Not working on a 4Gb MS (not DUO one). I hace it, and the CLIEs are not able to read it. Any suggestions?

didn't work on a 4GB sandisk ultra II memory stick pro duo either. I went down to the local electronics store and had my stick formated in a psp. I turned aut the PSP didnt actually changed the filesystem so i ended up with a fat32 stick with some psp files on it. Maybe one have to format it to fat16 prior to formating in a psp. Formating it to FAT16 using XP without additional steps will not make the stick work in my TH55. (However it made the stick work in a P910i smartphone which also only supports FAT16, it failed formating there though)

Here is was I discovered in my various attempts on making it work using the memstick.ind and mstk_pro.ind files:
First thought was the file date and attributes have to be set correctly as this themes to be the only way as information could be coded into these files. No luck.
As the clie recognizes the stick without these files i don't think they are the key.

So i will try the psp approach further or formating on a sony vaio notebook...
