[HH] Different Mfg SD Cards will not format to same size

[Mark Komarinski]

Regular hard drives have the same problems which makes it fun when you try to use different vendors for a RAID array (as in, don’t, and be sure to get the exact same model for replacement drive)

Can you try to resize the FAT32 partition down a touch so it’s maybe 3.5GB?  Just be sure to keep the original image :)
