![]() This can be useful for assessing the overall performance of the device. Read and Write Speed Tests: In addition to drive capacity testing, it can also provide information about the read and write speeds of the flash memory device.If the device is fake or if its actual capacity is smaller than claimed, the test will reveal this discrepancy. Detection of Fake Devices: H2testw is particularly effective at detecting fake flash drives that have been manipulated to report a larger capacity than they actually possess.It compares the read data to the original data to ensure that there are no errors or discrepancies. Data Verification: The tool performs a thorough data verification process after writing data to the device.This process helps determine if the device's claimed capacity matches its actual capacity. It writes a specific pattern of data to the device and then reads it back to verify the data integrity. Capacity Testing: H2testw is primarily used to test the actual capacity of flash memory devices.Here are 8 good reasons to use H2testw to check your USB flash drive. Note: To avoid the risk of losing important data, you should always copy your data elsewhere before performing a test. This portable utility supports both the English and Deutsch languages. To detect if a USB flash drive is failing or starting to wear out. Or for situations when the device has already seen a lot of use. ![]() This makes for a great tool to have on hand for testing if you think your flash drive might be counterfeit and reporting the wrong capacity. However, if the test finishes without errors, the pen drive is likely good. If the thumb drive has been programmed to display the incorrect size, or if it is damaged and no longer working properly, there will be data corruption. It works by filling the chosen target with test data and then reads this data back to verify it.
