remove or recovery

Removable media is a form of computer storage that is designed to be inserted and removed from a system. Some forms of removable media, such as optical discs, require a reader to be installed in the computer, while others, such as USB flash drives, have all the hardware required to read them built into the device, so only need a driver to be installed in order to communicate with the device.Using removable media poses some risks, including data theft and the introduction of malware.Examples of media that require a reader include:

Optical discs (Blu-ray discs, DVDs, CDs)
Memory cards (CompactFlash card, Secure Digital card, Memory Stick)
Zip disks/other Floppy disks
