Formatting SD Card
New microSDHC memory cards come pre-formatted 
with a FAT32 file system which is optimized for good 
performance. The PDR relies on this performance and 
will never disturb the underlying low level formatting 
of the SD card. When the SMWB/SMDWB “formats” 
a card, it performs a function similar to the Windows 
“Quick Format” which deletes all files and prepares 
the card for recording. The card can be read by any 
standard computer but if any write, edit or deletions 
are made to the card by the computer, the card must 
be re-formatted with the SMWB/SMDWB to prepare it 
again for recording. The SMWB/SMDWB never low level 
formats a card and we strongly advise against doing so 
with the computer. 
To format the card with the SMWB/SMDWB, select 
Format Card in the menu and press MENU/SEL on the 
keypad.
NOTE: An error message will appear if samples 
are lost due to a poor performing “slow” card.
WARNING: Do not perform a low level format (com-
plete format) with a computer. Doing so may render 
the memory card unusable with the SMWB/SMDWB 
recorder.
With a windows based computer, be sure to check the 
quick format box before formatting the card.
With a Mac, choose MS-DOS (FAT).
