive common with standalone hardware adjustment utilities. For proper testing deployment, make sure to execute as an Administrator.
Other download options
Unofficial mirror (Terabox): the same v1.1.5 package is also kept on a third-party mirror: Download from the unofficial Terabox mirror. The official source above (RMPrepUSB) is recommended, because only the developer’s copy can be checked against the hashes on this page.
Older build: an older v1.1.2 build is linked from the developer’s tutorial for drives under 2TB with 512e sectors (it may be slow on large drives): Download v1.1.2 from RMPrepUSB.
Caught a Fake Drive? Don’t Risk Your Precious Data Again
If FakeFlashTest flagged your storage device as fraudulent, discard it immediately. Counterfeit drives will systematically corrupt your memories and backups. We highly recommend replacing them with these verified, top-tier original alternatives.

How to Run FakeFlashTest in 3 Simple Steps
Since the tool is a completely portable 148KB executable, there is no tedious setup wizard. Follow these rules to diagnose your device safely.
Launch as Admin
Locate the downloaded FakeFlashTest_v1.1.5.exe in your local directory. Right-click the file icon and select “Run as Administrator” to grant low-level block write permissions.
Target Selection
Insert your suspected U-drive or MicroSD card reader. In the application’s top dropdown box menu, carefully select your target external drive letter. Double check to avoid internal disks.
Execute Quick Size
Click on the “Quick Size Test” button panel. A pop-up prompt will warn you about complete partition data erasure. Confirm the wipe statement and wait for your raw map log report. A small fake drive can show up within a few minutes — in the developer’s own example, a fake 16GB drive was diagnosed in 27 seconds — while large or slow drives can take much longer.
Verify Your Download
The developer states that the FakeFlashTest downloads do not contain viruses, and that you can upload the ZIP file to VirusTotal yourself to check it. We do not publish a scan score — instead, compare your file against the official hashes below, which is a direct check that your copy is the developer’s file.
Top 3 Alternative & Complementary Tools for Flash Auditing
If you require cross-platform support or need to investigate the specific controller hardware chip inside your drive, consider these industry-standard deployment alternatives.
🛠️ ChipGenius (Hardware Controller Investigator)
Windows CompanionWhile FakeFlashTest verifies the storage boundary, ChipGenius directly queries the database of the USB device controller chip (e.g., Alcor, Phison, SMI). It reads the raw VID/PID and NAND flash part numbers without inspecting sectors. It is the perfect complementary tool to identify the exact factory brand of a counterfeit drive.
Best used for: Identifying mass production controller models for drive flashing.🐧 F3 (Fight Flash Fraud – Open Source Powerhouse)
Linux / macOS NativeBecause FakeFlashTest is strictly compiled as a 148KB Win32 binary, Mac and Linux administrators are left out. F3 (Fight Flash Fraud) is an open-source command-line framework that compiles flawlessly on Darwin (macOS) terminal structures and Linux distributions. It performs exhaustive pseudo-random data fill verifications.
Best used for: Apple Mac computers, Raspberry Pi setups, and Linux servers.💾 MyDiskTest (Legacy Diagnostic Archive)
Legacy Windows OnlyMyDiskTest was historically one of the earliest blocks scanning interfaces deployed to pinpoint expansion drives. However, development permanently halted years ago, meaning it lacks proper multi-threading execution and fails on contemporary USB 3.2 Gen2 storage protocol stacks. It is only recommended for vintage diagnostic archiving.
Best used for: Old Windows XP/7 workstations checking legacy USB 2.0 thumb drives.Windows Compatibility & Execution Troubleshooting
Because FakeFlashTest bypassed heavy framework runtimes to remain a lightweight 148KB payload, review this technical deployment blueprint if it fails to execute on your environment.
| Windows OS Version | Compatibility Status | Required Prep Work |
|---|---|---|
| Windows 11 (23H2/24H2) | ✔️ Fully Supported | Requires explicit ‘Run as Administrator’ override context. |
| Windows 10 (64-bit / 32-bit) | ✔️ Fully Supported | Native execution. Ensure background file indexing is disabled. |
| Windows 7 / 8 / 8.1 | ✔️ Fully Supported | Requires functional USB 3.0 controller driver stack layers. |
| Windows PE (Preinstallation Environment) | 🔷 Premium Match | Ideal for deployment. The 148KB size loads purely into RAM caches. |
Q: The executable immediately closes or flashes a command box and disappears?
Fix: This occurs when a user executes the binary from an unextracted temp directory or an encrypted system root location. Move the FakeFlashTest_v1.1.5.exe directly onto your standard Windows Desktop or the root of your local C: partition, then try launching it again.
Q: My high-capacity external drive is plugged in, but the program selection menu is blank?
Fix: FakeFlashTest intentionally hides system storage partitions to protect you. If your external drive isn’t showing, it means it lacks a mounted volume layout. Open Windows Disk Management, check if the drive is listed as “Unallocated Space,” assign it a temporary drive letter (e.g., Drive G:), format it to exFAT, and relaunch FakeFlashTest.
Q: The test gets stuck or hangs at exactly 0% or a specific sector stream index?
Fix: This is a definitive physical hardware symptom. The program isn’t freezing; rather, the fake flash memory controller has crashed under heavy continuous write load, or the drive has disconnected itself internally due to overheating substandard components. Disconnect the drive, cool it down, plug it into a native USB 2.0 rear port, and test again.
