Exactly. I had this problem with an external FAT32 formatted 160 GB USB
harddisk connected to a Siemens Gigaset M740AV video disc recorder
(embedded linux).

Though, you can tune this a bit by specifying the cluster size which by
default is 32 sectors (16 kB). Cranking this up to e.g. 128 sectors (64
kB) per cluster will reduce the FAT correspondingly by a factor of 4.
Thus the FAT of a 160 GB partition would have about 10 MB size as
opposed to 40 MB which indeed can generate problems on memory restricted
devices. The "-s" parameter of mkdosfs can be used for this.
