This option is for you to setup your z10 as a USB drive type device. The BB link wont recognize it to allow you to do backups. But works great as a drive on your computer. Then again you can access the Media card and device through explorer because it maps to your system as a drive in windows when Mass storage is off.

When Mass Storage is turned on, treats your Z10 as a hard drive. Can drag files with windows explorer. When mass storage is turned off, it will recognize your Z10 as a phone, but windows will also map to Virtual drives, one for the Device storage and one for the SD card storage. If you want to do a backup, then turn off Mass Storage on the phone, so that BB link can recognize your phone.
