[Service Name] Removable Storage [Recommended Setting] Automatic/Disable* [Notes] 
Used for managing removable media. Disable this service if you do not have items like tape backup devices, etc. If your CD ROM/DVD Drive starts acting funny, place this service into Automatic. I also believe removable flash memory will need this service left on. It's your call.
