4gb microsd ..Battery consumption increase and slow transfer speed..

I noticed that when using my express with my Dane-Elec 4gb microsd (formatted to FAT (64 allocation size)) that battery life has been reduced. I figure its because of the refresh database each time the unit starts. Any thoughts on this? 

A major issue I have is that the transferring files to the 4gb microsd (while plugged into the express) is extremely slow. Around 1mb/sec. However when transferring in my laptops card reader, its around 4-5 mb/sec (class 4 card). The only issue with using the card reader and inserting back into the express is that the refresh database takes a very long time. About 25 min for 2.5 gb of music. If I transfer when the card is in the express, it will only take about 5 minutes to refresh but again the slow 1mb/sec transfer speed.  Anything I can do to improve the speed and not having a long refresh of database?

Anything over 2GB should be formatted as FAT32, not FAT.

I tried FAT32 and the express does not recognize the folders in it. Only works with FAT. Its there a particular allocation size of Fat32 that might work?

Fat 32 and 32kb allocation did not work with my sansa express. Would be interesting on what format everyone is using and transfer speeds with it.
