Windows limits FAT 32 partitions to 32GB so you will need either a mac or a third party format tool to format drives larger than 32GB as FAT32. SanDisk does not have a utility to do this. There is one I use called HP disk storage format tool. Google search for that and you should find a download link for it.
Hey Jeff, is there any way at all you can use NTFS? (or HFS+ if you have a Mac?) (Or perhaps the vendor of the equipment might know how to swing it?) It sounds like you went out of your way to get quality components, and you might not get your money’s worth with FAT32 given its history of poor reliability/consistency. I’ve had such bad experiences with data loss stemming from the FAT32 scheme that it has biased me here, but it would ■■■■ if you needed recorded data from the SSD only to find out the data cannot be retreived. :-/
