Makes perfectly sense!
But I have to admit that I'm one of the few IT guys who almost never deal with Windows so others might need to jump in to correct me. If you aren't able to format the card in Windows (right click in Explorer or starting diskmgmt.msc from start menu --> "run"?) then this might be one of the few real use cases for 'SD Formatter' since this has an option "Format size adjustment" which has to be set to ON so that the card retains it's 'original' size (at least what the card's controller tells the OS). The card should then be exFAT formatted and can be checked directly using H2testw.
Please report back to let others know or to aid creating the Pine64' quickstart guide that should contain or link on stuff like this.
BTW: This whole 'card checking' thing could also be done later when running in Linux (but of course it's better to do it before directly after purchase of any SD/TF card).
The OS distro I contribute to -- Armbian, not available for Pine64 yet -- implements since a few weeks an 'armbianmonitor -c' mode that uses f3 to check the whole card when the SBC is already running. We do also a quick performance check since most if not all reports of 'Armbian being dog slow' are related to SD cards being way too slow regarding random I/O and +95% of all "Armbian doesn't boot or crashes continually" problems are related to either faulty SD cards or insufficient power supply.
