3. Better Error Handling: Instead of crashing on bad sectors, the new version skips them with clear warnings.

System Requirements

• Device not listed: ensure the drive is connected, try different USB ports, reinsert, or check Disk Management to confirm Windows sees the device.
• Permission errors: run the executable as administrator.
• Write fails or stalls: try a different USB cable/port, test the drive for hardware faults, or format the drive first.
• Image won’t boot: confirm the image type matches the target device’s boot expectations; some ISOs must be processed differently (e.g., hybrid ISO/USB or use Rufus/Etcher).
