in my previous post the fat sizes were incorrct, it should be :
2GB FAT16 clustersize 32K : 2G / 32K * 2 = 128K
4GB FAT32 clustersize 4K : 4G / 4K * 4 = 4M
so the latter is 32 times as large as the first.

Subject: [bookport] beta. 4 GB CF FAT32 cluster size
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.
