Case study of SD FLASH DOCTOR:SM3210F-HY27UU08AG5A- 1-1
|
Basic info of the damaged USB Thumb Drive:
Controller : SM3210F
Flash chip model: HY27UU08AG5A
Chip count: 1
Channel count: 1
Now we will use our latest released flash data recovery doctor to recover the data in patient flash chip. The previous cases have elaborated how to remove flash chip from U disk as well as the way of adjusting flash chip to FLASH DOCTOR adaptor, therefore these steps will be skipped.
Step 1.Click the icon of FLASH DOCTOR application program twice to start FLASHEXP. EXE program, then click "import". As it is shown below:

Step 2.Sep up the location of project file from the pulldown list of "searching scope" in dialog box, and choose project file "project.ini" in the list box, then click "open"

Tips: current program file stores the program info in flash chip which has been accessed previously. If it the first time we access to the flash chip removed from certain patient flash storage device (or CF card/SD card/ memory stick), flash chip should be put on the exclusive FLASH DOCTOR adaptor, next start FlashEXP.exe program into a new window, first fill out the mode of patient U disk in "item info" column of item management, namely whether flash chip belongs to USB penddrive/CF card/SD card or memory stick. Then fill out the controller mode, commonly it will be marked on controller chip. Next, set the number of flash chip in patient device, our doctor support flash storage device with at most four chips. After set up these info, click "access to chip flash data recovery parameters automatically", info of memory chip will be obtained automatically, then click "save" to save the patient device info which has been set up and accessed to project. Ini.
Step 3.After importing info of program file, open "data mix" operating interface as the illustration shows, mix method can be done here. Its Operating order can be divided into following steps: analyzing chip order/setting unit structure, checking data in management module/setting management module structure and data mix method.

Tips: because flash chip adopts wear-leveling read-in management, the read-in data is stored at random. Moreover, we access to the data via the operating interface "access to storage chip", so the order of data in binary file FLASHCHIPx-x.bin produced by it is at random. And flash chips varies from different wear-leveling read-in, so when conducting data recovery, firstly management bytes info in flash chip should be restored via "data mix" interface, then rearranging these random data, so that corresponding data of files could be accessed.
Tips: now we can shift to "item management" interface, parameter info in flash chip has been accessed by program.
