If the tool opens in Chinese, look for a "Language" or "English" button to change the interface.
This error occurs when the tool sees the USB controller but cannot identify the specific NAND flash memory. In the "Flash Setting" tab, you can try to manually select a compatible flash type. For the FC1179, users have reported success using IDs like 89D3AC32C204 or 89D3AC32C600 when the auto-detect fails.
One prevalent issue is the "Please insert a disk into the USB drive" error. A USB drive may be recognized by the system and display a drive letter, but attempting to access it yields a prompt to insert a disk—even though the hardware is physically connected. This issue often arises after improper formatting or firmware corruption. The solution, as documented by multiple users, involves using the MpTools and selecting the "Finished Product Open Card" (成品开卡) option.
The drive repeatedly connects and disconnects from the operating system every few seconds. Step 1: Confirming You Have a Firstchip YC2019
If you have ever encountered a corrupted USB flash drive that suddenly turned "Read-Only," showed "No Media," or displayed the wrong capacity, you may have unknowingly crossed paths with a silicon controller. Behind the plastic casing of many budget-friendly and promotional USB drives sits a small chip responsible for managing data flow: the memory controller. Firstchip Yc2019
Windows fails to recognize the device entirely, reporting a descriptor request failure.
is a textbook example of ultra-budget silicon. It serves its purpose by making digital storage accessible at pennies on the dollar, but it sacrifices longevity, speed, and reliability to do so.
The most notorious issue associated with the FirstChip YC2019 is its prevalence in fraudulent USB drives. This issue has become so widespread that it has drawn attention from both tech enthusiasts and mainstream consumers. The problem stems from the controller's programmable nature, which allows manufacturers to modify its firmware to misreport storage capacity.
Yc2019 / FC1179 / FC1178 (Note: Yc2019 is frequently grouped under the FC1179 or FC1178 architecture families in diagnostic databases). If the tool opens in Chinese, look for
After the repair, use a tool like to test the true capacity of the drive.
In the realm of USB flash drives, there are a few key components that make them work. The two most critical are the , which stores your data, and the USB controller , the tiny chip that acts as the brain of the drive. For millions of affordable USB flash drives circulating the market, the brains behind the operation is often a product from a company known as FirstChip (一芯) .

Set this to Low-Level Format (Refresh ECC) if the drive has severe bad blocks. Choose High-Level Format if it was simply a minor partition or write-protect corruption.
Extract the downloaded ZIP archive of the Firstchip MPTool to your desktop. Open the folder and launch the main executable file (usually named FirstChip_MPTool.exe or iCreate.exe depending on the exact software variant package). Step 2: Insert the USB Drive
The FirstChip YC2019 (chipYC2019/FC1179) USB controller is a fascinating microcosm of the modern flash storage industry. It represents affordable, accessible technology that enables widespread data storage, yet its flexibility has been exploited for widespread fraud. For the average consumer, understanding this controller can mean the difference between losing irreplaceable photos and documents, and safely using a restored drive for its intended purpose.
: This is a powerful tool. Incorrect settings can permanently brick your drive. Only proceed if you have backed up any important data (as it will be erased).
