Use a real logical block size instead of assuming 512 bytes when the backing device reports different geometry. Enable the crc feature when GPT CRC validation is required.

The returned start and size values are expressed in logical blocks. To open a filesystem safely, convert them with checked arithmetic and create a bounded partition view. See Open FAT inside a partition.
