  • Hello,
    I'm implementing USB mass storage device on LPC2148. My device is now detected but the properties show RAW data format and when i try to open or explore the drive i get error "Your device should be formatted" if i click on Yes it again gives error "The device cannot be formatted" . So i want to convert the data on my device to a format readable by Windows XP so which format i should use? From where to start? From where i can get code for it?
    are such codes available? How they can be implemented? I don't want to use SD card.
    Ya and which system would you suggest FAT or NTFS?
    Thank you.
