Data+ 64GB USB Stick Repair, with SMI3271AD Controller
I had a Data+ 32GB flash drive with SMI3271AD controller for repair, which did not run and obviously could not be formatted. In such a situation, I use different programs. From the easiest programs that do not do specialized work to the most advanced programs. You can download all these programs from this link.
I ran the ChipGenius program and it gave the following output:
Protocal Version: USB 2.00
Current Speed: High Speed
Max Current: 500mA
USB Device ID: VID = 090C PID = 1000

I was able to find the suitable recovery program for this flash by looking for the part number of this flash on Google and the usbdev.ru website. We have two sorts of programs for SMI controllers: SMI Tools and Dyna Mass Storage Production Tool, which Dyna program is for cheap and economical SMI chips. I’ve seen a lot of garbage and low-quality flash, but this is one of the worst.
I tried with Star_SM3271series_S1215, Star_SM3271series_R0727 and Star_SM3271series_R1019 version, but it worked only with R1019 version. But unfortunately the flash became 16 GB. This problem has already happened to others and it can be solved by changing the ECC. But again, none of them worked. To read more or what the problem was, read here, here and here, or if you know, write in the comments.
