| Just format it with a proper tool?
There is probably Spyware on it. ¯\_(ツ)_/¯
| Use the formatting tool on the SD association's website, take note of the stats it spits at you when its done
| fdisk /dev/sdX (the microSD device)
Delete all partitions. Then create a new one to occupy all the space. Set it to be partition type 'c'.
mkfs.vfat /dev/sdX1
| OP here. Thanks, I know how to "reclaim" the unallocated space. But I'm, more interested in finding out why there's unallocated space im the first place.
| destroy SD and try to avoid gov agencies for the next month
| Guessing: as they must format them in bulk, they probably don't care about doing it reliably, losing a few megs is nothing if the method they use for formatting is 3 seconds faster
| Can you tell whether the unallocated space was at the beginning (before FAT) or end (after FAT)? Sometimes people would leave off empty space for various reasons, some being performance, some being usability, and some being laziness.
(But since this is /u/, always assume the 4 MB is a partition for FBI to put their keylogger.)

It's at the beginning (before the FAT partition). How would this affect performance or usability?

| The microSD card I just bought has about 4MB of unallocated/unpartitioned space, the rest is FAT. Is that normal?
