If you buy a USB flash drive at a certain treasure or a certain duo, and find that the USB flash drive with a large capacity, such as 128G, is damaged and cannot be opened after storing few things, you should use ChipGenius software to check whether the USB flash drive you bought is an expansion disk! Data is priceless. It's shameful to sell expansion disks! There are quite a few unscrupulous sellers who dare to expand their chips with less than 1G capacity to 16G, 32G, 64G, 128G or even 256G, 512G. Those friends who don't know how to do business and are greedy for bargains are the ones who dare to do business in one blow. When they meet such sellers, they directly complain and apply for a refund, which can generally be solved (successfully tried)! The seller does not agree to apply for waiter intervention on ChipGenius test evidence (not tried, if interested, try).
What if I have the misfortune to buy such an expansion disk? If you want to recover the damaged data, there is probably no way. Because a little bit of real storage capacity stores more than several times or even hundreds of times of data, it must be that the later writes erased and overwritten the previous writes, and there is almost no hope for recovery.
If you want to restore such a USB disk to its true capacity, first use ChipGenius to check the master control of the USB disk. Generally, many small fat USB disks use the core state master control. For example, the one I use is CBM2199S - [2018-12-01] (before mass production). After mass production, it displays CBM2099E, which may be related to settings.
If you test the master CBM2199S and try a lot of mass production tools but fail, congratulations. Read on and you will find a solution.
Simbond CBM2199S mass production tool UMPToolV7100 (UMPToolV7200
1. The tools used, APToolV7100_19-03 and UMPToolV7100_2019, can be found online.
2. Copy MPSetting.dll in the UMPToolV7100_2019 Dll directory to the APToolV7100_19-03 DLL directory
3. Change MPSetting.dll to APSetting.dll. Note that there is an identical dll under this folder (replace it).
4. Then click Set, you can see the mass production configuration information, and mass production is ready! (Click the setting and it will appear as shown in the figure below. That is, the UMPToolV7100 setting is placed in the APToolV7100 setting.)
5. I made a good package to share, remember to change the fixed capacity to 0 to restore it, I tried to expand the 512G of play settings and succeeded! Link: https://share.weiyun.com/V1GWPs3i Password: hy2guu
If it is successful, please leave a message and let me see how many people have bought the expansion disk!
