If you are reading this, you have likely found yourself in one of two situations: you have a "fake" flash drive reporting false capacity, or you have bricked a USB stick while trying to fix it.
If you have ever plugged in a USB flash drive only to see "0 bytes available," or if you’ve encountered a drive that shows up in Device Manager but refuses to format, you have likely stumbled into the frustrating world of controller firmware corruption. For drives powered by the FirstChip (also known as ChipsBank or iStorage) controller family—specifically the CBM2099, CBM2199, and the CHIPYC2019 series—the standard Windows formatting tools are useless.
: MpTools cannot identify the connected chipYC2019 or fails to lock the port to begin operations. Solutions :
: After running a scan, the resulting usable capacity is significantly lower than advertised. Solution : This often occurs because the initial "Clear + Factory" scan creates a very precise, safe map of only the most reliable sectors. If the NAND contains many weak blocks, the tool conservatively lowballs capacity. The solution is to adjust the "Scan Level" in the settings. A Standard Scan or High-Level Format might produce a larger but slightly less-tested capacity range. Experiment with different scan types, but prioritize data stability over raw size for critical use. firstchip chipyc2019 mptools portable
The chipYC2019 is a specific, widely recognized controller model from FirstChip. Users often encounter this name through diagnostic tools like ChipGenius. It is frequently associated with the FC1179 controller family.

The is an essential utility for anyone dealing with flash drive repairs. Whether you are exposing a fake capacity drive or recovering a stick that Windows refused to format, this tool gives you the granular control needed to get the job done. If you are reading this, you have likely
The drive shows up as .
: The tool will scan for bad blocks and rewrite the firmware. This can take anywhere from a few minutes to over an hour. Troubleshooting Common Errors "No Media" / 0 Bytes
It includes a bundled repository of binary firmware files matched to specific NAND configurations, allowing the controller chip to re-initialize communication with the flash memory. : MpTools cannot identify the connected chipYC2019 or
controller, you can use hardware identification tools like ChipGenius. Running this diagnostic will output your specific controller model (e.g., Controller Vendor: FirstChip , Controller Part-Number: chipYC2019 ) and your exact Flash ID code (e.g., SanDisk, Intel, or Hynix). This critical information is required when setting up the repair parameters in MpTools. What are FirstChip MpTools?
: If you only need to change device descriptors, create CD-ROM ISO partitions, or edit configurations without a time-consuming sector-by-sector format, use FirstChip APTools.
Download the free gold-standard utility H2testw via Heise. Run a complete write-and-verify test across the entire drive volume. If the application logs a clean report with zero write errors, your FirstChip drive is restored and fully safe for daily deployment.
Flash drives are composed of two critical parts: the NAND flash memory (where data is stored) and the hardware controller (the brain that governs data flow). is a highly prominent manufacturer of cost-effective USB 2.0 and USB 3.0 controllers frequently found in budget-friendly flash drives, promo giveaways, and generic e-commerce listings.
Before launching FirstChip tools, verify your flash drive actually contains a FirstChip controller. Download a hardware reporter like or Flash Drive Information Extractor . Plug in your USB and check the report. Look for FirstChip listed under the "Controller Vendor" line. If it matches parts like FC1178BC or FC1179 , you can safely use this software.
