I bought this 2GB mini sd card just before christmass for my PDA phone ppc-6700. the problem is any time the storage capacity on it reach the level of about 120MB it will hang and freeze my phone. i use software called SP tasck manager from binarys.com because i was not able to format it by using the windows xp on my laptop, but still the same thing. keep in mind that when i go to storage setting on my phone it will show me the right space left on it. Then i use it with the usb card reader on my laptop, format it FAT32 and loaded until it reach the same level and error from windows saying something like delay in wrinting... What can be done i can only used now as 100MB card not 2GB.
