We got a Lexar Professional 800x in for data recovery. The Professional series are all based on Silicon Motion CF controllers with Intel/Micron NAND flash memory. Depending on the generation Lexar has implemented some interesting modifications, for example, doubling the…
We had the pleasure of recovering a monolithic FAR8GBHSTT24ADAK 8GB flash drive. It uses a hacked Alcor Micro AU6989 controller with a software bad columns implementation and 8GB Toshiba NAND flash memory chip. This monolithic chip has two data buses but…
If a flash drive isn't seen when plugged into a computer is can be for a variety of reasons. In this case the drive was dead, we took the NAND chip out of circuit and the controller booted into manufacturing…
Samsung came out with one of the first generations of Read Retry chips a few years back. Models: K9BCG08U1M, K9BCG08U1A, K9CDG08U5A, K9ABG08U0A based off the same die w/ an ID of ec d7 98 ca (0xecd798ca). Read Retry is a…
We received a flash drive without a case. It's a Silicon Motion SM3251Q BA 2GB flash drive w/ Toshiba NAND memory. When inserted into a computer it shows a phantom (grayed out) drive letter. This is the controllers safe mode.…
We were able to solve the pinout for the FAB8GBHSTS3SI2B & FAB16GHSTS3SI4B monolithic series of flash drives usually found in PNY and HP branded flash drives. It uses a Silicon Motion Controller and Samsung NAND memory. If you need your…
One of our customers sent us a flash drive that had been worked on by someone else. The first thing we noticed was that one of the pins on the NAND chip was missing. Luckily we're able to repair this…
We're now able to recover data from PNY High Performance SDHC Class 10 SD Cards. They use 2Y-nm (eg: 20-24nm) NAND Flash chips which required us to construct a special 1.8v/3.3 voltage leveling adapter and implement manual reference voltage adjusting…
