CHAPTER 8 FILE RECOVERY: FINDING “LOST” IMAGES 107
Preventative Maintenance: Defragmenting Flash
Media
A defragmented hard disk drive can speed up disk writes and reads because files will
be stored contiguously (next to each other). As flash media increases in size, defrag-
mentation will become more of an issue. Currently, flash media is not large enough
to warrant defragmentation.
If you would like to experiment with defragging a large flash media device (any-
thing over 512MB), you will need a Windows PC. All flash media uses the FAT 16 or
FAT 32 filesystem, a byproduct of DOS and Windows. If you are a Mac user, bother a
friend with a PC and ask to defrag your camera’s flash media. The read and write
process on flash media is much slower than on a hard disk, so be prepared to wait
while this operation takes place.
The following steps are Windows-specific because only Windows is capable of defrag-
ging a flash media device (FAT 16 or FAT 32 filesystem). If you are a Mac user, use
the digital camera to reformat the flash drive, which will erase images and clean up
the flash drive in one operation. Follow these simple steps to defragment a flash
media card:
- Plug the flash media into your PC. You can do this using a flash media
reader that plugs into a USB port or FireWire port. - In Windows, double-click on My Computer.
- Find the flash media drive and right-click on it, then select Properties.
- When the Properties menu appears, click the Tools tab, then choose
Defragment Now. - When the Disk Defragmenter appears, click Analyze to determine whether
the disk needs to be defragmented. If a pop-up with the message “You do not
need to defragment this volume” appears, you can either close the applica-
tion or defragment anyway. - If you analyzed the media and still need to defragment, click Defragment.
Depending on the size of the media card, you should be finished in a minute
or two. - When the defragmentation finishes, you can view a report of the defragment
operation, or click Close and then choose File, Exit to exit the application. - Remove the flash media card from your PC. For Windows 2000 users, remem-
ber to detach it properly by clicking the Remove Hardware icon in the system
tray in the lower-right corner of the Start bar (next to the clock).
