Over the years, fake flash memory products have caused numerous headaches. From USB drive or memory card errors, to corrupt data and eventual data loss, fake flash memory's global economic impact is something to take seriously. As any flash product can be faked or manufactured using low quality, failure-prone memory, it is necessary for consumers to prevent becoming a victim of lost data from the get go. The moment a consumer uses a flash memory product for the first time, they should be very clear of the flash's overall health and reliability. A simple yet very efficient way of analyzing a flash memory's health that industry insiders and consumers alike can use is the H2TestW burn in testing program. The H2 program was written by a German programmer for c't Magazin, is quite small in size, does not need to be installed, and includes English language support.
What H2 effectively does is "burn in" data to the flash memory. Once H2 is open and the proper drive has been selected, the program automatically detects the Operating System recognized storage capacity of the flash. If it has been set at a fake capacity, this fake capacity is what H2 recognizes. Say for example a low quality flash product of 2GB, or a 512MB product that has been set at a fake capacity of 2GB, in both cases, H2 detects the storage capacity of 2GB. Afterwards when H2 has started, it will successfully burn in 2GB worth of its own generated data into the flash. The next step is the crucial one, which is data verification. The data that is now stored, is then verified by H2. In the case of the low quality flash used, the H2 program will recognize the many bad sectors of the memory as the data will have errors when being verified. In the case that the memory has been set at a fake capacity, as soon as the data for the actual real capacity has been verified, any data H2 is trying to verify afterwards will end in error. For example, after 512MB worth of data has been verified, the data from 512MB to 2GB will all produce errors. In both cases, the H2 window interface will turn pink and display "The media is likely defective". If H2 says the media is likely defective, then basically there is no point in using an unreliable form of storage that will eventually lead to data loss.
For more info on the wonderful H2 burn in testing program, do an online search for "H2TestW" and read the countless praises for this secret weapon against the fake flash memory industry.
