KETRON USB & SD Card Reader Benutzerhandbuch Seite 16

B. FORMAT: Use this feature to
format your device (SD Card or
USB Stick).
NB:
KETRON USB & SD Card Reader doesn't require a safety procedure (as found on
computers) in order to disconnect external devices; therefore you can insert or
extract SD Cards or USB Sticks anytime so long as they are not being used (no file
is being played from them) nor any DISK function such as Copy, Move or such is not
being carried out. If you attempt to remove an external device which is currently
being used, this can result in damage to the files in the media being used.
