File_ListPartitions()

File_ListPartitions(), Byte
Return value
— number of partitions found (primary + logical, up to 8)
Returns the number of partitions in SD card
Scans the MBR for FAT16/32 partitions (up to 4 primary slots), and if one of those primary slots is an Extended Partition container, also
walks its chain of logical drives (EBRs) - capped at 8 total partitions (primary + logical combined).
If sector 0 is itself a boot sector (no partition table), that counts as a single partition.
Requires the card to already be initialized (a prior File_Init() call).
