I kinda thought this also.
If this is the case then it means sandisk has changed something about there newer flash drives coming out of their factories nowadays.
Because I have always used these same computers with the "secure access vault".
Oh well I guess I can just use it as a regular flash drive until I learn to fix the problem or until I get a 64-bit laptop.
Is there any source that can confirm that sandisk has recently changed their "secure access vault" to 64-bit only?
