What does Disk Manager show when the Blade is plugged in? And what does Device Manager show for Disk Drives and Portable Devices.
I don’t have a Blade but I do have a couple of Cruzers, and they have two drives built into them, one of which is a CD drive for U3 software. While U3 is gone I’m wondering if the Blade is keeping the 2 drive concept and using one for SanDisk software and one for user files. If your pc doesn’t have a drive letter available for both drives you could be looking at the wrong part of the Blade to format.
It’s a wild theory but so to is your situation. Let me know what you find.
