the same problem! using time machine + time capsule with os 10.6.2. on wlan - works excellently! but when trying to make an extra backup to an external harddrive (fat32, used also with pc:s), the copying of the iPhoto Library is extremely slow, the size is 46Gb and the system estimates 20-40 hours. Could anybody tell what could be the problem? Is it the Library itself? or the file system fat32 on the harddrive??
