file forward and backward navigation (keys # and *) has become very slow (more than ten seconds) on my BP with 4 GBytes CF, formatted on the BP which uses 4 KBytes cluster size. after reformatting with a cluster size of 32 KBytes, this problem disappeared. it should be noted that the fat size of a 4 GBytes FAT32 with 4 Kbytes clusters is 32 times larger than a 2 GBytes FAT16 with 32Kbytes clusters, 2 MBytes vs. 64 KBytes, which might result in performance loss on relative small computer systems as the BP is. i think that if one uses not a very large amount of very small files but only larger files, daisy and mp3, there is no need to use the small cluster size. BTW, I'm also testing a 8GB CF, and did not find problems until now, but my tests were not yet extensively. Chris S. -- No virus found in this outgoing message. Checked by AVG Free Edition.
