Werner Ruotsalainen at the PPC Magazine blog shares some good information on whether or not Pocket PC memory cards need to be defragmented, and how to do it.
Some tips:
* Yes, it's worth defragmenting them every 2-3 months, if there are frequent writes to the card.
* Never use a Pocket PC utility to do the defragmenting
* Do consider getting a card reader
If you have a card reader, the process is simple: Copy the files to your hard drive, reformat the card (E.g. "format i: /q /u"
but make sure you use the correct drive letter!), and then copy your files back to the card.
Card reader warning: If you have an old card reader (say more than 2yrs old), make sure you have the current firmware upgrade. Some of the older readers with out-of-date firmware can actually corrupt an SD card and render it completely unusable. I've had this happen, but fortunately I had a name brand card with a good warranty, and they were kind enough to provide me with a replacement. Unfortunately, the company that promised a firmware upgrade never got it to me and I finally gave up and threw it away after a number of months. Then they eventually did send me the firmware upgrade, but by then my old card reader was in the trash. Just as well because I wouldn't have trusted it anymore anyway.
