The desired partitions should be established before formatting the drive(s). Using utilities like Partition Magic to alter partitions later does entail a little extra risk, and there can be problems if you use an older version which may not correctly handle things like larger drive sizes.
To convert to more than one partition, you would need to first shrink the existing partition to a smaller size, then create a new partition or partitions in the unallocated space that would become available.
Overall, since you reformatted the original partition anyway, a simpler way would be to go to Disk Management in Windows, delete the existing partition, create however many smaller partitions you wish and format them. If you want any of them to be FAT32 for legacy compatibility, Windows will not allow larger than 32GB size to be created.
If the diagnostic finds no fault with the drive, then the problem is probably just a glitch with the file system. Re-partitioning will most likely allow it to be formatted up correctly.
