Canon BeBit (Japan) has just posted a set of warnings about the use of built-in Windows XP imaging features and potential problems associated with CF cards. The first part of the warning is about using XP's built-in image rotation feature, Canon note that doing so will destroy that all important EXIF information. The second part of the warning is about formatting CF cards, when formatting a drive under XP it sets the default filesystem to FAT32. Of course digital cameras only use and understand the FAT filesystem so you must remember to change the filesystem to 'FAT' before formatting you CF cards under Windows XP.
