is a compact, capless USB drive designed for basic file transfers and storage.
Every USB device has a unique "fingerprint"—the Vendor ID and Product ID—that helps your computer instantly identify what's been plugged in.
Try a different USB port (preferably a USB 2.0 port directly on the motherboard, not a hub). Test the drive on a different computer.
: This specific hardware ID (VID 0781 PID 5567) is often associated with a "write protected" error on SanDisk community forums , which usually indicates the drive has entered a permanent read-only mode due to a hardware failure . sandisk pendrive problem on disk write is protected usb device id vid 0781 pid 5567
The Vendor ID 0x0781 is registered to , a major manufacturer of flash memory products, including USB flash drives, SD cards, and solid-state drives. SanDisk (now part of Western Digital) has used this VID for over two decades.

The one-piece design eliminates the risk of losing a cap.
This is the most common issue associated with this hardware ID. When a SanDisk NAND flash controller detects that a memory sector has structural damage or has exceeded its write-cycle endurance limit, it triggers an irreversible fail-safe mechanism. The device automatically locks itself into a permanent read-only state to safeguard existing files from corruption. sandisk pendrive problem on disk write is protected
