: Sometimes used in "fake capacity" drives (e.g., a drive labeled 64GB that only has 8GB of actual space).
This specific combination of Vendor ID (VID) and Product ID (PID) is often seen on low-cost USB 2.0 or 3.0 flash drives. While sometimes branded as "VendorCo" or even appearing as counterfeit "Kingston" or "SanDisk" drives, the internal hardware is typically manufactured by . Key technical specifications often include: Controller: FirstChip FC1178BC or similar. Protocol: USB 2.0 or 3.0.
A frequent anomaly reported with this controller is that a drive advertised at 32GB or 64GB suddenly errors out after 2GB or 4GB of write activity, or truncates its own size during operation. This is usually indicative of a low-grade memory die or bad storage blocks. You can run the free industry-standard verification tool to check for true physical block limits.

Open (Right-click Start -> Disk Management).
Locate the disk list. If it appears as "No Media" with a blank bar, try changing the drive letter.
