HTC One detected as CD Drive
These Chinese originated ROMs have a Win installer in them, if you tap the CDRom icon on ur PC it will install a " partner" Win app on your PC.
Just ignore it! When you connect your Phone to PC under the ADB settings notification just tick connect as USB storage and the next time you reconnect ur phone ( depending on the ROM) it will appear as another 2 or 1 additional USB drive.
Mine is a home cooked Lenovo Vibe 2.0 ROM (S939) and Lenovo has in most of its ROM this Win app installers. But I don't use them because they are cumbersome Chinese chracters only app. I used MOBOROBO if you happen to transfer file a lot from external sdcard.
