Enter your desired values for Vendor String ( TOSHIBA ) and Product String ( TransMemory ). You can also assign a random or static serial number string. Step 4: Execute the Mass Production Process
. It is widely deployed across standard USB 2.0 drives like the Kingston DataTraveler series and Toshiba TransMemory devices.
If you have a "dead" USB drive that is recognized by your computer but shows "No Media" or "Write Protected," you likely have a controller firmware issue. For drives using the Solid State Systems (3S) controller—specifically the TC58NC6623 (often rebranded by Toshiba) or the SSS6698-BA —there is a specialized solution known as an (Mass Production Tool). What is the TC58NC6623 / SSS6698-BA? tc58nc6623 sss6698-ba mptool
Insert your corrupted USB drive into the computer. Click the or Scan button inside the tool interface. The software will query the USB bus and assign your device to an open slot (e.g., "Port 1"). It should list the exact Flash ID string discovered during Phase 1. Step 3: Configure the Firmware Parameters
If the box turns yellow or blue, it recognizes the controller. Enter your desired values for Vendor String (
The is a highly specialized mass production software application used by hardware technicians to repair, reflash, and restore corrupted Toshiba TransMemory and generic USB 2.0 flash drives . When a flash drive experiences severe firmware corruption—frequently presenting itself as a "No Media" error, 0-byte capacity, or write-protection glitch—standard operating system formatting tools fail.
: The internal chip operates under dual designations. It is marked as Toshiba TC58NC6623 on the outer schematic but uses the Solid State Systems SSS6698-BA architecture internally. It is widely deployed across standard USB 2
If the drive is completely dead and undetected by Windows, you may need to open the casing and carefully short-circuit pins 29 and 30 (Data lines) of the NAND flash chip with a needle while plugging it in. This forces the controller into a generic bootloader mode, allowing the MPTool to detect it.
Reviving a corrupted, write-protected, or completely unreadable USB flash drive requires specialized mass production tools (MPTool). When a drive uses the controller—which is a rebranded Solid State System (3S) SSS6698-BA chip—standard Windows formatting utilities will fail. This guide provides the exact technical workflow to reflash this specific controller configuration. Hardware Identification
Because these tools are "Mass Production Tools," they can be technical. The following is a general guide to restoring a drive with this controller. 1. Download the Correct MPTool
often fail in these cases because the lock is at the hardware level.
